Currently using Mobil 1 5W20 in my 99 Vulcan, as my car has been back specced in 2003 from 5w30. Currently using a M1 filter as well. Is it worth putting more M1 in my engine with a Purolator BOSS filter? I beat the [censored] out of this car. Or would it be just fine switching back to Motorcraft 5w20 Syn blend with a MC FL-400s filter?
Thanks friends!!!
