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.
YES! My 2012 Skyactiv is at 233K miles, and has always had the Mazda Moly 0W-20 (with the exception where I was able to get the Idemitsu version, which is the same stuff, but without Mazda's markup. Sucks that it isn't available anymore. ) and I'm not about to chance running a different oil.
Always run a Mazda filter too. The quality seems better than most.
I use OEM Mazda filter. Synthetic oil, Kirkland brand or Castrol since i think thats who makes the Mazda oil.
Penzoil ultra platinum with a Motorcraft oil filter.
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.
Motorcraft oil filters are also known for being of great quality.
Purolator was the producer of our filters last time I checked. Motorcraft filters are surprisingly good considering how cheap they are. The bypass setup, filter media, housing and overall quality are higher than what you’d get at a fast lube place.
Motorcraft filters are made by Purolator. It's been my experience that Motorcraft filters work perfectly fine. I used Motorcraft oil as well until I switched to full synthetic.
The Miata is pretty easy to work on. But ironically, one of the simplest jobs is a major PITA, changing the oil filter The thing is buried underneath the intake manifold.
