Huh? I have a '95 Volvo 850 Turbo. Not sure what you mean by notice any difference. There are a few benefits in using full synthetic oil... 1. You should get about 2% better gas mileage. That is a $2 savings for every $100 spent. 2. You should not have to change your oil as often. So, instead of changing your oil every 3,000 miles, you can change every 4,500 miles (on average). So you save money in oil changes. 3. If your car is turbo, it helps your turbo last longer. 4. Your engine should wear a lot slower. 5. It should clean the inside of your engine better, less risk of sludge build up. Not so much what you notice, more of a long term benefit.

Synthetic vs. "regular" engine oil is just the latest controversy for engine lubrication. Most of you are too young to remember the even greater controversy between detergent, non-detergent, multi-weight and straight weight oils. Back in the day when detergent oil became popular what Eric said about old engines and better oil was really critical with straight weight oil. I saw it happen in 1964 when a friend had a 1956 Pontiac V8 that ran OK buy had a bit of lifter clatter. He poured in a bunch of STP which was the same as switching to detergent oil. The engine literally came apart. We pulled the pan and found most of the piston rings in there. The only thing that had been holding that engine together was all the carbon from years of straight weight non-detergent oil. A guy I worked with in 1970 had a 1958 Chev 6. He was a firm believer in straight weight oil. He went to work one afternoon in Minnesota. By the time we got off work at midnight the temperature had dropped from 45 degrees to 10 degrees. He didn't get that car to start for a week. The same thing happened to a neighbor with his 1968 VW Microbus. I have been using synthetic oil exclusively for at least 30 years. Besides my cars I use it in my lawn mower and snow thrower. I put synthetic in several used vehicles I bought with 20K to 40K miles and I never noticed any negative effects but I also never had any engine issues or performance problems. I usually drove all those cars well over 100 K miles. I used to do all my own oil changes but in this stage at age 74 and able to afford new cars I let the dealer do it. That's another issue. I always have my vehicles served at a franchised dealer service department.

The best explanation I have heard on the topic.

This is the best video on synthetic vs Conventional. Thanks Eric!

I agree Eric. I learned to changes engine oil when I was 8 years old with my dad. every winter and for the summer.

Hey Eric, thank you for sharing your knowledge and expertise!

I have owned and maintained my cars for over 50 years. I have driven every car I owned to over 100,000 miles and one to 350,000. I have never had a mechanical problem with any of my engines.

+Bronco Billy agreed. i try to preach the gospel of the sub-5k oil change to all my friends with new cars and "8-15k miles oil change interval" engines/oils. Even if your oil can go that far, its not always about the oil. its about getting eyes on parts of the engine you never see and potentially catching leaks or other issues before they leave you stranded somewhere and a huge repair bill. I also firmly believe in doing as much service work as you can yourself. the better you know your vehicle the more quickly you catch on to problems like that. I've never had a vehicle break down, and i have had some horrible old rust buckets out of necessity. its all about keeping up with regular basic maintence, oil, cooling system flush, check trans fluid for discoloration at every oil change and drain/fill the moment it starts to turn brownish, rotate tires every other oil change, inspect brake pads and rotors for wear while doing it, etc etc. if you get used to doing it you can do it yourself in the same amount of time it would take you to wait in a lobby at jiffy lube. lol

If sec 3 has Distillates, petroleum, solvent refined heavy paraffinic it has class 3 oil and is not 100% synthetic. Note - Full Synthetic on the label is a marketing term and there is no way to tell what is really in the bottle without checking the MSDS. Unless it says 100% Synthetic on the bottle, it may not be 100% synthetic base stocks.

Nothing is ever machined to absolute perfect specifications, so the first few oil changes on a new engine are extremely important. This is the time when the engine first operates and deals with any minor inconsistencies that may exist in tolerances. This minor "break in period" will produce contaminants that end up in your oil and filter. Getting rid of those contaminants, with an early oil and filter change will go a long way toward the eventual longevity of the engine. Most 2-stroke and 4-stroke small engine manufacturers recommend that the first oil change for new equipment should take place after one to two hours of run time.

Sir, you made good points. Great video. Thank you Sir for your honest review.

Spot on eric, I always recommended my customers not switch to synthetic in a high mile engine, because of the seal issues. Even though, I much prefer synthetic.

