Can you use synthetic oil in old cars? Can synthetic oil cause leaks?
Sponsored by Mobil 1 motor oil - You can find Mobil 1 synthetic at a wide variety of retailers and service stations near you. bit.ly/2FOBrVJ
We’re tackling many heavily debated subjects about motor oil in this video and learning how specially formulated motor oil can help new and old engines add more miles to the odometer! Can you use synthetic motor oil in old cars? Can synthetic oils cause leaks in old cars and engines? Where did the idea originate that synthetic oils are not compatible with old engines? If your car is consuming a lot of oil, should you use a thicker oil grade? Finally, when should you use a high mileage oil? I spent time discussing these questions and more with Mobil 1 engineers. Watch for all the details! #Mobil1Partner

    Tbh the video is in most parts right, but there are some specific Motors like the M113 from Mercedes which are known to have problems eexclusively due to synthetic oil. Always make sure to inform yourself befor changing your oil.

    Me and a few mechanics we knew we're blending oils before came out as a durablend mixed and as engine builder mechanic machinists, I found that engines love durablend the moving Parts love synthetic but the piston Rings seal better with oil durablend is a great option high mileage is good with an engine over a certain amount of miles

    Well I guarantee you can't use synthetic oil in old cars I know that for a fact I've been working on old cars for a long time there is detergent that cleans the inner part of the car when it drives that is the worst thing for new old cars because they're not designed for that type of oil the only oil you should be putting in an old car is Rotella T.....

    Yeah, yeah yeah.... So technically speaking u stuck to the script, told the truth and yes your correct on all fronts. Curious though.... Would Mobile have coughed for the oil if you had a slightly different account. I mean really, at the time synthetic oils came out I heard the exact same account in the Anyway the thing that I'd like to point out is that these oils are made and developed in Europe where the weather is very different to Australia drip or behave in have different properties in different climates and to be taken into account when selecting a motor oil just as much as this state of your engine. I personally find that I'm changing oils and filters a lot more and costing me more when I use synthetic oils regardless of the condition of engine.! So is a ploy in part so motor oil companies can ensure the people buy more of the product. IT'S STANDARD BIG BUSINESS 101!!

    Question: Why doesn't my local petrol station no longer warn me not to buy a Synthetic oil (I always wanted Mobil 1) for my old car as it would cause my engine to blow up? Answer: Because they now only sell sandwiches, hot drinks etc rather than a range of oils, or any oil at all. [So I buy my Mobil 1 from an on-line supplier]

    Always enjoy your videos. Unfortunately, this one didn't touch on engines with flat tappet cams.
    My understanding is the pre-roller cam engines need an oil with a high Zinc content, do to the two flat surface, metal on metal contact. Lots of options on the topic, but it does seem that the motor oils available with a high Zinc content tend to be conventional.

      Shoot. posted too early... 1 was 87 ford 2.3 another 80 ford 4.9 inline 6. I was 18 at the time. And just got rid of them. 33 now and I've pondered why from time to time. Best I can figure is they weren't maintained properly by previous owners had deposits holding rings to cylinder walls and new oil cleaned it out.. I don't have hate towards synthetic oil but what I took away from the experience is if your "new to you" 30+ year old engine has a questionable past, and you can't afford a rebuild, stick to conventional. That hasn't failed me yet

    Well I have a classic mini with a moderately tuned engine (90bhp vs 63 out of the factory), the engine and gearbox share the oil. I put 20w50 castrol classic because putting synthetic thick oil makes for a strange shifting experience. From what I could gather, synthetic is just too "good" for that gearbox and synchromesh have hard time doing their work with less friction when the selector fork is pressing on them. I guess it may be specific, but ask old folks, sometimes they know a lot.

    Old Engines did not have catalytic converors so a high Zinc content was not a problem. With the Catalyst the Zn has a detrimental effect. In the case of say a CVH engine the hydraulic tappets are flat, as in old Subarus, and so the the cam, valve gear wear with the newer oils. That is why a ZInc rich oil, or additive is recommended with classic cars.

    I'm a retired lubrication Consultant and Synthetic engine oils aren't created equal. While the synthetic chemical makeup will last longer but the viral additives wear out and breakdown. The problem with many synthetics is the oil blenders use conventional additives and as a result should be changed as often as conventional oil. Lubricant manufacturers make changes often making it difficult to keep up with all them.
    Engine oil such as Pennzoil, Quaker State, Valvoline and Kendal has been bought out by big oil companies and the CEO's make bonuses by producing profits not selling a quality product
    I always preferred the Lubrication Engineers lubricants. They will cost three times as much but will last at least three times as long, the additives are the most supreme available. Older cars owners be warned it cleans the gunk left by the previous oils, it will plug breather caps, simply change them if you see oil usage. As it cleans your engine you could see more oil consumption but over time it will subside. My old truck used to use a quart every 500 miles now I get 2,000 miles. In the long term it saves you money if you want your vehicle to last a longtime.

