It is garaged otherwise !
Several books say change engine oil at 16000 miles interval. Some say once a year!
I am using Mobil 1....
What do you think,please? Thanks in advance

do they sell Mobile 1 5w-40 where you live? because they don't here and I have to use Castrol. just wondering what you are using. I think you could get a little more mileage than that out of fully syn. but if you have the money, can't hurt. 9 quarts is like $70 here.
