Ford engineers have chosen this specification of oil, along with Ford's MotorCraft filters, to ensure that the engine does not suffer oil & filter related catastrophic failure within the warranty period. Ford engineers have also decided, based upon the combination of this specified oil and filter combination, what the oil change interval for your car's engine should be. In theory, if you follow the Ford's recommended service, your vehicle's engine should be fine for 5 years, or 60,000 miles, which is the powertrain warranty. Everyone else will have different recommendations, some based upon fact, some based upon personal bias, some based upon misinformation. Know that no matter what you choose, the oil & filter combination will not guarantee that your engine will last forever. With that being said, yes, there are better oils & filters. This is the part where everybody believes they know which oil & filter works best. This is also the part where some people will simply tell you to ignore the OEM recommended oil change interval, and change the oil every 3,000 miles, 5,000 miles, or whatever. Then other people will tell you to ignore the OEM recommended oil change interval, used XXX brand oil with XXX brand filters, and extend the oil change interval to 10,000 miles, 15,000 miles, a year, et cetera. Like a lot of people, you want your engine to last beyond 60,000 miles or 5 years.
And the "better" Lube's and Filters can't guarantee a thing and from a large fleet which sees a lot more hours of useage with a average of 10 hours a day 365 days a year in conditions which would kill mules bulk oil API SN 5W30 and filters at the lowest bidder prevent oil and filter related failures.

With the UOA's of our 2.3 EB Explorer the Motorcraft blend 5W-30 sheared much more in 4,275 miles than Mobil 1 5W-30 did in 7,000 miles during a similar climate usage or even for 6,200 miles in the dead of winter where the remote start was used way too frequently and too often by my wife grin2. Considering I've been accumulating the Mobil 1 5W-30 for around $11/5 quart jug after rebate I'm ahead in oil purchases for a while grin. Whimsey
