Interesting.... Just got myself a new/used Expedition. Basicly a rebodied F-150 and I'm hoping it will get better than the 10.5 I got with the old E-150 van.
A TSB came across the either a few weeks ago telling us to inform our customers that some of the engine performance/mileage concerns are directly related to fuel quality.(duh)
It contained a link to this page. Top Tier Gasoline
The thing I found the most interesting is that some of the gas companies who advertise how clean and green their fuel is aren't on the list. Take it for what it's worth.
Strangely enough Phillips is one of the cheapest in the area, is on the top tier list and works good in the wrecks I drive.
Just my two cents,
