Bruh quit lying, I believe they call that the placebo effect 😂 btw that’s not how you spell octane 🤦‍♂️

That in my humble opinion was a very well done test, especially for not being in a controlled environment etc etc. And thank you for not throwing a whole lot of personal bias into the mix, that was refreshing as well. I for one would really like to see a test with the 5.7 between 87 octane, and the 93 octane. Overall gas mileage for a tank, and your tests from 40 to 80 and maybe a few more 0 to 60 and I would love to see the 40 to 80 in third gear, I think it would put the engine more in it's comfort zone, where it's designed to operate with a little performance. I mean let's face it Mopar turned a truck hemi into a really nice small block with a lot of horses for its size in 2011. Not to mention how much performance you can actually get out of one of these if you want. Anyway thank you, great video and now a subscriber.

Octane # is not about power or energy in fuel, its more about when it will detonate. Thats why engines with higher compression ratio need higher octane fuel. afair - alcohol based fuels have octane numbers more than 100, lol, but you will get worse mpg ( less energy per gallon, basically ) with it.

Octane is associated with power, when you consider that the ecu will pull timing (take power away) if it detects any knock. It's been noted before, and even insinuated by Chrysler/Dodge, that you will lose performance using 87 vs 89. Octane, in and of itself will not make power. But, when the ecm can add timing due to the higher octanes knock resistance, THAT will result in more power (however slight or significant that circumstantially may be)

Joe R power doesnt have everything to do with it. It is timing and compression. Hellcats are running 87 while the 6.4 is running 93. The 6.4 has a much higher compression because it is n/a. Now yes at one point the compression will be so high that you need an even higher octane. And power will follow but octane is not directly connected to power.

@andrewhigdon8346

Sak 20012019 but it is associated with horsepower. In fact horsepower is dependent on octane. On an older car without a knock sensor, higher octane will not give you more power right off the bat and with no other changes. But with modern spark control, higher octane will net you more power if the car was designed for it. So in essence, higher octave doesn’t give horsepower, it allows it.

Appreciate that experiment man. Getting one tommorow and this saved me from going to has up and run all the variables in my head. Appreciate you wasting money, time, and gas for other charger lovers!

I will just stick with 89 the recommended fuel. The 5.7 engine factory tuning does not have much flexibility for other grades of fuel. The knock sensors are heavily used running 87 when the engine is under load, with less power being the result, but most drivers will not notice that. For 93 octane with an aftermarket tune you can make more power, but with a factory tune the difference is not noticeable.

This has been a great video since I go back and forth between 89 and 93. Now the factory tune requires 89, so I'm sure they have some sort of rhyme /reason for that. Anyways - For what it's worth, it's a breath of fresh air to finally read comments without interjections from Internet trolls. That in itself was worth reading all the responses. Nice!

Love your vids man. You're very knowledgeable. Huge fan here!

I had a mazda before my challenger, noticed even though mazda claimed 87 was best that 89 gave me 10mpg better gas mileage, and that's not even a joke. It shocked even the mazda dealership. I tested the same thing in my v6 challenger, and get at least 5mpg better on 89 plus my engine sounds like its running smoother, i was getting a lot of what sounded like knocking on 87 like the owners manual said so again they should change it to ask for 89 due to just offering better gas mileage and a smoother running car. I would also like to add that in the future i do hope to add a RIPP Supercharger to my challenger before it gets too high in miles. Should make it a lot more fun to drive.

Hey! I really enjoy your videos and am considering getting an R/T myself real soon. I do think you should mention(in the description) what mods you have done to the vehicle though, because the mods could affect whether or not your motor will enjoy the higher octane.

It might not be good for racing, but it’s definitely good to clean your engine. High octane does clean your engine and that’s a fact. Higher octane has more detergents.

