We use it at my work on heavy Ford chassis. motorhomes, delivery trucks etc, they are under a pretty heavy load and have never had an issue from any of out customers. I let the local dealership use it in my 17 FFS. When the warranty is out and Im doing my own perhaps Ill switch. But in the Trade Ford blend has a pretty good reputation.Does anybody know how any of these oils being discussed compare to the Motorcraft semi-synthetic Ford likes to use for the prepaid oil changes? I ask because that's what my car is getting (at least until my prepaid oil changes are used up).
