All filters are bad on this forum if you listen to enough post Run em and let us know if you blow a motor Then we’ll have something to talk about

I don't think I'd want to wait to conclude a filter is sketchy after it caused damage. That's like walking in a mine field to find mines, lol.

Well, the data doesn’t lie. Why use a filter with poor capabilities? Just doesn’t make sense, IMO

Might as well use a .99 rock auto special then with that line of thinking . Good chance it would be better than a Motorcraft anyway.

Based on some of the reports of the black glue coming off and going into the engine, I wouldn't be taking any chances. All engines with VVT have screens to filter such things like that, and something happening like the glue coming off can cause VVT issues. In fact, Motorcraft talks about it in this video. Video starts where talking about debris, which could be glue from the filter.

I just bought some of those as well. Only bought 7 though. Used one today, cut one open for the forum tonight.

Bought 7 of them. Used one today, cut one open tonight. Not the best filter I've ever seen, but I don't see it being a problem for 5k changes on the F150 Hybrid.

I’m not taking up this argument.
All I’m saying is is it’s not the smartest decision to knowingly use a poor quality filter. Just makes absolutely no **** sense.

Defective Fram Ultra destroyed this Mazda engine. A piece of the ADBV broke off and got sucked into the engine. Fram covered the repairs.

GM also issued a TSB for oil filters damaging engines.

Think in that case it was the whole ADBV. In the big thread about that case, the theory was the filter was a "rattler", and most likely during a cold winter start-up the high dP pushed the ADBV out of the filter and into the engine. That's why it's a good idea to shake all filters that use a stamped leaf spring to ensure the guts aren't loose and rattling around. If it does, the ADBV is not pinched tight against the base plate.

I cut one of the 12 pack open. Nothing crazy. A little bit of extra glue but no mare than I’ve seen on other filters. I’m running them!

Will that sloppy black glue on the end caps come off with a fingernail? That's the black glue that's known to shed in use.

I tried to peel it, and tear the media. Media took quite a bit of force before it gave way. I didn't notice the glue coming off at all.