This is really no big question and did not require any test. I'm amazed how many people have watched and commented on this (I came actually to see your nice car!) You could google, but here is a simple explanation: The octane number has a totally different meaning than what you concluded as "generally higher quality" fuel. the higher octane is simply more resistant to pre-ignition so the engine can operate (be designed) with higher compression ratio. From thermodynamics basics, higher compression ratio increases the thermal efficiency of the engine, but practically you can not go very high in compression ratio, because the gasoline will pre-ignite. so, with using higher octance fuel, there is a little bit room to design the engines with higher compression ratio (As most modern engines are designed). So now with your experience with your eco-boost mustang and the apparent increase in the performance. I highly suspect this is the case: one source of pre-ignition is carbon deposits inside the cylinder. they heat up during the combustion (just like a charcoal) and keep the heat and at the following cycle during the compression cause the fuel mixture to pre-iginte and negatively affect the performance. (this carbon deposition is quite common in modern GDI engines like that of mustang), so basically when you put the higher octane fuel in your engine, you help the mixture not to pre-ignite by carbon depositions (remember? higher octane = more resistant to pre-ignition) and hence that negative effect on performance in eliminated. but basically you would get same improvement just with cleaning your engine from carbon deposits. So to conclude, theoretically higher octane never increases performance of your engine. if you experienced any increase, you just need to clean up your engine. P.S note: if you have even a bit of lower octane in your tank (lets say 87) and you add higher octane (93) the octane number of that tank will be the lower one (87), not the higher one or something between the two. so when going for higher octane try to consume all of your low octane (near empty tank) and go a few cycles of full tank-empty tank to wash out all the low octane.

Sorry but you're wrong. Mixing octanes does create a higher octane. Most gas stations use octane blending in their tanks. For instance, a gas station has 2 tanks, but 3 octanes they sell. That is because they have 87 octane and 93 octane. The high grade 93 and low grade 87 is blended to make the mid grade 89 or 91 octane. You were right about the other stuff though.

I am always amazed that people switch octane and expect better or worse results. what you have to do whenever you switch fuel is wait till your almost empty fuel up with the new fuel then take your battery cables off for 20 minutes to kill all power in your system once hooked back up your on board computer will re-set to the new fuel.

The shifting is definitely a lot smoother, try 93 you will see the difference on the pedal

Octane doesn't make you go faster. Octane, or AKI rating, is a measure of how much compression fuel can withstand before it combusts from pressure alone. Premature compression causes knock, which is extremely bad for engines. AKI = anti-knock index. The only power increase you'll see is if your car adjusts its compression & ignition in response to higher octane fuel. This would be a high-end, complex feature and gains would be minimal and perhaps even not measurable outside of a margin of error. It will also not increase fuel economy as higher octane does not increase the energy density of gasoline, so the same amount of high octane fuel is needed to produce the same energy as a lower octane fuel. The reason higher-performance vehicles require higher octane fuel is, typically, the engines are tuned for maximum power and run as high a compression ratio as deemed safe for components by the manufacturer. The fuel itself is actually the bottleneck here in most cases.

The higher the octane the slower the fuel burns. A slower burning fuel will push the piston farther down the cylinder making power over a longer duration of time. This is a must for combating spark knock or (pre ignition.) For testing a Stick shift would have been better, so you can lug the motor by having it in a higher gear (low RPM) and holding the motor wide open. This will produce the most spark knock and is much safer and faster way to test. If you can't make the motor produce spark knock moving to a higher octane is not needed and can produce less power.

Where I live the highest octane I’ve seen is 98

I have been using She'll 93 octane for over a year, it's advertised as a high detergent fuel, engine has gobs of power, 2009 challenger rt 5.7L.

Most newer cars with any amount of decent performance have the ability to ADVANCE TIMING what does this mean? The ECU will advance timing until it reaches the limit usually 93 octane on a stock tune... therefore the car will make maximum power that is can on that stock tune using 93 octane... if you ran 87 octane the ECU would have to pull timing thus resulting in a slower 0-60mph time , 1/4 mile time etc hope that helps... on fords twin turbo v6 motors they say that their torque/hp ratings are done with 93 octane.... using 87 octane is fine but the ECU will pull timing resulting in a slower acceleration best to use 93 if u care about max performance

Higher octane = less knock Knock = pulled timing Pulled timing = less power Altitude + map = preferred octane. After so much octane, you wont see a difference. That's why high altitude locations use lower octanes.

Regular there is 85 Octane.

If you have a custom tune, the octane does make a difference. On my 2004 Mustang GT, with 89 octane & tune, I produce 305 wheel horsepower. If I run the 93 octane & tune, I produce 315 wheel horsepower. So a tune can make all the difference

For me going to 91/93 made no difference on the seat dyno, what I liked was the fuel economy increase and how much smoother it ran. The plugs are cleaner and the MDS is much smoother.

You started out with 89 so the pcm has learned the fuel trims for that octane. When you put 93 in it, you won't see any performance difference unless you reset the pcm fuel trims. This will also reset the changes made to the base timing due to the 89 octane. Basically the test in the video was a show of his 89 octane tune learned in the pcm.

Unless it completed a drive cycle between the time he put 93 in the car and the test.

