Re: Mobil 1 Oil
I must say you DO NOT need to change your oil that often. The reason that they suggest 3-5K is to make sure there is no leaks.
I know I will get backlash but European's change their oil about every 15,000 miles. The cost to change the oil is very very high there ( like $120 ). They are running diesels too were running temps are usually hugher.
THis being said I change mine between 6-7,500
