They are "said" to have more TBN modifiers which prevent oil from becoming acidic, volatility modifiers to prevent evaporation. But its better to just change your oil at 5000 or 6000miles. If your engines starts burning oil, you can't have the oil Company pay for it anyway.

[@dielauwen]

Calling it Synthetic came about when Standard Oil -Mobil - ws developing lubricants for jet engines and they found a recycled oil was more resistant to high heat. But Standard Oil got the government to specify first run only conventional oil is required for military engines and aircraft in particular. So to get around the law they renamed it Synthetic and so it has been ever since. You pay more for recycled oil. In 1974 recycled engine oil refiners were wiped out. Fleets used recycled oil to save money with better results than first run oil. In other countries the term synthetic was not used and they continued to use recycled oil which is refined many more times than first run oil allowing longer oil change intervals and superior lubrication.

[@rogerpearson9081]

A lot of good info. Special thanks to Mobil for helping without it becoming a shameless plug for Mobil 1. Of course the real magic is the chemistry in those additives on top of the chemistry in the base oil. Bet we cannot find out as much about how they work. I use a semi synthetic in my 1996 vintage Ecotec and the killer advantage is that it is a 15W 50 oil so the engine is a lot quieter on a cold start while not giving anything away on a 45 degC day. For more demanding jobs the full synthetic is absolutely the right oil. Turbocharging or high revving multivalve thrive on it. It certainly explains why synthetic oil makes engines last longer if it keeps the ring lands clean and lubricated. Apparently synthetics are not recommended for LPG. Don't know if that is still true but back in the 90s I ran a 250 CI falcon on LPG and even then some oils were duds with it while others would run over 8000k and the oil would be like dark honey. I think it was the early synthetics that broke down in the acidic byproducts of LPG combustion. Not sure if the newer ones are ok with it now or not.

I then started using a 10W-40 semi-synthetic oil, as recommended by Toyota, did 5,000km (3,125mi), then changed the oil and filter. I have noticed the oil appears cleaner after a further 5,000km. I think the most economical option is to check the manufacturer's specification, frequency of oil and filter replacement, and adhere to it. Some years ago in Australia (mid-1980's) Mobil decided to use their full synthetic (Mobil 1) in their petrol (gas) tankers, but found the ester content had an adverse effect on their oil seals (swelling, softening, almost 'dissolving' through its detergent properties), to find that a regular manufacturer's maintenance schedule using mineral oil was adequate...

This makes me wonder, if I change my oil at reasonable intervals and never let the oil run low, how important is synthetic oil for me?

[@sunilayya8948]

I can feel my engine running noticeably smoother, quieter and cooler with synthetics. Thats enough proof for me.

[@taylornikii]

I have a 2018 Tuscon and made a mistake of using conventional oil in it one time. When it was almost time to change the oil, the car still had oil in it. The engine sounded fine. With the synthetic oil, the engine sounds worse when it's closer to a change. I have noticed a difference in performance. Tonight I had to go get some oil because the oil light came on before the recommended change. I will be using conventional from now on.

[@billroberts9182]

Full synthetic oil is not recommended in the aircraft engines because it lacks the ability to keep particulates in suspension. Conventional oils or semi-synthetic oils are used. From what I understand full synthetics for small aircraft engines caused a lot of damage and were then pulled from the market. On my engine (Lycoming 160 hp) the oil is supposed to be changed every 25 hours of use.

[@breesej]

YES! Finally a new whiteboard video.

[@RailFanRob]

There is an inherent problem when switching form a conventional oil to a synthetic oil. I as well as other people I know had our vehicles start using oil in between oil changes after making the switch. If you are going to make the switch go with a slightly heavier oil. Example: if you use 5w30 switch to 10w40. That will slow down consumption...it did for me.

[@SurvivalRussia]

I have heard that some crankcase seals and other rubber part on older cars does not like fully synthetic oils. Can you elaborate on that please?

[@buzzyinurface]

He has a video on this. Check his channel, it was pretty recent

[@429thunderjet2]

Naw, Those were the ester base synthetics from 30 + years ago that swelled the seals too much causing issues. The modern formulas of the top premium real synthetics use combinations of PAO with some ester and other stuff to keep the seals pliable. The group III highly refined hydrocracked petroleum based synthetics are formulated to be nice to seals as well I believe. This is basically said, but there is much more tech to it. But so it really is a non-issue today.

[@bobpress1235]

Yessir Mr. Russia- as your cars gets older, all the seals and gaskets shrinks, contract, and rot from wear and age, and when you use synthetic oil because of its lubricious properties you will experience increased leaking everywhere.

