Oil filter Mann or Wix

I would recommend a MANN oil filter. They build the ones VW sells you over the counter.

I believe over time, the deposits will be less. The bottom of the oil pan is the lowest point of the engine. The second point is the drain plug. Between these two points the oil/residue/sludge/etc never gets removed. As many oil pans that I've seen removed, there is always a fine layer of 'stuff'.

Pracuję przy niemieckich samochodach od ponad 40 lat. Wiem, co działa, a co nie. Czy chciałbyś podzielić się swoją opinią na temat tego, dlaczego większość [jeśli nie wszystkie] niemieckich firm samochodowych polega na tak zwanych „gorszych” produktach? Niestety, opinie takie jak Twoja opierają się na opiniach, a nie na faktach. Gdyby były tak gorsze, jak mówisz, typowy niemiecki silnik nie przetrwałby okresu gwarancyjnego.

installed a Mann filter. torqued the filter housing and noted the paint dot on the filter was tightened to the same location as before i started.

So my car has 86k on the clock and its an Edition 30 GLI. Great car by the way. I service it every 5k with Mobil 1 0W-40 Euro Formula (502.00 spec) with a MANN filter.

The 30 is the way to go. It's better in most every way and is not that much more. They use a better filter media and seals for a longer service life.

Mann & Mahle filters aren't all that expensive and since needing them won't be a surprise type event; buying them can be scheduled prior to need.

Their WIX XP line is about as good as you can get. Virtually the same as the FRAM Ultras. For normal WIX filters, I consider them to be average. They are what you should get at minimum, anything below is not worth buying. A "gold standard" in fitlers, if you will.

I typically use Mobil 1, Valvoline, or Pennzoil fully synthetic 5W-30; whatever is on sale. I use a full synthetic and change it every 5000 miles.

Use a good quality oil filter too (not Fram). I typically use Napa Gold, Wix, Mahle, or Mann

I typically use a Volvo/Mann filter, with 4K intervals.
