I use the M1 Extended Performance filter along with the M1 Extended Performance oil. It costs a little more than the standard M1 oil, but it lasts me around 10,000 miles.My Pro4X has almost 7200 miles on odometer now. Thinking ahead to next service visit. Think I'm going to go with Mobile One Synthetic. But don't know which Filter I want to go with.
Would like to know what oil & Filter everyone uses?
