My car is coming up on 104000 miles. I've used 5w-20 Dino, syn blend and full synthetic as well as FS high mileage. I generally use the Motorcraft FL500S filter. Ford specs 5w-20. I have a jug of ST 5w-20 FS HM on deck but I was considering to go with 0W-20 and a SuperTech filter for my upcoming OC. It leaks absolutely nothing and maybe consumes a quart in 5000 miles of driving. I don't drive as much as I used to. Mostly around town and highway to the beach on weekends. Recommendations for an 0W-20 or stick with 5w-20?
