When i my 03 hit 3,000 miles i put the motorcraft synthetic blend in (5w-20 what our car requires)
then when it hit 6,000 miles i put in amsoil 5w-20 full synthetic motor oil.. amsoil is th eonly brand that makes the 5w-20 viscosity...and i called for and they said as long as the oil is certified and 5w-20 it will not void the warranty.. so there ya go
