I purchased some Mobil 1 SuperSyn 10w30 labeled "For Higher Mileage Cars". I also have some 5w30 labeled "For Newer Vehicles". When I bought the 10w30, I assumed the 10w30 was labeled as such because most new vehicles recommend 5w30. I also suspected it was just a marketing thing.
Is it safe to run this 10w30 in a new vehicle? Does Mobil make a 10w30 SuperSyn for "Newer Vehicles"?
I'm doing a VOA on the 10w30 to see what I have, but it won't tell me what the ester makeup is. So I guess I'm wondering if this is just a marketing label, or do they really have a high mileage formula in the SuperSyn? It's in the 5qt bottle I bought at Walmart.
