Oil filter Mann or STP

Synthetic oil has become much more costly in the past few years. I was paying about $45 for 10 quarts of synthetic and a Mann filter in 2019. It's now about $76 for the same.

Bought 2 x 20 litre drum of Havoline® ProDS Fully Synthetic LE SAE 5W-40 when the Caltex name left Australia & Ampol sold off all the left over Caltex oil cheap at Repco. $42 for 20 litres!!!!

I also use MANN W719/30. That filter is designed to go a longer interval and for synthetic oils.

New Mann oil filter

Mine was from May 2001, changed it out last year and it for sure made a difference.

wenn möglich Ölwechsel bei Mac Oil durchführen lassen, kostet je nach benötigtem Shell MotorÖl zwischen 50 und 80€ inkl. mann Ölfilter und zurücksetzen des Service, plus eintrag ins Scheckheft. dauert ca. 15 min reine Arbeitszeit und kann im Auto sitzen bleiben. unschlagbares Konzept.

As far as filters: Mann. If it's isn't Mann I won't put it in my car.

A vehicle engineer friend of mine recommended Motul X-Cess 8100 5w40 for my C43 (W205, M276) and a Mann HU 7025 Z filter.

I use liqui molly and Mann filter every 6k miles on mine.

To me it looks like you have a cheap shitty non oe/oem filter installed. I'd change the filter to a good brand, (mann/mahle/oem bmw) and then clean the area with brake clean then let vehicle run and recheck. If it's leaking as bad as it looks like it is it will be easy to verify that you fixed it
