Each region has transportation and storage additives specific to their own demographics and weather. The German cars are designed to run on better quality fuel overseas so any problems w/ North American lower quality fuels really show up with those cars!
I've used only Chevron for the last 9 years with no issues!! Shell is indeed on Audi's approved list so they should be ok also! Just my 2 cents!
