Amsoil 5w40
Red Line 5w30/5w40
Royal Purple Racing 41
Mobil 1 0w40
I've done 6 oil analysis' on my engine since installing a cam at 4K miles. It showed much better wear numbers with a thick 30W and 40W over a thin 30W like Mobil 1 5W-30.
Add Mobil 1 5W-40 Turbo Diesel to the list......

and how do u tell the German Castrol from other Castrol

Hehe 45 yo.. My mom's got almost 20 years on that and I swear on my old 94 z28 a4, she nailed that gas to the floor every light and stop sign she got the chance 
Had she driven that thing 24/7 it woulda had 45k miles on it that were like 300 laps on nascar hehe

can you get 5w40 from wal-mart? if so i'll go with that then. not trying to hog the thread here but what do the numbers mean i think i'm pretty sure what they mean but i would like to hear it from someone else. thanks.
Well I was going to get the syntec 10w40 since NO ONE around here had the 5w40 m1 or anythign else for that matter that was fully synthetic and better than 5w30.
Luckily I saw a thread here mention somethign about an amsoil dealer that was a memeber) so I tossed em some business

Uh oh... seems M1 5W-40 T&SUV is being discontinued:
http://theoildrop.server101.com/cgi/...;f=35;t=000912
I hope wally world will carry the supposed equivalents, Turbo Diesel 5W-40 or Delvac 1. If not, will have to see if the new Castrol European Formula, which is supposed to be the replacement for the green GC, gets wider distribution, making it easier to find.
