Wouldn't it be better to run 5w-30? I know the first number is it's weight cold, and the 2nd number when hott. But I know 5 vs 0, 5 would be alittle thicker when hott right?

Funny because I just posted this exact topic in the internal section (whoops). Anyways, I can't find this oil anymore either, and i'm do for an oil change. I have tried so many oils, and german castrol eurpeon blend is by far THE BEST, period. I have compared it to royal purple, amsoil, redline, and mobil 1, and even sent them all out for testing after I used them. GC euro blend came out on top every time!
GC was the only oil that didn't burn, and now it's gone....

The 0-30 is the only one made in Germany. Some Autozones still have it. You might want to have that store locate you some and order it in. I may go back to it, but Mobil1 is great as well. Those oil findings are posted on www.bobistheoilguy.com and were sent to Blackstone Oil labs.

Im running ams oil series 2000 0w30 in my 99 z28 and i have 103K on the car. I love it and i am not burning a drop. Plus i have the Ams Oil EAO oil filter so i can go 15,000 miles on an oil change under severe driving conditions. Ive tried Mobile 1, Royal Purple, Castrol, and Vavoline. Out of all of those synthetics Ams Oil was definitely my favorite.

I could ship some 55gal drums of Castrol 0W30 over for you guys 
I prefer the Castrol 10W60RS, Castrol says this oil is also used by Mercedes for their Formula1 engines and these things rev up to 20000rpm so I think you can't go wrong with this type of oil, never seen it in the states though...

Are you sure of your sources???
From my knowledge most of the Formula One engine are using a monograde straight....and the common value would be 30!!!!
But if you have the info directly from F1 engine builders or from a F1 engine provider...I would like to understand if it's real or marketing.