Probably been said a lot of times but I am not going to read all 223 comments. Octane does not give you more power, just higher octane on higher compression engines resists knock(pre detonation) more. Knock is the cylinder combusting slightly before the piston hits TDC (top dead center) and this is not optimal. Modern engines, with all their computer components can adjust for knock (by varying valve timing, etc), but only so much. Higher octane is the true fix. This is why muscle cars (high compression) use fuels like turbo blue with 110+ octane. They want their cylinders to BANG right when it is supposed to. So other than some slightly better gas mileage, you wouldn't notice much else. HP doesn't really increase. You may notice the engine running a little better, but it's not like adding an aftermarket bolt on that increases HP. Good video though. Very thorough.

I've always been big on using 93 Octane even though it hurts the pocket book, but watching this I will definitely look into 89 octane. Thanks, good job on getting those numbers!

Heh.. the comment aged horribly 😂

To any dodge charger owners..I have a 2012 rt... when I bought it guy was like regular is fine.. used reg, felt like it should be quicker but it was new to me so I didn't think anything of it.. then I read the manual after seeing this video and they recommend 91+ so I went to Chevron and shell and 76 did some testing.. 93 I feel makes it run too rich and fuel economy wasn't that great, so the happy medium after replacing all spark plugs and wires has been 91 Chevron! quick, and averaging 17 mpg!!! used to be in the low 13's with the same driving.. but after testing the high end gas stations my car likes Chevron 91... never put Arco or any low gas.

The higher octane is definitely a more completely burning cleaner fuel. Which is good for your valves, pistons and the environment .

I've seen many tests with different cars between different fuels and everything comes out the same. I was told the difference is, the higher the Octane, the less likely it is to burn outside of the tank, in case of a fire. But I have no idea.

You should try racing fuel. I put it in my head 2010 just to see what it would do, and only did it one time. The car definitely ran different with 100 octane fuel. Just suggestion on my part. Btw at $8.50 a gallon it should run better.

I personally don't get why you started in 4th gear, you aren't going to notice anything like that. You were better off letting the car stay in drive and auto select the gear it needed when you floored it. I've tried C12 in the tank and only noticed it was a bit more responsive and pulled a little harder but as for feeling a horsepower difference a dyno is the only way to see. Plus for the money, that's not even worth the test.

If he had pedal shifters I should see him starting in gear 3 n manually clicking up everytime he hit the rev limit

If you have a car with higher compression and you run a lower octane gas you either have to pull timing or you will have detonation and spark knock. By running a higher octane you can run more timing and therefore make more horsepower. This is why drag cars run race fuel or alcohol.

Brake boost??? you dont have a turbo to warrant brake boosting. Having 89 octane fuel in with your 93 will change the octane number FYI

That was a good video. The high octane rating used to be mandatory for a high compression engine to keep from detonating. It is no longer the case. The Ford 5.0 has an engine management system that is off the charts. It has an 11 to 1 compression ratio, but can still run on 87 octane. It does drop in HP, but the .60 cents a gallon you save is worth it.

Very clear presentation. The video and sound were very good. Keep up the good work. Your 40 - 80 test in a tall gear did not make any sense. Is that the way you normally drive? Your engine would take advantage of the 93 octane if you let it wind up in in the optimal power range. If you were afraid of damaging your vehicle with some full throttle, high rpm accelerations, sell that dodge and get a Ford Mustang like the one you referenced in the beginning of your video. That Mustang owner was not afraid to wind up his ecoboost a few times. Good luck and hope to see you again.

So. On a dyno, measuring max power, it’s legit 10hp difference between 87 and 89. The real difference comes into play on the highway, when your in eco. In 4cyl mode the computer advances timing, a lot. This why greater combustion is needed. Not for performance, but for economy. Now, if you get the vehicle tuned, 89 or 93 octane could greatly impact power. However, the factory ecm isn’t tuned for that

So I ran 93 in mine, got 25-26 mpg on the highway. 87 gave me about the same. 89, not even joking, I got about 29-30 mpg. Same route that I always take to Oklahoma. 89 just seems to give better performance/economy all around.

The difference between 87/93 is very minimal on a factory tune. The knock sensors are calibrated in such a way from OEM that it's almost not worth it:depending on the type of car, of course. I am on my 2nd Charger (1st was an 08 Daytona, 2nd is '13 Daytona) and I have run both. The 93 is necessary after a tune. Does it run just fine without a tune? Of course. But as the numbers show, not always worth that extra few bucks per fill. I have noticed a bigger difference on where I get my gas. If I am in a pinch and I go to a mom & pop corner store, my mileage suffers. If I run Shell, the car just seems to run a lot better. I know it does in my wife's EcoBoost Flex.

