My brother bought this Diesel Gate buyback for his new long-distance commute. About 160 miles a day, mostly highway. Cool car, 6 speed manual. I was looking and there wasn't a single 5w30 on the shelf at Walmart that meets this VW 507 spec it calls for. He ordered Castrol Edge Professional OE, 6 quarts for $67 on Amazon. There has to be a cheaper oil on the shelf that will work for this daily? I read elsewhere that Gold bottle OE Edge is the same as the Extended Performance gold bottle, without the UV Dye pre-added. But only the OE claims to meet this 507 spec.