[@SurvivalRussia]

[@menguardingtheirownwallets6791]

If you don't live in an area where the temperatures hit sub-zero in the winter months, then you probably don't actually 'NEED' synthetic oils (but synthetics do help prevent 'sludging' in Toyota V6 engines). If you live in a place where it does get really cold in the winter, then you probably should switch to a full-synthetic engine oil as it won't thicken up to a hard paste at -40 degrees.

Synthetic on newer engines i agree, but older engines there was a lot of heat generated on air cooled VW bug. so i would think oil changes at early enough intervals using mineral oil is still a good deal on older engines.

[@ronnronn55]

I have used an engine flush successfully in many of my vehicles. My recipe: 1/3 motor oil, 1/3 diesel, 1/3 automatic transmission fluid. Let the engine run until warm with no load, then empty. The amount of dark color coming out is significant.

[@tacomas9602]

I prefer a quality conventional oil for my old motorcycle and tractors. For my truck, an 04 Colorado, I use a semi synthetic blend of 5w-30 for it. Changing your oil every 3-6k on a vehicle consistently also improves it's life.

[@ryanjindra1988]

Is the oxidation why intervals are mile and time based then? That makes sense.

[@TelmoMonteiro]

It is one of the reasons apparently. Also fuel and water content in the oil may increase over time. At least the water content may increase when the engine is stopped (for a long time it seems). In the context of long time resting engines oil components stratification can even occur.

[@mrtopcat2]

I'm friends with a large fleet owner for over 20 years. He always has used the cheapest oils that he could get. With regular oil changes, all of his (driver abused) fleet vehicles made it well past 250k miles. Needless to say, I don't believe in oil discussions. Oh and I know a little bit about engines too. I have a fully equipped shop at my home garage and have been working on cars for over 30 years.

[@IKhanNot]

Exactly. Did cheap oil changes in our Nissan Sentra for over a decade and the car still runs fine with 216k on it. On time oil changes are more important versus using oil that costs 3X as much. Also, when conventional was pretty much the only thing available those cars still ran 200k to 300k and beyond just fine.

[@sogerc1]

0:01 whiteboard, that a good start ;-)

[@ForTehNguyen]

synthetic is worth it alone to run twice the conventional interval to save time/hassle. Havent even counted the better start up lubrication

[@stephanechabot1175]

Great Video. I understand the advantage of synthetic oil, but would the viscosity curve for a 5W20 conventional be the same as synthetic? The numbers do refer to cold and hot viscosity measurements.

[@prestondeters5093]

It would seem so, but the conventional would require more of those viscosity modifiers and as the temperature of that oil gets hotter and hotter, the conventional oil will thin out much more quickly. I bet you haven't thought about this comment for awhile.

[@David-nh2ho]

I've used conventional oil for years! I always change it 1500 to 3000 miles I've never had a problem

[@kb25j]

Very interesting - thanks. I suppose this is why they say to change every 3k miles or 3 months, then. So, if a car sits around a lot w/out being driven much, does oxidation have much of a chance to occur (beyond the top layer of oil that's always exposed to air, I suppose), or does it still really have a chance to ruin the oil, requiring an oil change even w/low driven miles?

[@QuincyStick]

Firstly those guidelines would be for conventional oil, sythentic oil guidelines are 5k/6 months. That said I've seen oil testing analysis that on 7.5k mile oil that had been used for 25 months, and it still showed NO signs of water absorption or general degredation as opposed to a standard oil change. Do with that information what you will.

[@davidparkes7226]

This is a great story but in real life I have over a dozen collector cars , I have always used 15/40 Castrol diesel in all my gas engines and a dose of GM EOS for good measure , some get changed every 10 years and as I am always playing around with cam and head changes I can see first hand no negative effects from extended changes , also ran a fleet of cube vans of 2000 model vintage same oil changed every 10,000 km after 500,000 plus km engines were showing minimal wear !

it depends on how far you drive if you don't drive your car that much use conventional and if you drive long distances use synthetic oil

[@fowvee]

I can't help but think of the interview with the laboratory technician (possibly lab owner) who has been interviewed several times and asked his opinion based on the results of thousands of oil analysis reports whether he thinks synthetic is worth the cost. His answer is no. He states that the benefits of synthetic oils is mainly displayed in extreme cold temperatures where synthetic flows better than mineral oils but for everyday "lower 48" locations it simply doesn't show a wear benefit. The lab tests don't care what brand or composition the lubricant is. The equipment simply returns a test result.

@@dannydaw59 It’s not a true synthetic by some definitions. In some countries it can’t even be sold as such. Amsoil, Royal Purple, Mobile 1EXTENDED and Pennzoil platinum or ultra are true synthetics. Best economic bang for the buck is Pennzoil platinum with the ultra having a better detergent package but more expensive and harder to find. Amsoil is the best but very pricey so I go with the platinum & Wix or Napa gold filters with vehicle recommended change intervals.
