So, believe it or not, I searched and couldn't find anything in regards to my questions....

1. What Motor Oil are you putting in your RS6?
2. Where are you buying it?

I ask 'cause tonight I went to Pep Boys, O'Reilly, AutoZone and Walmart trying to find 5W-40 for a gas engine (as my manual directed me to buy). I found ZERO options. All 5W-40's I found were for turbo diesels.

I need help right away as my car is low and I don't want to drive it at all while low on oil. Thanks in advance!!
