I was at the stealer last week and chatted with my local xfire rep and he informed me that the 0-40 mobil one will not be available soon in the US. He said that this was a European blend that will no longer be carried here.

Since there has been much debate about using other weights on the forum, he did inform me that 5-40 would be just fine for our engines but nothing more, and that synthetic is the only way to go with these cars.
