Oil filter AMSOIL or Castrol

I used the Castrol once, and have been buying the assembled kit from ECS ever since. At 73K miles, now, and change it every 7-8K.

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.

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

Castrol Edge 0w 20 with the Dexos1 and an STP gold filter done at 2k.

7500 miles religiously, including filter every time. Full synthetic 5-30 Castrol.

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

I buy Castrol edge and Mazda oil filter off Amazon.

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