Yep, I have. I tried a fill of GC in the Audi and also did RP 0w-40 over a couple OCIs. As for cost, believe it or not, the Delvac Elite 222 0w-30 might even be a tiny bit cheaper than the 5w-40. Cost certainly isn't a big deciding issue between those two oils. In that case, I rationalize it by starting TBN.
