Reviews of VALVOLINE parts For Business

I waited 9,000 miles to change my oil most recently (with 36,000 total on my VR6 Jetta). The oil is Valvoline 5w-40 synthetic, which I buy from my local NAPA who now stocks it - finally. Bottom line - oil was still in very good condition - still suitable for further use - viscosity still well within 5w-40 perameters @ 14.1. Trace metals ppm were amazingly low for 9,000 miles of use.

I like the Valvoline synthetic. I've tried Amsoil. It was ok, but not any better than Valvoline. BTW, Valvoline meets more specifications than Mobil 1, so I'd stick with Valvoline.
