I bought the truck used from a Ford dealership with 64k miles.At 67k miles I started using 10W30.Its only had two oil changes with 5W30 since then.(Ford oil changes)I was wondering if I should switch back to 5W30?I was told being I live in Florida 10W30 would be ok.Is 5W30 recommended for this motor due to tight tolerances or is it a CAFE myth to save gas? ![[Smile]](images/icons/smile.gif)