Hey Eric, I'm a chemist, and the best way to talk about viscosity is whether you can push the fluid around, or whether when you step on a puddle of it, it splatters. It's about how the liquid bonds to itself as a puddle or a drop or a pool. Flow and viscosity are not the same parameter (that is, scientific measurement), but they are closely related, and they correlate almost identically, meaning that if you have one, you have the other doing the same thing.

I'm in total agreement with Eric, and I've been working on cars for 35 years (so seen many generations of cars). I would add to the comments of change your oil - always check the oil level and know where you are. Many cars run around 1-2-3 quarts/litres down and that often coincides with internal engine damage. You may not be leaking oil, but burning it. Always check levels. I run regular oil in my BMW (which shocks the German parts distributor). I haven't damaged an engine since I let one run low of oil in my teens. I also saw a motor recently which had shrapnel blow through the block (also BMW....modern with no dipstick)...he had ignored an oil light!

Phil Nicholls ..I avoid German cars like a plague! American or Japanese only ..they run forever when maintained properly.

Awesome video. One of the things that I read about synthetic is that the synthetic oil is refined more, and that the molecules are therefore of much more uniform in size, and on average smaller than the molecules in conventional oil. That's why the viscosity of synthetic and conventional can be the same, but synthetic will leak more through the same seals. Synthetic is engineered for tighter tolerances in newer (roughly post-1990) cars, but works just fine in older cars. However, conventional motor oil may not work as well in the newer cars because it's more prone than synthetic to sludging. An example of this is the Chrysler LHS 2.7L V6. It was engineered with smaller oil passages because synthetic was recommended for the engine. Customers bought the cars and the engines ran great, but as soon as they started dumping conventional oil into them, the engines sludged up and started seizing like crazy. My sister-in-law had one of these cars. She ran synthetic in it and the engine ran fine for years. However, she later decided to make a couple of ten-hour-long trips and without doing an oil change. She's the kind of person that just doesn't pay close attention to maintenance like that. Example: the oil pressure switch went bad and she just drove the car for two years with the idiot light on. Soon after her long trips, the water pump in the car went bad. I ended up changing out the water pump and the timing chain for her, and had to change out the oil and filter at the same time. Lo and behold, the sludgiest oil I had ever seen! She ended up selling the car to a buddy of mine for $400 (he was going through a divorce at the time and couldn't afford more). That was also when we replaced the oil pressure switch. We drove the car for a week and changed the oil and filter again. Its condition was improved to "nasty." The car ended up running for about another year. Then the engine seized (luckily the buddy got a little cash that same week and upgraded to a better car). Long story short: Sludge will kill newer engines (and some are more prone to this than others). Synthetic was developed especially to combat this problem. Changing oil regularly and using what's recommended is a good thing. Ignoring oil changes will absolutely murder engines.

Thank you for making these videos. I love your prowess. Off to change my oil.

I just changed my old synthetic oil for new regular oil and there is definitely a difference when its cold. The engine cannot put out as much power until the oil warms up and flows easy. My average mpg has also taken a hit. Its doing about 1/2 mile per gallon less now. I think the extra you pay for synthetic oil is well worth it as you will probably get that money back through fuel economy.

Thanks for the pro tip. About to try synthetic at the end of the year when I hit 95K. Original owner here and been using conventional

I put honey in with my oil and get good results - exhaust smells great as well.

Eric : Thank you for your videos It's a big help especial for sharing your wisdom and experience. God bless you.

Hey, man. I love your videos. Very articulate, and very easy to follow. Thank you!

