oversized oil filter for PCM 351?

Im not sure that Ive seen a bigger oil filter than the Motorcraft FL1A or Wix 51515. If I fit it on my truck, Id use it!

Id stick with the proven filters.

Tom,
I agree with Tim. Stick with the proven filters (except a Fram!!)

Unless you are going 4 or 5 times beyond the recommended oil change interval of 50 hours, the standard filter has plenty of capacity. You will NOT get better filtration with a larger filter - just more capacity.

How often are you doing a oil/filter change?

Who told you a bigger filter does a better job? Advertising? FYI, a half plugged filter cleans down to a smaller micron size!

Yeah, I don't think there really is an easily available oversized filter for these motors. Even if there is, it's pointless unless you run synthetic, and even then, putting more than 50 hours on in a season is tough for most folks up north with our short season.

When I had my 4.0 I6 jeep, I used the same filters that I use on my nautique, and those were the same as on my 2 different 5.0 mustangs.

The original spec'ed filter for the 4.0 jeep was simply a shorter version of the Fl1A sized filter. For me now, the boat is the only vehicle that uses that size filter. 4 different vehicles, 4 different filters. ugh...

My parent's 4.7 v8 grand cherokee can fit the FL1a type filter too. At one point, we had like 7 vehicles from 2 different manufacturers , not including the 351w boat as a different manufacturer, running the same filter. That made buying filter easier than it does now.

No Pete, I make 4 different trips for my filters.



In the past, writing it down wasn't necessary, but now it is:)

Speaking of filters, has anyone else run into these filters leaving their gasket behind? No big deal because it's so easy to see but just weird.

I've worked in entry level auto repair jobs and have done hundreds of oil changes. I remember being warned about "double gasketing" but it rarely, if ever, actually happened. I want to say less than 1% of the time.

I changed my boat's oil once when I got it in the spring, once mid season, and once before storage. The old filter left it's gasket on the engine all three times! I forget the brand that came with the boat, but of the second two, one was a Wix and one was a PCM, so at least 2 different brands did it.

I've only ever heard of one stick on the motor once. That was at my friends oil change shop. And yes, it leaked BADLY when double gasketed. It never left the parking lot of the shop. Granted, I didn't see it happen, but I saw the oil stain just past the building.

That FL-299 was the filter used on the old Ford F-600 thru F-800 gas motored trucks. It had a lot of extra capacity for the severe duty use expected on those vehicles. You can always go to the Ford Racing FL-1A which is their ultimate filter. It's really built for the high performance engine in mind. The heavy gauge of the filter makes it weigh about twice as much as a standard one. If your engine is stock you can't go wrong with the Motorcraft FL-1A that the engines came with from Ford.

PAPA stole my thunder,i used to run the fl-299 on my trucks to get extra capacity.they still make them,verified this morning.
