Heres my question.
1) in a week or do I will get an oil change. Go with motor craft 5w 50 or royal purple 5w30?
2) I was to change the tranny fluid to this synchro max stuff. Has anyone used it and how good is it?
Any input helps. Thanks guys
1. 5w50 is for track pack... If you don't have track pack stick to 5w30
2. Synchromax is great stuff!! I have that in my tranny and it's far more smooth
