Just curious. Bought my car a few weeks ago and i would like to change the oil in it, just curious to what kind of oil you guys use?

 

was running amsoil 20/50 zrod but switched to 15/50 dominator no real change in performance difference

 

Which one lasted longer?? Meaning when you changed oil again, which one of them do you think you wouldn't mind reusing just in case?? Thanks!!

 

Motul 300V 15W-50, will never use anything else, ever.
the oil you buy on the shelf is the same oil that's used in 24 hour Leman's cars... what other company does that?

 

I'm a fan of royal purple...but I change oil every 2 thousand miles so I can't speak on longevity

 

Idk which lasted long but I change my oil every 3k. I'm looking into sending a sample out for analysis. I'm curious how they both break down and what not

Where do you buy it from?

 

Mobil Delvac 15/40.

 

Valvolene VR-1 Synthetic 10w30 for the past year.

The oil sample says gasolene but was actually E85.

E&H Motors, Pukekohe, NZ

 

Another for Valvoline VR1 10-30 synthetic race oil. Keep in mind you're asking an incredibly broad question. Some people have already posted about race motors, some of us have the car solely dedicated for track purposes, some live in FL and some live in NH. What's right for some isn't right for all.

 

Johnson&Johnsons Baby Oil.


I had been using Penn 20w50 then I switched to Valvoline VR1 20w50.

 

Amsoil 10w30 on BBK, 10w40 on Black, and after break-in on 2.4LR I'll run Amsoil 20w50.
