Technically speaking an engine's compression ratio objectively determines the requirement for premium because its higher octane properties prevent detonation or "knocking" which can quickly damage an engine and higher compression engines therefore require premium. Any turbocharged engine should use at least mid grade although knock sensors can allow the use of regular by altering ignition timing this comes at a cost of power and mileage.

I use 98 octane which is twice as expensive as 95 octane and I can really notice a huge difference. The engine is not as noisy and the car accelerates much more aggressively and smoothly. Plus when i peek into the combustion chamber, the surfaces of the chamber is almost immaculate. If I ever notice a drop in acceleration, I clean the air filter and use the Abro fuel injector cleaner. It is cheaper than Chevron Techron and really does increase the performance. You can't convince me otherwise.

2016 Nissan Sentra here. Used regular gas from random gas stations for the first 2 years. For that last year and a half, I have been strictly using Costco Premium. Change from Regular gas from random gas stations to Regular from Costco increased my mpg by about 20%. When I went from Costco Regular to Costco Premium probably another 10% mpg plus my engine became much quieter and smoother including better acceleration. Moral of the story, there definitely is a difference between the quality of gasoline between different brands of gas stations, there is also a difference between regular and premium. I have even been asked if my car was a hybrid/electric due to how quietly it idles. PS: My UM recommends 87.

A lot of times vehicles are advertised as having a certain horsepower number when using regular, and a higher horsepower number when using premium. Did you test those vehicles to see if it is accurate? And does the cars computer take time to adjust to the different ratings. Did you give the computer enough time to adjust when doing your tests? I tried using regular in a vehicle that said premium was recommended(ND Miata), and it felt so incredibly sluggish that I immediately went back to premium.

Great info thx 4 sharing!

I am not sure what kind of cars Consumer reports really tested with Regular Gas vs Premium. Quite few cars take advantage of Premium (high Octane rating) in delivering more performance and delivering more mileage, esp cars with variable valve timing. If you read some of the Honda and Mazda statements, they do quote different Horse power ratings with Premium Gas. This is considerable amount of change. Several years ago I mistakenly filled my relatively new car with Premium and did not know I filled premium. I felt real gain in acceleration(also felt smoother) and surprisingly 10% plus gas mileage increase. I was not sure why. Next stop on return trip I filled at the same gas station usual regular grade. With in few minutes of driving I can see the difference how car is not accelerating as smooth as before, and saw decline in mileage also. Scratching my head, after going home while filing away my gas receipts, saw difference price per gallon, which turned out to be because of premium fill. But this alone did not convince me, because I know there is no difference in energy density of Regular vs Premium and car does not recommend or require premium. So after that I tested various combinations and found most of times the additional cost of Premium gas is covered by additional mileage I am getting. Did same test another car, which gained little in mileage or performance but not enough to cover the cost of difference. So moral of the story is, don't take Consumer reports as gospel and what they tell may/may not apply to your car or situation. Experiment your self, and know the difference and use your judgment. Initially I did not believe Premium would make any difference as there is no energy density difference, and unless the car is capable of leveraging additional compression ratio/knock resistance. A mistake gave me opportunity to explore and realize this.

I have proven it to myself over and over with the same drive. 89 extra K using premium. gas right now is 1.79 for regular (118.14$ to fill) that is 32 cents a k. Premium is 1.99 (131.34$ to fill) that is 28 cents a K. this is raw facts. cleaner and better all around. it is not wasted money... The gas company wants you to buy filler!!!!!!!!!!!!! its cheaper to make.

In Canada, consumer experts ran the same numbers and resulted in same result as you did. And they noted on the wording on the Gas cap as a simple guideline. However, my Audi A3 2.0T gas cap read Required. But when I pulled out my owners manual. It suggest to use 91 but you can use 87. The only issue with the lower octane is you may not be getting the optimal performance. So I just use 87 but if I’m going onto some spirited back roads driving, I could use 91.

If your car has a turbocharger, supercharger, or a naturally aspirated engine with a higher compression ratio, such as Mazda SKY-ACTIV engine, then you have to use premium gasoline, even if the manual says use regular.