In a comment below, somebody said "If you listen to Eric, he says that old oil break down and become too thin. I listened to Eric and understood the opposite. Old oil become more thick, as in become mixed with burnt hydrocarbon (which become acidic). The acid dissolve thin layers of metal anywhere in the motor which then mix with the oil. These microscopic pieces of metal are abrasives. The old oil is like a liquid sand paper. It makes every moving part rubbing harder and accelerating the destruction of the motor. The acid also attack the rubber, making the seals hard and brittle. If you buy synthetic oil 10W30, for example, it will appear the same thickness as normal oil with the same rating of 10W30. The thickness is the same when pumping thru pipes, the oil sensor detect the same pressure, the only difference happen at the point when two parts are in close contact and moving. Synthetic oil is a "non newtonian" liquid. Look at videos where people can walk on a baby swimming pool filled with corn starch, but start sinking as soon as they stop running. Synthetic oil flow smoothly, like water, at the exact points where two metal objects are moving, like in the bearing. This save gas because it resist less to moving parts. This "non newtonian" easy flow happen even when cold. I presume that such oil flow thru damaged sealing because of slight motion created by the vibration. If the seal flex a little, the oil may become temporarily more liquid at that point like it does between moving parts. Over time, it keep creeping thru cracks, get trap in portion of the gasket then resume when vibration make it liquid again.

typically synthetics- being man made are made from a smaller molecule and thus more easily escape past rings, seals and gaskets. the trade off is as said that the synthetics have better flow rates for lubricating, cooling and washing carbon out of the engine and into the sump. synthetics also being made made from smaller molecules, penetrate the micron surfaces of metals better than petroleum oils and thus clean, lubricate and cool better. synthetics- being man made- not from carbon base oils, do not break down into a carbon form. certainly carbon will blow past the rings but the lubricant itself will not digress into a carbon form like petroleum oils. if you take note of any engine that has been run ONLY with synthetics, they don't have the gigantic carbon flower growing around the intake valves that disrupt airflow into the cyl. it may have some, very little, but is substantially reduced in comparison to petroleum oils. this helps your engine make more power over the long haul and increases it's overall efficiency through airflow characteristics. if the manufacturer wanted a big carbon blob on the intake valve- they would have made the engine with a big blob on the intake valve. synthetics having no carbon in their base also do not pollute the atmosphere with carbon like carbon based petroleum based oils. crankcase gases that are reburned to vent case pressure may contain some carbon from combustion bypass gases, but not from the oil itself or additives evaporating at high temps.

I work in as a factory Maintenance technician. During our training with our Oil supplier reps he stated that Synthetic oil is still dino oil but just refine to a higher quality. The refinement makes all the molecules similar in size. Which allows for less friction and lower heat buildup. In turn less deposits. Most oil brands also add their own proprietary blend of additives four anti-wear and detergent purposes. But whether conventional or synthetic is still refined from crude oil.

thanks for that last edit of your oil! great channel eric!

This answers my questions! I do not use synthetic and will stick to my Castrol….I appreciate this info! Oh yes, I have a Chevy HHR 2010 and have 110,000 on it. Yes, changing your oil is the key!

05 gmc yukon 280k miles cheap conventional oil from day 1,the engine doesn't burn a drop of oil all original seals except oil pick up o ring ,change your oil people even if it's olive oil hahaha

engines that are not stressed by heavy loads or speed tends to last longer, most specially bigger engines.

I always change oil every 3,000 miles or 6 months, whichever one comes first. Sure it is probably overkill, but for what it costs, peace of mind is priceless. When I purchase my next vehicle with low miles I will go with synthetic. In the meantime, I use regular 5w30 for my 1996 Ford Thunderbird LX V8 and change it myself. The car has 140,000 miles and the reason I don't switch to synthetic goes into what this video talked about. I don't want to fix something that isn't broken and risk having anything leak. Anyway, it is what Ford recommends for my engine and as far as I know it's the same oil the previous owner used. Btw, some people may argue with this, but I wouldn't go to any express oil changing business. I'm not bashing anyone that works hard at any of these places, but it only takes that one person who doesn't know what their doing to destroy your vehicle. Take care folks

No reason to change oil on a time interval basis. It doesn’t break down just sitting there. It’s not milk!

Eric is a great mechanic ! Great video !! Enjoying watching your video !!!

The best ever explanation of oils, I have ever seen. Just the facts and mechanical experience, that was outstanding Eric. Many thanks 😸🍻

My engine does exactly what he says. Synthetic leaks out past the rear main seal even though I had the seal replaced by a well known Honda specialist. A good conventional motor oil changed at regular intervals is fine by me and no leaks!

I totally agree with you. here in Russia everyone is crazy about synthetic oil. they say you can't blend synthetic and conventional, can't eveny blend synthetic with synthetic if brand is different. my VW 2011 runs on cheap oil and it's OK. 9O OOO miles. but I keep argueing with my friends.

