Oil filter Motorcraft or Castrol

For oil filter, I run the same one on my 302 and 390: Motorcraft FL-1A. I believe it is (or was, at least) made by Purolator and is my go-to for my old Ford V8s.

Buy an OEM filter and the top spec Castrol/your chosen top tier brand.

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.

Buy Castrol Edge and the long-life filter from Walmart for best engine protection.

I did Castrol Edge Euro Car 5W-40 with a Hengst oil filter, but if you want to spend a little extra most people recommend LiquidMoly

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.

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.

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 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.

I've seen those leaking at the crimp now multiple times.
