Just kidding jmorg1980 , Light duty , no oil consumption , 3k mile intervals it would be hard to better the Motorcraft but given the above and the cleaning ability of the new Mobil Drive Clean Plus syn blend and the fact it's offered in a 5w-30 , well it just might be right for you . I think it's 50 cents more a quart than the Motorcraft. Clean slowly while you drive

I like the new Motorcraft because it is near a 12cSt oil to start with . So it's thicker through most of the interval than the one that starts at 10cSt and shears to 9.1 I like the idea of a PAO blend with high detergent and good low temp properties too along with reasonable pricing . Thats why I brought up the Mobil HM oil .
