Hi all,
I'm new here and have lots to learn. I've owned a US-spec E36 "M3" (actually a 328is but everything has been swapped to M3 except motor, has M3 cams, M50 manifold, software, etc) for over a decade now and have used synthetic oil done at around 10k km or 6k miles. I don't drive the car much so I've gone up to a couple of years between oil changes.
In the past, I've used 5w-30 Mobil1 or 5W-40 Catrol Syntec, Castrol Edge w/ SPT (I think the "Syntec" was renamed?) + Molyslip, and LiquiMoly + Molyslip. I'm sure you guys know this but "Molyslip" is a smaller company and have been told its "oil supplement" is similar to LiquiMoly MoS2. The car spent most of its life in Ontario, Canada but was only summer driven. Now I have it down in Southern California, so temperatures are actually comparable, going a little hotter depending on how far from the coast.
Apparently the E36 only switched over to synthetic even being recommended over conventional in 1998-1999. Is LiquiMoly overkill for this car? Can I just as safely go with a cheaper oil? What do you guys recommend in 2025 for a 90's "classic"?
Thanks!
