Engine oil OEM Mazda or OEM FORD

I use Mazdas 5w-30 Ultra DPF. Mazda once said that this was the oil that they're using, so I guess what's used by mazda can't be too bad for the rex

My wife's truck recommends 5w-20. Burns it like a mfer though. I run 10w-40 in it and have for several years. Still going strong. 01 f150. Do with that what you will.

As the owner of a 1995 Ford F-250 Powerstroke, the saying goes, "if it leaks oil, it has oil". -Ford 3:16

The 2.3 liter engine on a ford ranger takes 6.2 quarts as opposed to my corolla that took less than a gallon for the 1.8 liter engine.

My Ford Freestyle with a 3.0L takes 6 quarts, while my Pontiac Grand Prix with a supercharged 3.8L takes 4.3 quarts. Go figure. I was shocked when I saw how much oil the Ford takes.

my 2011 ford fusion oil cap has 5w-20 but when i put that oil, engine noise become loud. Only 10w-30 noise is lower and engine smooth.

Could be weather related. I'm in Canada and we have weather from -35C to +35C, so Mazda recommends oil changes every 8000km instead of 12,000km.

I use original Mazda oil and Nipparts for the filters. I live in Europe and I buy these for 80€ / 85$.

Mazda’s OEM 5w30 is a little too thin for my blood considering the engine temps when driving hard, fine if you’re going to never redline the car

For the record, this is NOT the exact replacement to Mazda 0W-20 GF-5 with Moly - Synthetic Engine Oil.

While this has high molybdenum, it's still a different formula from Mazda's own proprietary blend.
