Owner reviews for oil filter

I noticed a huge difference in how clean the oil was midway between changes when I went to a Mann filter from a Purolator filter.

I do use Mazda filter rather than aftermarket.

Fram makes GM oil filters. At least they used to. Compare the black (factory) filter or the AC blue filter next to a Fram. Same dimples beneath the grip on the Fram. IIRC there are two companies that make most of the normal oil filters. Even the expensive Mobile 1 filters, though those just use higher micron elements is all. Wix is the other company. Not sure who makes Subaru's but I'm sure it's the same story. Been personally using them for decades, never had an issue. Wife rolled her Honda over 500K using them every 5,000 miles.

Best is sticking with OE stuff (VW, Mann, or Mahle - Mann filters can be had from many places online.) If I were to shotgun parts at this (read: not bother checking pressure with a gauge, just throw parts at it), I would do a good filter, and an actual VW pressure switch

There is that possibility, I have had a Fram filter that self disintegrate inside due to age of the filter ( I had them for a while before use).... when I finally took out the filter and shakes it, it was definitely loose. It was causing that same oil filter light intermittently.

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

Wix are a pretty high quality replacement per my experience. Wix are certainly good enough to validate that behavior is not unique to the STP filter.

I run all of my fleet either on OE VAG filters or Mahle and Mann who are the OEMs for VAG. I buy filters in bulk, depending on who has which filter at an attractive price at the moment. Right now I have a Mann HU 719/7x in the Eurovan - according to the maintenance spreadsheet I bought it for $7.72 from autohausaz.

I went to Pep Boys Auto Toys and bought a Fram PH2870A. The day after my girl called me and said that her oil light kept going off, the pressure differential across the Fram was so big that it tripped the oil pressure switches. I replaced it with a MANN and tested the pressure and it was right where it was supposed to be.

anyone know if the mahle's are still made in a decent place. no more mann filter on my car, at least not the chinese ones.
