Filled up in the US with ethanol free for the 4.6 and the truck ran noticeably smoother, better throttle response and with higher MPG.
Using 89 octane with 13% ethanol in Ontario was a noticeable difference, the gas gauge was dropping way faster as opposed to ethanol free.
Same route, same traffic ...
It's beyond irritating.
Anyone else of the opinion that these trucks are meant to run on ethanol free?
There's no more ethanol free in Ontario Canada btw.
