I am just curious about it. I am nearly at 10K on this OC and I have been toying with the idea of running 15K on this filter (I will be UOA'ing the oil to see if it can go out to 15K as well), but I curious if anyone has ran a FL-820s that long.

TIA for your experiences and thoughts.

I don't think I would take that kind of risk with a $4 filter. Better to just change it at the halfway point or use a filter intended for extended drain intervals.

Second. Even if you were to swap out for a second MC 820 you would still be ahead of the price point for many extended OCI filters.

Oh no doubt; I paid $2.30 each for the last group of 15 that I bought. I probably will change it at 10K, I was just curious.

Just changed the oil today in my wife's 2005 4.6 Explorer. It has 9,000 miles with Valvoline SynPower 5W-30 SM, with a Motorcraft FL820S oil filter. As soon as I can I'll cut the filter open. Any suggestions on what's the best way to do it with a Dremel or RotoZip is appreciated, ie the preferred cutting type blade.

My neighbor changes his oil once a year and sometimes longer he uses whatever the dealer puts in and his 4.6 runs like new

Agree with the other inputs. Next time if your oil can go 15k, then just change the filter at 7.5K and top off. Or start using an extended OCI filter like the Ultra.

I am sure that it will go 10K; I have already ran one that long and dissected it (you can search for the photos). I use a filter cutter, but a hacksaw will suffice in a pinch. cheers

The big advantage to a motorcraft filter is the thread end bypass valve. Its weakness is using a paper media rather than synthetic. Paper will decay with both time and or mileage. I would roll a new filter every six months or 6000 miles.

15K might be pushing it a little. If your UOA says you can go 15K on the oil, I like ZeeOSix's suggestion to change at 7.5K and top off. BTW, $2.30/each for those filters is a major score! Even it you use two per OCI, that's only $4.60/OCI vs $7-9/OCI for a Fram Ultra.

I've been meaning to ask you, is your current oil selection a secret until the UOA is posted? grin Looking forward to it.

I guess I will not push the envelope; I have a few hundred miles to hit 10K and I will change the filter then. As you said, I could use 2 for each OCI and still be ahead of the game. AAP and those codes have been veddy veddy good to me; $2.30 each out the door was a steal.

PS...the name/type of the oil is being withheld to protect the innocent (me) and the foolish (my friend), who, by the way, has found that crow goes down much better with a quart of your favorite motor oil. whistle grin

What kind of special filters was Honda using with 10k mile OCI and only changing the filter every other time? The answer is nothing special. Any MC filter should do 20k miles no sweat in a non-sludged motor. Changing a filter at some magical number like 10,000 miles is laughable to me. Many people never change them at all, the filters don't blow up nor do the engines. A friend runs Purolator Classics in his Chrysler mini van for 18,000 miles (or longer) with no issues. He doesn't lose any sleep thinking he's pushing the envelope either.

After 10K, the ADBV looked like this:



The whole dissection is here.

My concern then and now is the ADBV failing due to "wear". Would running it 15K or 20K cause a failure? No way to know unless it is attempted...and I had hoped someone had already been adventuresome wink

My 1994 350+k miles LS40 OCI: 7-8k/6mo with dino, 14-16k/12mo with syn. FCI is once a year, reuse oil filter with dino. The most expensive oil filter I use in that car is P1, other filters are OCOD, Motocraft FL400S and other various low cost filters($2-3).

I think in a clean engine there isn't much to filter, even the OCOD can hold 6-7 grams of debris. If an engine generates more than 6-7 grams of metals then it's dying, no matter how good a filter you use it will die soon. That LS400 engine is still running almost as smoothly as new, the other car parts is different story.

The filter is mounted horizontal on that engine, after 1 year of use up to 15-16k miles the filter still had much oil inside after laying upside down for several days, that means the ADBV was working okay.

Summary, you can use Motocraft oil filter for a full 15-16k miles OCI without problem !
