Mobil 1 website says, Mobil 1 EP, which provides protection for up to 15,000 miles, is "suitable for cars, vans and light trucks." There is also this chart: http://mobil.co/1Pd0YAi
The Mobile 1 website will also provide recommended products for your specific vehicle, but the drop down list for Ford gas engines stops at F-350. My 2004 class C is an F-450, so would Mobile 1 be appropriate for my motorhome?
