Bought a used M35 two months ago. Happy with performance so far. Got 24.6 MPG on 70 mile freeway trip from grandma's house with cruise set at 67 mph. Does anybody do better and have suggestions for improvement? thanks
I have a 2010 M35x. The dealership has always used regular oil, but they have closed where I live. Can and should I switch to synthetic oil? Car has about 30000 miles on it, and we put less than 7000 miles a year on it.