What about the 3rd Gen Lexus RX 350? The 2010 & 2011 model years recommend Premium fuel, but the 2012 has the same engine, with no other changes noted, and they say Regular is okay? Is it actually okay to use Regular in the '10 & '11?

So that's why the clubs only have 2 grades, regular and premium. That's all stations need and I remember a 7-11 gas station in Texas had several grades to pick from like the pump thought it was a soda fountain.

Why am i watching this, I don’t even have a car

You are correct, the timing is constantly adjusting for Octane and several other factors, including air temperature and air pressure.

If you are going to put 87 octane in a engine that is designed to run on 91, the timing is ajusted immidiatly, because the computed will sence knock in the engine.

I appreciate this video, it keeps the consumer informed.

One thing you miss about mid-grade -- and where it does appear to be necessary -- is in the mountains. Typically, Regular gas in higher altitude areas is only 85 Octane . To get 87 Octane, you have to buy the mid-grade gas. It is "required," at least for some cars, by the manufacturer to run 87 Octane -- so these people should likely be buying mid-grade gas.

How to know if the gas stations are using the same gas for both butons regular and premium how do we know that?..that is why i preferred to Put regular gas so i dont feel i'm losing money.🤗 .

I've yet to see CR do a report to explain why some vehicles fairly represent their EPA rating while others are drastically lower.

What if u mix them

They should have done the mpg and acceleration test with turbocharged cars. Some new turbo cars you can use 87 octane. I like to see how it differs with a turbo.

What if you have a turbo and you need premium such as a 20 psi civic si have you ever driven it on 87? So sluggish.

Not that I need the info but no mention if your engine carbons up and you have to use premium fuel to keep it from knocking. That is one reason why mid-grade octane may be beneficial. My 2002 Silverado was built to run on regular but by the time I had 80,000 miles I had to use premium or else it knocked really bad, especially in the summer.

My 2021 civic says “87 and higher” notified premium makes my car respond a bit better than 87 octane but I honestly don’t see a mileage difference. Just the fact my car seems to respond a bit easier on premium opposed to 87.

My raptor requires at least mid grade fuel. I put in premium because I want it to make more power and run better. (Which it does seem to do). But I have no change in fuel economy between grades. I avg. 8-11 mpg lol. That race truck life is a hustle😆

I have a turbo so yeah use premium. But as long as you use factory recommended octane you'll be ok plus make sure its top tier on the y.

Measuring acceleration and gas mileage is all fine and dandy, but did you guys check for engine knocking or pinging? Car might drive fine but it may hurt the reliability if you use the wrong fuel.

If there is no benefit to using premium that can be found, is there any benefit/loss that CAN be demonstrated for those cars that DO require premium?

89 octane exists for older cars that start to knock on regular. Then you have an option to stop it knocking without going full premium.

Would be nice if you'd explain the proper reason some vehicles need higher octane!! It's not because of tuning that they need it it's heat caused by higher compression ratios and forced induction! That heat causes pre ignition when using 87 octane! So higher the octane the higher the temperature the fuel will ignite itself without a spark! Gas companies should not be allowed to call it premium because there's nothing premium about it!!

I use premium fuel because it makes my car run smoother due to cleaner combustion and because it’s a much cleaner fuel in general. And I do care weather I’ll have to clean my intake valves or not because of poor quality fuel usage. Is there a difference in fuel consumption? I think there is, yes. But I’ve had my car tuned to take advantage of it.

Acura is infamous for "requiring" premium fuel. I just use it because it says it's required. It doesn't say recommend for me. I hardly have any issues with my car. A lot of people debate this but I am not the type that wants to have my car misfiring or having engine problems later down the line.

