Toss a coin both are great oils. I favor YB but would have absolutely have no problems using MC oil in my Aerostar, which I run Dino oil in. The MC filters are good, I prefer Pure One filters, but have used MC filters w/o issue.
If you can purchase the MC blend for the same price as conventional use it. I use OEM filters, nothing wrong in that choice. Until recently I used QS Greenbottle 5w20 because it was the factory fill that Hyundai uses. I'll be away in PA til Sunday night, you guys enjoy the weekend.
I would have absolutely no problem with using a Motorcraft filter and Motorcraft 5W-20 synthetic blend year-round in a Ford modular V8, anywhere in the US.
that is what i used year around in my 2000 F250, no problems at all.
MC 5w20 for a little bit then i switched back to MC 5w30 both with a motorcraft filter. now im using Napa synthetic oil because i bought 2 cases when it was on sale in Feb. when that i done i'll either go back to MC or find another sythetic on sale.
i was using a pennzoil filter and i was getting a huge amount of start up noises and when i want back to a motorcraft filter the noises all went away. The filter is a great deal for $3.67 at my local walmart and $3.99 at autozone.
Can't go wrong either way. I like the economy and simplicity of simply using the widely available motorcraft oils and filters. I even use a motorcraft filter on my jeep and often used them on my Toyotas when I had them. Good quality, available and inexpensive. Pennzoil is great too.
