I usually get Synthetic oil for my vehicle so that I don't have to change the oil every 3000-3500 miles. Now I go around 5500-6000 miles on Synthetic oil. However, I noticed as I went to the gas station that for Mobile Oil (synthetic) that it says you can drive your car for 1 year or 15,000 miles on it, whichever comes first.
I want to know do any of you use that? Is that accurate? Can you really drive a car for 1 year or 15,000 miles on 1 oil change where the oil is still good as if on a regular oil change of 3000 miles?
