I have a 99 Expedition (just acquired) which tows trailers and equipment 80% of the time. It has the 5.4 Liter engine.
We operate in hilly terrain, and the year-round climate is never lower than 55F nor higher than 85F.
Looking for oil weight recommendations. It has 5-30 in it now. If thats fine, I will keep it, but if something else is recommended, let me know
thanks
