Elf has just released a new product, Solaris LLX 5w-30 which meets the latest VW 504/507. http://www.turbofrogperformance.com/Products/Engine/ELF_Oil.htm I guess that this is the first "low SAP" lubricant in the U.S. (correct me if I am wrong) The new VW 504/507 specification will replace all 502, 503.01, 505, 505.01 and 506.01. This ain't no cheap oil. I've heard that new VW/Audi 2.0T FSI and 3.2 FSI engines in Europe mandate 504/507 oil spec, but the same engines in the U.S. will be still using 502 spec oil. Anyway, I guess choosing a right spec oil for VW (gasoline and diesel) and Audi owners.
