Use a good oil filter too (Motorcraft 820S will do just fine, stay away from Fram).

What exactly happens when you mix synthetic with regular oil, all in one shot (like half synthetic and then mix half regular after an oil change)? I didn't do it myself, I've been using synthetic forever, i'm just curious as to what it does to the motor.djtech said:You can even mix synth & non-synth. Not sure why you'd want to but you can.

COBRA90GT said:Fram oil filters did not hold up very well, at least that's what an oil filter test has stated (it is out there on the web, someone did a very thorough test of many of the available oil filters on the market - you could try Googling for it or running a search in here or on Corral.net's msg board for the exact study results).

Roush21 said:Hmmm Ive always heard Fram was good. I just started running Royal purple synthetic and picked up a Fram filter to go with it. Next time I might get a Motorcraft. I was going to get the K & N but it was $12.95 that's kind of expensive compared to $3.29 for the Fram and $3.99 for the motorcraft and its only going to be used for 3,000 miles anyway so....Thanks for the info/advice COBRA90GT