+Vitaliy Kanunnikov your friends are wrong. we have regular and synthetic oil blended together and sold here in USA. the important thing is to change oil and filter every 4-5000 miles no matter what type of oil you use. this is what prolongs a motors life.

elr2141979 lab results show that a synthetic blend will be fine for 8-15k miles. If you want to go 18-35k miles, then you need a fully synthetic oil and perhaps a filter swap near 17.5-18k miles.

this guy is living legend any problem you had you well find a video for him talking about it

Thanks Eric you always give us clear answers! You are so right!! Thanks Eric!

my old engine seems to prefer synthetic with a little Lucas honey..Call me crazy but if I get generic it blows smoke..get full synthetic and Lucas and it is fine

Conventional oil has been around for a hundred years. Just change the oil and filter at the correct intervals and you will be fine.

By far the biggest difference between normal and synthetic oil is how their viscosity changes over the few thousand miles driven on it. If you watch the engineering explained synthetic video he pours brand new oils and then used oils side by side and you can see that even after being driven on for thousands of miles the synthetic still flows like new and the conventional has a much different flow than new because it broke down so much. Synthetic has the ability to retain an effective viscosity for a much longer amount of time, so long that the limiting factor on it's life becomes blow by contamination which means you can go a good 50% longer oil change interval with synthetic on average depending on your driving patterns. And because it holds its viscosity so well it's the perfect thing to fill up an old Briggs motor with, the kind of thing that you don't really change the oil for years on. One of those things would go forever with a pan of synthetic.

sirgallium You are correct re the flow of conventional oils changing as they wear. But it's the cold state that changes not the oil overall. The additives that give the oil it's multigrade characteristics and ability to flow when cold break down so the oil returns to it's base stock viscosity. This doesn't happen with the synthetic because the base is essentially made multigrade. When I learned this it explained why my diesel engine progressively cranked slightly slower in the morning as the oil aged between changes. Change the oil and it's like the battery has a boost.

Thank You Eric🙂 You have helped me tremendously to have clarity on the difference between synthetic and conventional oils!! 👍👍 Very informative and helpful!! Thanks again!!👍👍🙂

Thank you for your honest information in this video you set me straight on a lot of things and (I know we are always learning) Thanks for posting!!!!

eric, you have to speak your mind and not worry about the technicality's. just say what you know.

You forgot to mention that full synthetics reduce or eliminate oil consumption because of the higher flash rate. Also, synthetics are more fluid in extreme cold conditions. I know about that. Here, in North Dakota it drops to -25F° sometimes and you know when you have conventional oil or synthetic in your gears or motor. There is a major difference. There is 2 Cycle synthetic out there now which has a major benefit with cutting down the smoke. I use Mobil 1 synthetic oil in everything I have. Old, and newer, even my snapper mower. When I used conventional oil in the past, I would get more carbon type buildup and oil consumption. When I changed to synthetic, oil consumption stopped, and things were cleaner. And, I also changed it less often. My retired daily driver, a 2003 2500 AWD GMC Savana has 276,000+ miles on it. It was a daily work van, grossing out at nearly 8,000 lbs. Didn't use any oil, with the full synthetic. Changed it every 3,000 miles. I change oil around 3-4,000 miles. I currently have another van I upgraded into and it has 200,000 miles on it to start off with. I'm going to be running a 15,000 mile Fully Synthetic Mobil 1 oil in it to see how it runs. I'll be changing the filter (ACDelco) more often, likely at 3,000 or 5,000 miles. The vans I drive are grossing out at nearly 8,000 lbs, are kept running all day sometimes, and I travel around 16,000 - 20,000 miles a year. People will say I'm wasting money changing the oil more often even though it's synthetic but, consider the cost of replacing the engine, and you'll find out quickly what's wasting money. Wasting money is spending money on cigarettes, chew, drugs, and booze. That's a waste of money.

Hi Eric. I just want you to know I'm very appreciated for your KZread about car oil. Appreciated. I'm Terry

Just got rid of my '91 F-150, used Wal-Mart Super Tech conventional oil, now driving a 2015 Ford Fusion, so I wasn't well versed on synthetic oil. Thanks for informative video.
