Oil filter AC DELCO or Hengst

My E550 gets M1 0W40 every 5k, with a new fleece Hengst filter. I don't drive it hard until I see past 80C on the water temp (I don't have an oil temp gauge- only the E63s do). Basically the same procedure I use on my S54 BMWs, and every performance car I've ever owned

I do the oil every 5k on both and use liquid moly 5w40 and a hengst filter.

I use Liqui Moly Leichtlauf and Hengst filters from FCP Euro on my 1.8T Passat. Highly recommend.

Absolutely not. Example, I was an equipment manager at a Petroleum tank company. On our generator I tried to use several different manufacturers and the all blew the seals out because of filter material and pressure valves they used. I ended up buying OEM filters and never had a problem after that.

I use liqui moly but I have my doubts about whether it actually is *the best* oil. I'm sure it's good, but any oil that meets the spec called out in your owners manual is "good". I place more weight on the filter than anything else. Hengst for me, get that Fram shit outta here.

Liqui Moly Oil change 5W-40 with Hengst Filter

Since I've owned it, I've performed all the work listed below with genuine VW parts when possible. I've also flushed the oil with Liqui-Moly engine flush, and performed a Seafoam cleaning. Afterwards, oil was changed to Liqui-Moly 5w40 Synthoil Premium and new Hengst oil filter.

Official VW filters are Hengst's with a little VW logo and part number printed on the end just note that the filters do not include the gasket for the oil-can drain plug (dunno if that's on the mkIII's, but it's on the mkIV's). Just means you can't really drain the can, just unscrew it and be quick to minimize the amount of oil that goes flying

the local gm dealer here uses the cheap delco filters and they always make my oil pressure drop 10psi

For oil filters I feel like the ACDelco filters are pretty low quality and there are many better options. Mobil and K&N oil filters are available at Walmart for $10-15, made in USA, and seem to be much better quality.
