I wanted to like it because Luber-Finer had a good reputation back then, but it's too low for a Mercedes OM642. Slightly, but there is. And the o-rings at the end don't cover enough and are too thin to make up the difference. I suspect oil is leaking. I can't prove it, but if you put one next to Mann, Mahle or OEM you can see it's just a hair. O-rings are ok.
