I've two new cars to maintain. 2020 VW Tsi 1.4 which calls for 0w-20 VW 508.00 and a Mazda 3 2.5S which calls for just a ILSAC GF-5/SAE 0W-20. The latter available anywhere, the 508.00 not so much.
Factoring out the warranty stuff, and the dye, is there really that much difference b/t VW 508.00 and say for example Castrol Edge 0w-20 Dexos2 (ILSAC GF-6/API SP)
The Mazda Skyactiv engine is a well engineered engine and so is the Tsi 1.4. Is there really something different about the specs of these two oils that would make them so different that either one could not be safety used in either engine?
Not saying I'm going to use a non 508 in the VW, but I'm curious and wondering if the oil gurus can identify the specific specifications that would make these oils non compatible, or is it more just a VW marketing thing.
