I don't want to be 'that new guy' that asks a bunch of annoying questions because he's too lazy to read the threads where the question has been addressed 33 times already. So I read through all the sticky threads int eh oil section and the first 2 pages of other oil threads and still wonder one simple basic question...
What specific oil should I use?
Based on all the tests people did with Blackstone, it seems MKIII owners have great success with German Castrol, but several like Amsoil too. Royal Purple seems iffy, but I am surely open to anyone's testimony of success using RP.
Some basics specific to me:
I live in San Diego, CA - so it's never freezing here and usually quite warm.
My car: 1991 Supra Turbo - 5spd - 68,000 miles. 7M-GTE. Owner has used synthetic since the 2nd oil change. I don't know what kind of synthetic, meaning I don't know if it was group 3 or group 4/5 but I suppose I could find out.
Here is what I'm thinking (without running any specific tests on my oil).
Use either Amsoil or German Castrol 5w30 every 7-10K miles and I should be in good shape.
Am I off base with that mentality?
Thanks very much!
