Sample 2 was 0W40 Mobil FS and Sample 3 was also 5W30 Valvoline R&P but just a 2,500 mile run. Wear numbers look really good for this run. I don't put much on the appearance of the oil but this stuff looked almost as virgin coming out as it did when it went in. This OCI had a bunch of highway miles just before the sample was taken when most of my miles are usually in town.
