First off, wanted to let y'all know that there seems to be plenty of M05 and M06 Gold German Castrol at the Autozones around Dallas - the one on Inwood, the one on Garland Road, and the one at the corner of Kingsley and Plano Road all had it this weekend.
In my search for a single oil that will perform well in both my LS1 Camaro and my V8 BMW, I have decided that the German Castrol is it.
The BMW calls for a 0 or 5 or 10w - 30 or 40. It has been run with 5w-40 Castrol Syntech from 62K miles to it's current 73K miles. I presume this is Belgian Castrol, since I think that's the ony 5w40 Syntech there is. I liked that my BMW shop put 5-40 in it, because it's hot all the time here, but I think I'll be fine with the 0-30 since the GC is closer to a 40 weight oil and the factory says 5-30 or 0-30 is fine for all temps.
The LS1 calls for 5-30 and has had a steady diet of Mobil 1 5w-30 for all of its 130K miles.
I went on a little treasure hunt for green German Castrol, while I'm reasonably sure that the newer Gold GC will turn out to be just as good if not better, I couldn't resist the temptation of the Green. I found enough for several oil changes in the BMW and the LS1, and will probably do a few oil analyses before and after a switch to gold when my stash does run out.
Interesting observations from the hunt - the AutoZone on Singleton (West Dallas, home of lead smelters and what not) had a full rack of 0-30 Castrol Syntec- but ONLY the really old Made in the USA 0-30! And at least one person asked me if I worked at the AutoZone when they saw me sorting through a bunch of bottles I had pulled off the rack and set on the floor
