Why I will never use non-motorcraft filters again

[trippd6]

I recently bought a 2003 F250 with the 6.0L. I decided soon after buying it to change the fuel filters, oil, and oil filter. I went to autozone and bought motorcraft oil and non-motorcraft filters.

After seeing the Ford powerpoint on why to never use non motorcraft filters in a 6.0L, I decided to order the motorcraft filters and swap them in after about 1000 miles on the autozone filters.

Below is a picture of the autozone filter I pulled out after only 1000 miles. It looks to me like it collapsed and was probably restricting the fuel flow. I had a 3 MPG drop in fuel economy on my last tank, and I drive a fairly consistent number of highway vs city miles (I drive 50 miles to work each way, mostly highway).

Its seems my acceleration is also better after installing the motorcraft filters, but it may be in my head.

Thoughts?

I'd say she was drinkin' through a pinched straw. I'll remember your thread the next time I change mine. Thanks for sharing what happened.

Looking at it again, it looks like the top and bottom of the filter have rotated in relation to each other. Either the autozone filter is the wrong length, or it got hung up on something while screwing on the cap.

I'll pull the motorcraft filter off at some point to make sure it didn't happen to it as well, but I would assume its fine.

Either way, I'll use motorcraft filters from now on.

Motorcraft filters FTW

some of the off brand small filters have fins in the upper middle wich will catch on the cap and cause the twist some dont just inspect before purchase

When mine did that and was running napa filters I lost my fuel pump

What did that fuel pump cost ya, if you don't mind me asking.
