Regular or Premium

[ydopen]

I usually buy where im at, at the time and 99.999% of the time get regular. Now that ive been playing with the Fuelly app on my phone I mite start running the non-ethenol gas here at the only gas station in my town lol. I will also have to refrain from listening to the sweet sound of that 5.4 with the flowmaster on it lol

Premium. The Navigator engine requires it.

What's the difference in the Navigator vs Expedition, why would one require Premium and one Regular?

Navigator has a 4V engine. And I'm guessing higher compression along with it.

For previous generations maybe but the 3rd gen Navs use the same motor as the Expys.

I've tried both, it seems to run better with regular.
