I know this is one of those ?s that never ends but always comes up,what oils are you guys and girls here running in your cars all the fluids etc,i was going to do a full change this weekend ,i have always used mobile one in the sy and never had any issues 15/50 in the engine and i think 80/90 in the rear.I know some guys say that the mobile one has the posi additive in it maybe?

Mobil 1 15w50 since 1987

Mobil1, to the best of my knowledge, does not have the additive in their rear diff. fluid. I've always had the best success with the GM additive.

For oils I've been running Shell Rotella, but now that I'm set up as a distributor for ZDDP+ I'm going back to 5w-30 oils.

PS- Synthetic oils don't like lead contamination from race gas...

I have run Texaco 10-30 in my WE4 since I bought it in 1994... In the 86 T-type, I ran Texaco 20-50 until 2005 when it became very hard to find, and started running Castrol 20-50. I'd try Mobil 1, but I don't have the $$...
