I've been seeing an ad for mobil high endurance oil 5000, 7500, 15000 miles between changes. I'm just trying to get an opinion wether or not I should use this oil. I tried to look for it to see if it was synthetic or not( been using Mobil 1 ). I think that if it is a synthetic oil it should be ok. I don't really drive my car too hard and ony race every now and then.
I plan on getting the 7500 mile oil. Any opinions on this?
