I'm going the other way-ANYTHING but the Motorcraft! The MC dino/synblend doesn't agree with my company Transit 250 3.7, at all. The Pro DS is good stuff, and seems to be cheaper than the other 2 (usually).
I know it sounds crazy but I just couldn't make up my mind. I called the guy who does our oil analysis and asked his opinion. After hearing what he had to say I'm going with the Pro DS and a Wix/Napa gold filter for 5,000 miles.
