I would not hype any brand though you blatantly hyped Mobil 1. For me the brand is not important. The standard met by the oil is. For most of my vehicles I need API CH4 and mb 228.3 as a minimum combined with API SL while for other more demanding applications I need international ACEA A3 and B3 [which most Mobil1 does NOT meet] or Mercedes 229.3 or BMWLL01 but prefer to use oils meeting mb228.5 ultra high performance. Hope that makes sense and please note that Amsoil does NOT figure and I do not hype a brand, any brand.