My car is Toyota Prado V6 2015 in manual said for optimum engine performance run 95 Octane if not found you can use temporary Octane 91 but from my experience if I use 91 engine develop sometimes knocking specially in city driving but in highway no difference for that I use most of the time 95 Octane

Very poor explanation from a technical standpoint. The fact is - as the video correctly states - putting premium fuel in a car designed to run on regular is a complete waste of money. However, very few production cars today have engines that will not run safely on mid grade or regular fuel. The ECUs in cars today, along with knock sensors, can calculate the degree to which an engine is prone to pre-ignition or detonation and compensate instantly, minimizing the effects of lower octane fuel in a premium fuel-designed engine. The tests CR should have done would have been acceleration and fuel economy using regular fuel in cars with a premium fuel designated engine. In the long run, saving $200 per year by running regular in a premium fuel engine is a poor bargain, if doing so does actually put your entire engine at risk. How many years of $200 per year savings will it take to pay for a $15,000 engine rebuild? And, the remarks about mid grade are utterly specious. They smack of the "Big Oil" type conspiracy theories that CR loves to indulge in. That's not responsible journalism or objective science at all. It's editorializing. Mid grade fuel is exactly what it says it is. Mid octane. What's the problem?

Whe storing gas I use no alcohol fuel and ad the Stabil preservative to decent gas the alcohol puls water out of the atmosphere and the gas won't store as long.

Premium is 1.99 (131.34$ to fill) that is 28 cents a K. this is raw facts. cleaner and better all around. it is not wasted money... The gas company wants you to buy filler!!!!!!!!!!!!! its cheaper to make.

If your engine has 10:1 compression ratio, and a four barrel carb, chances are good you better use premium. My test is a 15% grade and moderate throttle. If I can barely hear the valves chatter it's just right.

gas is gas unless your car requires premium

Check the manual, If it says Use 87oct=use +87oct premium recommended=use +91oct Use premium only=use +91oct Engines aren't cheap so dont cheap out on your engine, give it the fuel it needs to run properly.

Look at your owner's manual. But you also need to see if your engine can even run on regular gasoline. My Outback 3.0R with a high compression 10.7 to 1 3.0L H6 says it can run on 87, but the performance felt sluggish and my 17-18 mpg average dropped to about 12. When I put 93 octane back in, the performance went back to normal and I went back up to my average mpg. The delta from premium gas to regular gas is only about 5-7 dollars a fillup (~10%) for me but the fuel economy delta is significantly larger. Some engines will retard timing so much, any savings on 87 could be potentially lost when your car gets atrocious fuel economy and real noticeable lost performance. Normal engines it is a waste to put in 93, and actually can be a net loss in fuel economy (additives make the fuel resist pre-detonation, reducing/eliminating knock). But if you have a performance car, a luxury car, or an engine with high compression, you NEED 91/93.

10 tanks means two or three months? Has weather changed? Did you span the blend change dates? Did you use the same station, and did they keep the same supplier and did the supplier pull from the same big storage tank. All these variables can make a 5-10% difference.

Calculate your cost per mile to determine whether you still save money despite 2mpg loss

So... I usually use regular, but only enough, my local family-run gas station has been out of stock for the past few weeks of regular and mid-grade fuel... So they discounted premium to the regular price! Their regular price is already 8c/gal less than every other big chain gas station in my area (including the gas station directly across the street from them...) So... After using the super discounted premium, my car has had some engine knocking (or the engine runs odd). I could switch back but it LITERALLY saves me MORE money at the moment to use premium... Help? Advice? Please and thank you.

My Dad bought Premium for his Ford Taurus. I told him that was only for the Taurus SHO, but he continued using premium. Some Dads don't listen.

my car develops less carbon exhaust on hi-test than 87 octane. my car is designed to run on 87 but has no must run instructions on octane. i use 93 octane in my walk behind mower and the rpms are more per tach i have on mower and i think it is because the mower is not building up carbon because when i use 87 octane in the mower, the rpms are lower (less power which is a pain in the early spring when the grass is thick and lower rpms clog the shoot). just my observation from real life.

93 is premium??? In my country it only have 95, 98 and V Power for shell petrol station.

Use something that just needs regular. You don't get that cash back and it's a non renewable resource. Plus, there are lots of cars and trucks these days out there that ride like luxury cars but just need 87 octane.

2:27 there are a couple cars that say to use 89 octane and that includes 2006 Dodge Charger RT.

Wow I didn't know that. Some places, like Costco for instance, don't even sell the mid grade 89 octane stuff.