Thank you so much for this !!!! It was very helpful.

these cars will pull timing with the 87 but 89 vs 93 is less of an issue as long as you use good fuel. the computer is programmed to use 89 stock. I use 91(no 93 in CA/NV) more because I get my fuel at Costco, they don't have 89. but when I get gas on the road I get 89. my car has the stock tune still. programmers can give you a 93/91 tune that would make a bigger difference.

Realize that going from 87 to 91 or 93 is considered a modification. Whenever you modify the ecu(cars computer) will change it's parameters to keep driving normal. The actual horsepower comes from tunning the ecu to actually increase horsepower for the modification, in this case the 93 octane. There really is a difference in power for different octane. But you will only see or feel them with a tune. Same with exhaust, intakes, or anything.

The only real difference is what it's costing you to fill up.

it weird watching these videos when in finland i have never seen anything under 95... (if you dont count ethanol that is 85) generally there is only 2 options 95 or 98

Octane calculation is different in the US. Our 87 is like 95 (plus minus)

great video bro ! just what I was looking for, I use only 89 cause the 5.7 is not a high compression engine , 10.5:1 I think, but I was curious to see the difference between 89 and 93, thanks and keep it up man with the charger videos,, some good videos can be a camaro vs the charger or a 392 or a 5.0,

Me too, there seems to be a lot of these around everywhere

Test 1 was on a level stretch of road. Tests 2, 3 and 4 were on a downhill stretch. We are sure you know that!

How about the same test with a K&N Intake and performance computer tune, maybe even headers and then test the difference between 89 & 93 octane gas????

Basically use 89 for every day use and street use and 92-93+ for set racing

What the hell is wrong with his charger? My hemi don't accelerate that slow 😂

Good video and thanks for taking the time out to do this research without using a dyno....kudos...👍🏾

I feel like with in time after constant use of 93, you would get better gas mileage, better spark and a bit quicker, same as synthetic oil use, healthier for the car, longer lasting, overall better quality.

99% of these commenters don’t gave a car

I have a Honda Civic Ex it states 87 or higher in the car Manuel.. So I am stuck with 89. I don’t want to go higher. The reason is not to go faster it’s a 1.8 engine, it’s because I have always heard from mechanics and high octane users that it helps clean your fuel system when you use a higher octane. I love my car. Is a 2007 by the way.It works great. I wouldn’t change nothing. I have been driving it for one and a half year and have been using 89 ever since I bought it.

Your findings are hard to validate because there is so much more to how the engine will perform, with the outside temperatures and humidity being a big one. Seeings how the results were so close my take away is there is no difference.

Ive also been pumping 93 since I bought it in 2012. Idk if it helps or not, but I feel like it would make a big difference after 100k miles whether you've been filling up with discount gas or Shell V power, Ive been sticking with Shell btw

Chevron 94 😎

My Dodge p/u with 5.7 Hemi did not recommend 93 octane. Dodge designed the Hemi. Dodge built the Hemi. Dodge probably knows the most about their Hemi.

Well the lifters are known to seize and dodge knows this. Its been like this ever since theyve redone the 345 hemi on the chargers in 09 but theyve never done anything about it

(SUV) Chevy Trailblazer 2002 LTZ 4WD: When I go on road trips i use plus(89) when i do city i use premium(93) I notice no difference HWY with plus or premium i do notice it with regular burns faster has terrible smell from muffler. Believe it or not... 20" rims GoodYear Tires All Terrain, Airaid Air cool Filter, Throttle Body Spray cleaning and Marvel Mystery OIL Spiked My performance and gas mileage by... 35% So get to it.

Great video, great car! I have been driving around the 2015 charger v6 since last May and I absolutely love it. I can't wait until I graduate university and et the 2015 R/T. I have couple comments on the video regarding the testing, some stuff that you could have done in a better way. For instance when you filled it with 93, you filled it all the way to the max you mentioned, but you only put 16 gallons the first run. That could account for some extra weight. Second, I think it would be a better test if you were on a straight way rather going up or downhill. These are not major stuff, but these could make a small difference when testing! Overall great video, can't say I'm surprised with the results though! Keep em comin (Y)

+Wael Salem Both sets of test were done with full tanks of their appropriate gas. 89 octane filled up with 16.92 gallons while the 93 octane filled up with 16.67 gallons. The test locations aren't perfectly flat but I did 4 runs in the same spots for each fuel to keep it consistent. Thanks for the comment though and enjoy your charger!

