Oil filter Bosch or Mobil

I run M1 5w40 with an M1 filter.

I’ve also used Mobil oil filters because they’re easily accessible and manufactured by Mann.

I always recommend using a synthetic oil and a Mobil1 Extended Performance filter every 5k miles.

I run this same oil and Mobil 1 filter in my 2009 Yukon XL with a 6.2 L V8 with 148k miles. I usually change my oil every 3k - 5k miles despite what the marketing says.

NAPA Gold filter (Wix) and Mobil 1. Great results on last two Legacys.

Honestly I just use whatever BMW certified oil I can find at a good price. Used Motul this time, had Castrol before that. Bosch oil filter.

Thanks for the quick reply I'm run ing 5w40 mobil 1 European spec oil ans mobil one extended performance filter I change it every 5k

I usually buy my own oil and filter the 20k mileage mobile one brand and have a shop do it for 20 but I’m 500 miles away from home. I change it at 10k miles just to be sure. I’m away from home to often to change every 3-5k miles so this 20k mileage stuff is great and haven’t had a single issue!

I have a 2001 Passat 1.8T, on which the oil and filter have been changed every 6 months or 3K mi, whichever came first. The dealer performed the first 4 oil changes, to the 2-year point, then I took over, always with a Bosch or Napa Gold (Wix) filter. Having received the engine sludge notice, I switched from name-brand dinosaur oil to Mobil 1 at my most recent oil change (last month, 23K miles). Although I receive no adverse temperature or indications at the instrument panel, the valve cover SEEMS perhaps to be running a bit hotter than before. What really concerns me is that, when the engine is warmed up, if I stop and idle it for 30 seconds or so, the engine starts making what to my semi-practiced (but new to VWs!) ear sounds perhaps like valve, lash adjuster, or camshaft bearing clatter. The sound emanates from the rear/cylinder 3-4 area, away from belt-driven accessories, etc. Does this sound like an early symptom of sludge, perhaps associated with insufficient oil pressure at idle? Given my history of frequent oil changes and otherwise by-the-book or better maintenance, I would not have expected to be a sludge victim at 23K miles. I suppose I could have just installed a defective brand-new Bosch filter, or I suppose the synthetic oil could have loosened some sludge from my dinosaur days, but these seem like real stretches for an explanation. Any suggestions regarding diagnostics?

Bosch filters are almost as bad a FRAM now.
