Oil filter AMSOIL or AC DELCO

AC Delco OEM filter is all I have used on my GM trucks in a long time.

I also use an ACDelco filter (blasphemy, I know).

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.

I do this every time. I buy my amsoil and filter and the dealer only charges me labor

Absolutely not. Example, I was an equipment manager at a Petroleum tank company. On our generator I tried to use several different manufacturers and the all blew the seals out because of filter material and pressure valves they used. I ended up buying OEM filters and never had a problem after that.

I'm running the amsoil remote filter, it will help with your oil quality.

I installed an AMSoil satellite oil filter. I change it out every 15k and change my oil and primary oil filter at 30k.

I've tried a number of different filters from OEM, Purolator, Amsoil, and Prova. I will say this. When I used the Amsoil filter and did an oil change, the oil came out looking like it went in. So no, not all filter are created equal. I haven't done an oil change with the Prova yet. Not driving as much with WFH.

AC Delco oil filters are now all made in China (but they won't confirm nor deny this), so they have a single package for all markets they serve.

the local gm dealer here uses the cheap delco filters and they always make my oil pressure drop 10psi
