I am buying an 02 F150 with the 4.6l. The previous owner has been using Mobile 1 full synthetic in it since 85k miles, it currently has 134k. I have always ran Motorcraft synthetic blend in my 2011 with the 5.0 and would like to switch the 02 to Motorcraft also. Anyone see any issues going from full synthetic to a blend? Also anything in particular I need to be aware with this year truck? The owner seems to be very meticulous about his maintenance on it so I think it's in pretty good shape but any pointers on things to be aware of are appreciated.

 

No problem

 

That's what I figured but I've never claimed to be a mechanic. Figured I'd get some opinions on here.
