Are Turbos Hard on Oil?

[Azimuth]

It don't believe it suggests that star polymers are significantly worse. Sure OCP performed a little better for the test but it's still just a test. There are other tests where OCP does worse so it's a constant balancing act between competing objectives. An other thing is that the additive package (High Moly, or avg detergent) had an even larger impact than the type of VII used.

Edit: What @buster has really shown us is that one should not use aftermarket moly additives in your turbo engine unless you change the oil more frequently.

I wonder how moly heavy oils like HPL would fair here.

Probably just fine because they use a larger than typical dose of antioxidants.

I found interesting oil on FB marketplace - Amsoil 10w30 Turbo Formulated API SJ-CF.
API SJ was a popular standard from approximately 1997 to 2001. Is it possible this oil to be 25 years old?

Early 2000's possibly. But suspicious. Any other markings on the bottle?

I hope they eventually manage to build gasoline turbo engines solid like the turbo diesels. I read a Cummins made it to 3 million miles

Nope, the guy posted only this picture and I think asking $20 for the three bottles, somewhere in Indiana.

Yes it is I have bottles similar in my shop I’ll have to pull out to look at but yes that was the labeling back in the day.

I had thought Mine might have been a SL version but this goes back many years. I'd run it to this day be great in a OPE I believe this was a very stout formula in the day.

What is there to be suspicious of?

No one is going through the hassle of counterfeiting 3 bottles of 25 year old Amsoil for 20 bucks.

Are Turbo's Hard on Oil?​

YES!!!

Also recently just did my first oil changed on a turbo DI vehicle (w/around 5000 miles on the oil) and yeah the oil looked a lot darker than I was accustomed to. Also, I am not accustomed to / wasn't expecting the sump to be 5.7 quarts. I mean I happened to have enough oil for that, but still.

Cut that OCI down to 4,000 miles max.

Are turbos hard on oil? Are Florida summers muggy? Is water a liquid at 70 degrees Fahrenheit? Do cows eat grass? Is this post a long drawn out snarky way of saying yes? The answer to all of these questions is yes lol.

Turbos add heat to oil because they get hot oil lubricates them so the oil is exposed to an additional source of heat. That is hard on the oil. Turbos increase cylinder pressure more cylinder pressure more heat in the cylinder and more pressure on the bearings. Which is more stress on the oil. If you are running a turbo engine even under normal driving conditions you should change your oil more often and never run a conventional. If I ran anything with a Turbo I would do 3K to 4K oil changes with every other change I would do the filter.

Diesels are not my wheelhouse. I thought from the info I’ve gleaned about them on here, that the 7.3’s were “easier/better” on oil due to being pre-DPF and emissions systems. No regen cycles and all that?

Regen cycles are not by definition hard on oil, it all depends on how it's done. Cold starts and frequent cold running will be harder.

I wonder how moly heavy oils like HPL would fair here.

If it’s formulated into the oil it’s fine if you’re adding moly additives the high moly count can potentially cause coking long term.

I meant my age guess is suspicious. Suspect. A transitive verb.

I did not read the last 8 pages of responses.

The simple answer is yes. Audi has been using turbos since 1979 and their spec until recent years was 5w40. I would go with 5w40 and for high performance applications 5w50. If you operate in a super hot weather place like Phoenix use 5w50. Get a catch-can. Change oil before 5000 miles.

A wise decision in this thread

I'd like to know as well how HPL would do on the GM Turbo or IIIH test. On paper it should do quite well but formulating an oil to be exceptional in all areas is no easy task.

Just look at the testing data on page 4 that I posted (post#80).
