I'm thinking of switching oils from motorcraf 5w-20 full synthetic to Kendall 5w-20 full synthetic. It in a 2012 Ford fusion with the 2.5l I4 duratec it has 30000 miles on of almost all highway. All has been great with the motorcraft but I can get the Kendal for half the price. Do you allfor see any problem with this switch, orwould I just stick with the motorcarft. I've been following the maintenance monitor for oci, its bee right around 10000 mi
