Oil filter AMSOIL or OEM Subaru

Only ever use Subaru OEM oil filter on mine and penzoil platinum full synthetic

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 have 234k miles on my 2016 Outback and I usually use Napa or O’Reilly house brand oil and either a Subaru or WIX filter.

Also get a good Putolator or Subaru brand oil filter that is rated for the higher Subaru oil pressure so that it is filtering more often and not blowing open the internal filter bypass because Clean oil will make the engine last longer.

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

I have used the Amsoil Premium diesel oil and filters for the last decade, changing them once a year, and my truck is doing just fine.

I use amsoil oil and amsoil filter

I have experience with the long drain intervals from Amsoil. I have 2 dodge vehicles with 3.6L engines both at around 130,000 km and I use the signature series 5w20 with Amsoil filter and I go about 18,000 km before I change the oil.

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.