    Albeit recent price drops, synthetic oils are still more expensive than conventional oils. For my '97 CR-V with close to 1/2 million kilometres (300,000 miles) on the roads, it just doesn't make sense to use synthetic as I've used conventional oil, mostly 5W30 Castrol, and now high mileage conventional oil with age-proven results.

    We know a person that bought a 1994 vehicle with about 160, 000 miles on it. He checked out that vehicle very closely before buying it. IT HAD NO OIL LEAKS ANYWHERE and ran good. He bought it and changed the engine oil and filter using 5-20 fully synthetic oil and a recomended synthetic type oil filter after approximately 2000 miles of use later.GUESS WHAT?? It started leaking oil from the engine oil pan gasket and the engine rear main seal about 2 months and or approximately 1000 miles later. THERE HAS TO BE SOME SOME EXPLANATION FOR THIS HAPPENING????

    Had a 81 Firebird and used 10w 30 Mobil 1 this was in 1988 . I changed over because a friend suggested it. So I change the oil and filter started the car. Holy hell ,the engine rattled like it had no oil. I had a friend take me to the exchange and get more oil ,pennzoil 10w 30 ,went back drained the Mobil 1 ,put on a new filter and the pennzoil started up no problems. I saw several people use synthetic in the 80s and 90s in General Motors cars and they all leaked like a sieve. They weren't leaking before! My Dad had a 92 LSC mark 7 and at around 25,000 miles someone convinced him to change to Mobil 1 and within 5,000 miles the car was leaking and got worse mileage . I had him switch back and within 2 oil changes (6000 miles) the leaks mostly stopped but not completely. It was common knowledge in the Mustang 5.0 community not to use synthetic oil, those who experimented had the same problem as my Dad with his Mark vii, that car had the 5.0 HO motor as well. You might be able to change over the last 15 years or so to synthetic but American cars from the 80s and 90s didn't like a change to synthetic after they were used to a conventional oil. Just my experiences.

    I think I've tried using synthetic 10W-30 oil in my car that has a mid-70's 350 Chevy engine in it several times for one reason or the other and both times it has caused it to start using more oil than normal. I normally use the 10W-40 oil recommended by GM so it could be the viscosity difference, but the only way to test that would be to use conventional 10W-30 since synthetic oil doesn't seem to come in 10W-40. It's easier just to keep using what the manufacturer recommended.

    funny I was a pump jockey when Mobil one came out and at that time the manufacturer said do not mix and it may cause problems if used in older cars. Look it up. Reading is fundamental.

    Had a old galaxy 500 back in the 1970s that burned a quart per 100 miles. I just used my dads used tractor oil which was years old and white with sludge. I’d get the car down to 120 miles per quart:) ahh, the good ole days😂 by the way, the quarter panels were half gone from rust:)

    I put synthetic oil in a 2006 equinox with absolutely no leaks at all.....within 2200 miles, oil was leaking from rear main seal,front timing cover seal,and around the sides of the oil pan.....pouring....not a little drop.....so I determined the seals had gotten hard over time and the sealing ability was not good enough to seal off the more slippery synthetic oil.....i switched back to conventional high mileage..... still leaking....it had 99000 on it when I switched.Big mistake...now I gotta replace seals that were completely dry before the switch.

    can you check and see if there' s any vegetable oil you can use in your 2 stroke chainsaw so your not breathing in pertroleum fumes all day. I'd rather inhale vegetable oil. might be healthier. inhaling chainsaw fumes prolly makes you age faster like smoking does.

    Just have to match additives that the engine thrived on originally. Some stigma is reflective of backyard engine builds and not properly setting up all parameters on initial start-up/brake-in properly. Yes, classic engines with flat tappet cams do thrive and require high zink especially on start up. The same folks that wiped out a cam in an FE series motor, were cranking it dry several times before it fired. Operator problems a lot of times. And don't blame oil for the late 70s through the 80s murdering your engine/ cam. Let's face it, those engine were trash.

    I wonder if Mercedes-Benz has changed their recommendation not to use synthetic oils in the m198 3 l engine used in the 300 series cars of the 50s

    it's difficult to find information about what oil to use in high ambient heat temperatures, like in the south were temps exceed 100 degrees Fahrenheit. especially air/ oil cooled vehicles.

    I have an 07 Lexus I bought new. It only has 33000 miles but the last time dealer service it, they put high mileage blend. Is that good, bad or ok? Thanks in advance for any opinions.

    Most of your "Full synthetic" oils start with non synthetic " dino" oil as the base. Was not like this years ago, but with all of the cost cutting going in this world its the case. This includes most but not all mobil 1 oil weights. Only amsoil and a few other manufacturers start with 100% synthetic oil base. It's a FACT.

    While you are at the mobile one lab, ask one of the old-timers why mobile one was not compatible with piston engine aircraft engines.
