Oil filter LIQUI MOLY or AMSOIL

I just go to the amsoil website and get the oil that they suggest, I've taken cars well over 200k with that advice. Don't overthink it. If you don't want to use amsoil for the oil, at least see if they have a low micron oil filter.

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.

Liquimoly is more expensive, sure, but that’s what I buy. Comes in a nice little kit with a filter and I know I don’t have anything to worry about.

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 use amsoil, pricy but the filter is what's really worth it and before I changed my valve seals I burnt quite a bit less, it went from a quart every 800-1k miles to a quarter quart in that same time frame.

I change my oil filter every oil change n my advanced synthetic oil liqui moly last 9K

I used Liquimoly 5w-30 when I was NA, and still use liquimoly 5w-50 since boost. A little pricey ($120) for 10qts but worth it. Oil filter, just a ford performance filter. Pretty much any auto store will have them or a comparable brand in stock. When I was NA I’d do oil changes every 3k miles or sooner depending on how hard I drove it. Now with boost the max I go is 2k miles. Normally 1k-1.5k since I drive it hard and run e85.

I have religiously changed the oil and oil filter every 5k miles with Liqui Moly TopTec 4200 (with VW spec).

I was using Kirkland synthetic before for topping off and other American oils for oil changes I’m sure, but then I went to a euro auto shop and they switched out for a German filter and oil, LIQUI MOLY, and I got a significant increase in mileage.

I recently switched to Amsoil using a Mann filter. It runs great.
