Motorcraft 10w30 is not full synthetic if it matters. Ford recommends 5w40 full synthetic or 15w40 dino for use with bio fuels up to 20.
Also, 5w40 is the oil Ford recommends for severe duty.
Most on other forums lean towards the 5w40 full synthetic oil over straight dino oil.
ĎCanít go wrong with 5-W-40 full synthetic. The cost difference is very minor compared to the cost of these engines or the cost to rebuild them.
