Oil filter Mann or Bosch

I used the Mann 950/4 on my 1.8t and sent my oil out for analysis to Blackstone labs. They reported that the filtration level for that filter was superior.

I always use Mann as well with no issues.

My g/f and I use Mann filters in both our GTIs and never had any issues.

I had this very same problem with my golf. Replaced both oil pressure sensors....nothing. Did an oil change....nothing. Replaced the instrument cluster....nothing. I was about to pull the pan off the motor to check for clogging on the screen or if the pump was faulty when I thought about an engine flush. I did just that, new 10w40 oil and mann filter and problem solved.

I ordered and received a bunch of maintenance items for the Van. But I plan to cover: Fuel lines (finally) Trans Filter/Flush Rear Diff Gasket and fluid Headlight Relay Kit Dual Washer nozzles Upper Ball Joints Lower Ball Joint Repack the front bearings SST Brake lines 4 corners 15W-50 Mobile 1Oil and new Mahl/Mann filter With the above it should be good for another year of backup use.

I had this issue in an old 2.0l cabrio with 165k miles on it. I eventually had to ensure I used a mann filter and 10w40 oil at all times. Never had a problem again. The better filter flows better and the heavier oil creates more pressure at the higher temps.

This is the reason I love Mercedes-Benz. The Mann filters use a fleece media rather than paper, and I have customers that routinely abuse their oil change intervals (20k miles) and they still held up. Paper filters don't hold up or filter very well much past 5 thousand miles.

If you are going to go with extended oil changes 10-20k miles you must use a high quality filter and if not a Group 3 Polyalphaolefin (PAO) oil, an actual full synthetic oil would be best. Mobil 1 and Castrol Syntec are not true synthetic they are (PAO) Group 3. Red-Line, Amsoil, and Royal Purple are the common true synthetics. If you paid less than $15-$20 a quart for oil it's not a true synthetic.

Your filter has to be high quality. Even then I would advise you change the filter and top off your oil at 8k-10k miles.

Oil filters that are able to go for extended runs are Wix, Napa Gold, and Bosch. Those are the 3 brands I trust for long term use. My truck with over 170k miles drives like it did over 13 years ago when I got it new.

I would rather run a Mann oil filter than an oem/VW filter. Same thing for the air filter.

One lesson I learned when buying oil filters for the VR6 is to NOT buy a Bosch filter. Why? They are about $10 more, and when you pull it out of that pretty little Bosch box and look at the filter, it's a Hengst.
