Oil filter Mahle or OEM FORD

My XJ channels its ww2 roots with Ford diesel oil and an FL-1A filter.

I recently installed this canister in my 24v VR6: Better anti-drain back valve in it.

I'm currently running a Mahle OC75 filter, its easier to get from Amazon, and it is only slightly longer. I go back and forth between 15W50 in the winter and 20W50 in the warmer months. The 15W is synthetic and 20W isn't.

I used to get cheap Mahle oil filters for my K100 on Amazon for $15 or so

I use Mahle filters in both my VR6 and 2.5 from first oil change. No issues.

Mahle. Best pleat design I’ve seen and according to Volvo, their primary reason they selected Mahle over MANN or Hengst.

Engine oil: I use 10w40 in my rebuilt ABA/2H. No issues. I prefer Mahle filters.

I have several VW/Audi cars and I use Mahle oil filters most of the time. I've heard some horror stories about other aftermarket filters causing some problems, particularly on the water cooled Vanagons (I have one). Mahle and Mann seem like the best option.

when I did the first oil change on my car I removed an aftermarket Filter. The OEM filter was about 1/3 larger, and weighed the same as the aftermarket filter full of oil. Just makes me wonder how much more there is inside the OEM filter.

After an oil change, the car shot most of the oil out from the filter. I installed a brand new Mahle filter, tightening it snug. After a short drive, it again shot all the oil out of the filter, with the gasket forced to the outside.