Correct, I have a 2009 Chrysler 300 with the 3.5 engine and it recommends 89. I had been using 87 for years until I read my owners manual one day. When I started running 89 until the second gas tank I noticed my car had more horsepower but the MPG was still the same when I had used regular.

Why blur out the car's emblems???

Many modern computer-controlled turbocharged engines can take advantage of higher octane, up to a point. It depends upon the exact vehicle and engine, however. Most of them can run fine on lower octane gasoline, but may see a small performance boost with higher octane fuel. This is generally NOT true for naturally aspirated engines, however. My particular turbo'd 4-cylinder vehicle runs fine on 87 octane, but gets a small but noticeable performance and mileage increase with 89. Going to 91 seems to make no difference, and of course, costs more. Do your own research, read the forums where owners are discussing your make and model of vehicle, and of course, there is always dyno testing, if you really want to know the actual performance numbers.

I put 30% vegetable oil and 70% regular gasoline in my car so that the 30% can mix with the gas and bc its cheaper i save more money that way, works perfectly fine

Higher octane fuel burns slower and is designed for engines that have a longer stroke and need fuel to burn slower during the cycle. Short stroke engines need a lower octane fuel since it burns faster. Check your manual!

I mean the Ford f150 with either EcoBoost (2.7 or 3.5) recommends 87 octane, but both the fuel efficiency and power/torque are measured with premium and regular gets you a 15% loss for both roughly. Also mid grade fuel is like literally made for the hemi, as I dont know any other engine that uses it

If only Premium was actually 91 octane.. Check out gas trucks filling 'by mistake' the Premium station tanks with a little bit of Regular

You didn't mention if the premium gas is cleaner than regular gas more pure and doesn't leave residue in the engine.

Sure things CS. $400 a year v. Injectors, Cats, Turbo, PCV, Valves... I'm not a rich man but I know I can afford $400 per year over needing to really deal with a single one of those things for basically any vehicle. Quick math: 1 Tank = 400Mi = 18USG. 10 Tanks = 4kMi = 180USG. 100 Tanks = 1800USG = 40,000Mi. 3x18=54, 1 Tank = ~$54. 54x100=5400 ==> 100 Tanks at $3 gallon costs about $5400. That's 2 years worth of gas, as per NHTSA average. The labor to do one of those jobs is typically about a grand if you want it done right, and then you have parts and the risk that other things break while the repair is being made... plus in the inconvenience of it being in the shop. Sum all that up then figure out the easy easy way to avoid all that (mostly, Lord willing) is to use excellent fluids at the correct intervals and there's no way around concluding that some extra shekels towards excellent fuel/fluid is the way to go.

What I often find is missing In these videos is that in Canada at least, the 87 and 89 octane fuels contain ethanol whereas 91 does not. If all versions had ethanol then there would be no efficiency difference, but if comparing 87 with ethanol and 91 that does not have then there will be a difference in efficiency. I have tested this myself on numerous vehicles.

The US is different. Very few cities have non-ethanol gas at regular gas stations, regardless of premium or non. They are the same 10% mixture.

85 Octane is the low here in CO. :(

I think super is best for snow , & I still think old saying , ya get what you pay for . Try super one time you'll feel it boy wooo .

What they fail to tell you. Not all regular gasoline are the same , Top tier has more additives that reduces carbon build up! Some brand produce slightly higher combustion energy.

There's a reason they didn't mention that: BECAUSE IT'S NOT EVEN REMOTELY TRUE. All modern gasoline (regardless of brand/octane) is loaded with cleaning agents. The last time you heard someone had engine trouble because their gasoline didn't have enough additives? Never.

Thomas Ferrugia - I generally use top tier (Shell, Mobil, BP, Exxon, etc) because their detergent additives are supposedly a lot better than the minimal federal standards. But I do agree that it’s overstated. All gasoline in your area comes from the same refinery. The difference between each brand is the additive package the refinery adds at the end. It’s more important to go to a gas station with newer pumps that look well maintained, so you get as little sediment as possible. And no ToppCat, no gasoline has appreciably more energy content than others. Actually, higher octane fuel is actually less energy dense than regular because of extra detergents and octane boosters. Octane boosters don’t add energy, they just make gas more resistant to knock.
