I’m wrapping up an oil change and thought to share the procedure. I’m not sure if it’s on here or not. All you need is a lift, a good 76mm 14 flute oil filter wrench, and some patience!

I’ve got the procedure down to about an hour’s time and a little under $250 for the parts.

A few pointers to add:

The filter can be difficult to get off. Until I can find a better wrench, I’ve need channel locks to get it broken loose.

The procedure doesn’t require it, but if you hold the accelerator pedal to the floor when cranking you can build oil pressure prior to starting the engine.

O’reilly auto has been my best local source for Motorcraft 5w50 ($10.49/qt)

The filter is a dealer only item.

A good quality filter wrench is needed. I think I have a Lisle. I tried a generic from a parts store, did not work at all. I got mad at that one, and used our hydraulic press to turn it into a pancake, and threw it away.

Agreed, I have a few different ones and they all slip. I use a big pair of channel locks to break the filter loose, then use the gear filter socket I have. Going on isn’t a problem, I’m able to achieve 3/4-1 turn past contact with the filter wrench I have.