Lower oct burns hotter. That's why you run race gas in a high compression engine. More oct allows advanced timing.

I use 91 octane in my 2007 Dodge charger RT, its tuned for 91..

I come to a different conclusion... the gas station sells the same gas from all Octane buttons! Scam alert. HeHe....

I started to use 93 octane without the ethanol or 100% fuel, and it has made a drastic difference in my 2015 Charger R/T.

How ?

I can't believe one tank last you one whole week!

hey man, really liked the review, seemed pretty well thought out. 2 things though....was your tire pressure in all tires the same on both days? idk if you know this or not but they say that a higher octane won't make a difference until you've put at least 3 or 4 tanks of it through your engine over time. thoughts/replies? thanks man!

It does not sound like your transmission is down shifting far enough going 40-80. Mine seems to shift down lower. My 5.7 only has the K&N cold air intake added.

A professor at a local college where i live told my friend there is no difference between 87 and 93...not sure if i believe him but he has taught that to all his students

This is great, thanks! I have the same vehicle, wondered the same thing. My car is in for a partial rebuild under warranty, all he said was something about the cam, I thought the cylinder head was being rebuilt, either way it started to misfire on the second cylinder and when they went in, it's an $1800 job but it is covered under the powertrain warranty. I never get gas from anywhere but Chevron, Costco or Tom Thumb, interestingly, I started having problems with my old Charger after I moved here and started using Tom Thumb gas. The Costco gas 87 is OK, but I wish they had 91, my car never runs that great after a Costco fill up. My sensitive flower of a Hemi is happiest with Shell, even 87. Oh, I'm in Dallas and I was told to fill up at the station near the Winstar casino in OK, everyone goes on empty so they can fill up there something about the gas not having additives. It's expensive but wow does my car love this gas! Great mileage, smooth as silk, lots of power. Weird, huh! Thoughts?

+Reason Very strange! I've never heard of a gas station providing better gas! I always thought they were all about the same since the industry is so highly regulated!

Dude your Murdered R/T looks pretty brilliant. What exhaust have you got?

I can't be bothered to check the comments to see if this has been said but.. 93 octane has a higher compression than 89, so if your engine has a lower compression, 93 will not burn properly. You'd get a dirty fuel burn and will lose power with 89 in the 5.7L.

hey bud, you should run a full tank of the 93 first then do the testing on the 2nd tank of 93. it takes a little bit for the computer to change all of the fuel trims that were stored from adaptive learning with the 87 or 89 you were previously running.

Just wish the Autostick in the 06-10 models worked the same as the paddle shifters.

Also, I would've emptied that first tank of 93, refilled, and used the second tank of 93 for testing. Dunno what kinds of funky results you might get with the mixed (even slightlly)

My 15 R/T has a mean 40 kick , I run mostly 93 , have seen the difference it makes at the track and on the street . Even higher will help too .. try sum octane boost ( a good kind ) ...

You have to give your car more of a chance to get used to the 93 to see better results. One tank of 93 after using 89 isnt gonna net any dramatic difference. Especially in a muscle car.

You should have tried shell v power nitro + is 93 and it there is difference between brands because of the quantity of detergent over the long run usage too. But really good video.

I hear running 93 octane in a 5.7 is bad for the engine if you don't have a tune

I use premium and I like to think it's healthier for that car rather than seeing a gain. I also realize this is an old vid, love the camaro btw

Not a fair test at all. You had 2.424 gallons of 89 when you went to get fuel. Thats 14.544 lbs. Then 19.1 gallons of 93 is 114.6 lbs. Every 100 lbs added or deducted is roughly 1/10 of a second in a 1/4 mile. You should have added about 3 gallons, drove it until the light came on, and then added enough 93 again to put it where the gas level was when you started testing. Anyway, your final octane with what 89 was left in it, was 92.492 octane. Formula is: (% x octane) + (% x octane) = final octane (0.127 x 89) + (0.873 x 93) = 92.492

I noticed a difference switching to ethanol free premium. But the price difference isn't worth it.

A lot of haters here in this comment section lol

As I'm sure it has been said in the comments somewhere, you are going to need a 93 octane tune to take advantage of the extra power that fuel would provide. If you had a 93 octane tune and did the same tests with a lower octane you would certainly see a power drop. If your car doesn't have an after market 93 octane tune and runs off of 87-89 octane you get the results that you came to during this test; although gas mileage may slightly increase. Good video by the way.

hahahahahaha check your eyebrows, you talk with them LOL
