Oil filter AMSOIL or Motorcraft

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 use Motorcaft synthetic oil and filter. It's what the manufacturer recommends. There are probably 50 other oils out there that are just fine for regular driving and the occasional burnout. I just tend to stick with what the people who designed the engine would recommend over what someone on the internet does, unless there is a clear reason not to. And if you disagree, you do you.

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

My feeling is pick any reputable fully synthetic oil and stick to it. Make sure to change more sooner than later.

But my feeling is the filter makes all the difference some of those OE spec aftermarket are not as much OE spec. The Motorcraft filter has specific bypass valves that allow optimal oil pressure when you need it. This is crucial for a healthy 5.0 coyote motor.

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

For 7 years i’ve religiously used motorcraft 5w-30 and motorcraft oil filters in my ‘97 crown vic lx and it’s been great

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 maintain 4 6.7s, in f350 and f450. Motorcraft filters and full synthetic 5w40 are my choice. I send Blackstone oil samples periodically and change them at 8k. So far, Blackstone keeps telling me I can let the oil go longer.

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.
