Larger V-10 oil filter

[John Wayne]

The Dec. copy of MotorHome in the power train section has the oil filter numbers for a larger capacity and higher flow rate oil filter. That will fit our V-10. The numbers are.. Motorcraft FL299,Wix 51773, NAPA 1773, Fleetguard LF697, Purolator L40017, Fram PH977A

That's great, thanks for the info! I always wondered why the filter was so small.... Why wouldn't Ford just use their FL299 to begin with?

Haven't heard "one size fits all". I use the same Ford filter on my 5.4 V-8.

The FL820S is a metric thread filter, M22x1.5.

The info I'm finding on an FL299 is that it is a 3/4x16 thread. Doesn't quite add up.

Would be close though, M1.5 pitch is about 17 threads per inch, and 19mm is close to 3/4".

I'll stick with the FL820S for now.

(And keep Googling....)

How about this Ford Racing FL820, 50% more filtering capacity

How much more oil do you put in on the oil change?

[dusty567]

Got to add more oil for sure. You can always use your old filter and the new one to measure the difference. Thats what I would do.

Always thought the FL-820S was a pretty small filter for the v10, however in 69k miles using Mobil 1 synthetic, no problems. Will consider the larger filter for next oil change. It appears it may take an additional 1/2 to 3/4 quart of oil.

With <5k miles a year, I wouldn't think the filter size would matter that much. You'll be changing oil on a calendar basis rather than mileage.

I went out and bought 2 NAPA 1773's for my 2006 V-10 per the comments by Ken Freund in Motorhome Magazine..

The 1773 does not fit.....The port opening is smaller than the stock one by about an 1/8" or so.....Side by side comparison of the 820S and the 1773 and you can see they are diff sized openings.....Don't know about the others listed ...

Here is some info from another site on the larger filters.

"I did some checking today on those oil filter's for the V10 engine. Went to my local NAPA auto part's store & the manager, desk clerk & myself checked those number's & none of them will fit.
At the NAPA store, they have this book that list evey filter one would need for any car or truck, the part number's & all the different measurement's for each filter.

The normal Motorcraft filter, FL-820S for the 98 & up Ford 6.8L V10, has a 22mm screw in port hole X 1.50 pitch metric bolt thread.
The flat o ring sealing gasket on the FL-820S, measure's 62.54mm dia

All those filter part number's listed in the above post, have a 3/4" american pipe thread screw in port, which is same as the regular FL-1A oil filter that will fit most Ford engines.
Motorcraft, #FL299
Wix, #51773
NAPA, #1773
Purolator, # L40017
Fram, #PH977A
All have the 3/4" screw in pipe thread port, but have the 62.54mm sealing o ring gasket just like the FL-820S.

We went through the NAPA book & found some numbers that have the same measurments as the FL-820S & are 2 qt filters.
Motorcraft, #EFL-252
NAPA Gold, #1087
Fram, #PH-2975
I ordered the NAPA Gold #1087 filter & should have it tomorrow to check even closer.

Something I did find, for those of you that use the normal FL-1A oil filter & have room on your pickup to use a 2 qt capacity longer filter, the NAPA #1773 or the Wix #51773 has the same 3/4" port as the FL-1A.

I could stand corrected on this, but the manager, clerk & myself all checked the book behind each other & this is what we found.

I dont know about the filter bypass settings & I'll see about checking on those tomorrow, to make sure that they are the same."

There is no reason to change the filter FORD selected for these engines. I don't understand the second guessing of an engineered product. Your engine will not get any benefit from this experimentation. I change my oil on or about 3000 miles. Sometimes it is inconvenient in out of the way places. I still do it. Just how much crud does Motorhome magazine think is in your oil that more filtering material is needed? I think the Motorhome magazine people should not be making recommendations. They must be desperate for things to write about. I'm glad folks took the time to post their findings.

It does give you just a tad bit more cooling, because of more oil but more importantly the little bit extra the filter protrudes from the engine in the air flowing over your engine while driving.

It's like having a small engine oil cooler every little bit helps in the summer pulling that long hill in hot weather.
