Oil filter AC DELCO or OEM Volkswagen

Get the afm tuned out. And use ONLY full synthetic oil and a ac Delco filter. Mine has 232,000 and has been super reliable and still runs like new

7 Qts. Mobil-1 5W-30 Standard Full Synthetic, 500 mL bottle Rislone Engine Treatment, ACDelco PF61E. That's what I've used for all of my oil changes I've done on my 2008 and I've had absolutely no problems.

OEM AC Delco

Been using just regular t4 Rotella and AC Delco filters on all of my diesels since 2011. No complaints

VW Genuine filters used on all oil changes too.

Tbf the b6 passat will probably rust away just by existing before the engine gives up. That being said, 1.4tsi engine is not great not terrible. Many problems with them are caused by lack of maintenance and by cheap oil filters.

I'd just recommend getting a VW oil filter. Some of the aftermarkets are really cheap and can collapse in on themselves.

B5 Passat (and Audi A4, same gen), 1.8T.

Filter - a big-ass 1.5 liter spin-on - mounted at an angle, directly above the front subframe.

Remove from top, after relocating the coolant tank.

Strategically use absorbent mat (floor diaper) to contain the inevitable spill.

Ac delco/delphi quality has been getting really bad. There’s a cheaper line of products that are all Chinese and then a higher level. I stopped using their oil filters when the threads were completely off for my 3800.

I changed the oil with an AC Delco PF66 filter. Turned on the car and it instantly started spewing oil. Immediately turned it off. Oil sprayed through the cracks in front grill/bumper panel on passenger side.
