Oil filter Bosch or AMSOIL

I do a lot of miles in my diesel so I buy in bulk from rock auto and the shipping barely goes up

My last order I made sure to get all of the filters from the same warehouse while still getting good brands like Wix and Bosch

I always buy Bosch filters for both our VW's

I use Amsoil Signature Series & OEM filter.

Just change it every 6,000km and you’ll be good. Use synthetic, but brand isn’t as important as proper drain intervals.

Always used Bosch Premium once warranty was up. Anyway, tech said Bosch is his first choice for a good substitute and probably even better than Honda. I tend to agree.

The Bosch oil filter and Mobil 1 5w20 combo is what I've been using for years for my 2010 TSX

Kaufe ausschließlich Markenfilter, BOSCH oder Mann. Was anderes kommt mir nicht ins Auto. Und ein kurzer Ölwechsel-Intervall (10-15k) ist auch nicht schlecht für die Gesundheit des Autos. Am Öl und Ölfilter sollte man nie sparen, die potentiellen Folgekosten sind einfach zu krass.

I was skeptical, but I started using it and their best filter in my '98 Durango 5.9 (gas). I ran it for the full 25 K(+) and sent an oil sample out to a 3rd party "Analysts, Inc." for a full analysis - including spectrographic. Basically, their recommendation was that the oil showed minimal contamination, acceptable viscosity, and was still OK for continued use and to re-sample at next interval.

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?

Just had an amsoil filter fail at the gasket. The inner diameter was too small causing a crease in the gasket that leaked after 4 months use. Nearly ran me dry.
