ive been using royal purple fora while now and have had no problems.

 

isnt that the green stuff? Heard about it, bet ill never see it local. I usually use 0w40 and i think i might switch to castrol 5w40 or the Q power for turbo cars 5w30 when my car is built. That is after i run sh!ty dyno oil for 100 and then 250 miles first

..... True German Castrol. Hard to find, but recommended by Bob.

And it's 0W30 and the Audi recommends 5W40 I believe

 

it just needs to meet the 502 requirement, it doesnt matter what weight it is. There are a few 5w30s that are approved so i wouldnt be surprised if that 0w30 is either

 

Entire list of approved oils here

They probably make more than just 1 weight. Its the hard part of finding the German oil to begin with locally.

 

Nope, the only "Made in Germany" Oil by Castrol that you can buy here in the states is the 0W30 formula.
It does work GREAT. I have been running it in my 06 Honda Si and gained about 2mpg and my wife is running
it in her 07 Nissan Maxima with great results. They only place the sell it here in Indiana is at Autozone and even
they don't have it all the time. I also have them put away a case as soon as they get some in because they can't stock
it for very long. It sells out quickly. It's a bargain at $6.99 a quart since it runs about 18-20 Euros in Germany which
at todays exchange ratge is about 27 USD.

 

^^^ why are all the other TTers in INDY and not FORT WAYNE! LOL

 

someone just joined here from Fort Wayne if i recall correctly

 

oh crap. i use mobil1 fully synthetic 5w30, the guide you linked cincy doesnt have Royal Purple.

also they dont seem to seel 5w40 around here (well they do but i have to drive the equivalent of an oil change b4 i find it) so i settled for 5w30 ...
