Hello from WA state
 

I been lurking around for awhile. I though I would say hi.
And I have a questions to ask.
Right know work provides a E250 5.4L auto it really sucks gas 12.5 city

Personal cars
94 Mustang 3.8L 5 speed I been getting 30 hiway
87 Ranger ex cab 4.0L 5 speed I been getting about 19.5 hiway

Welcome aboard.
To answer your question, drive the Mustang. :) (unless your employer pays for the fuel for the E-250)

My employer pays for the E250 fuel. It costs way to much for any personal use.
Well what I am wounder why some cars seems to glide so well. I just got done fixen a 2.5L ranger 5 speed for someone. It gulids so much better than my mustang and my ranger.
My work van will gulde almost as well as the 2.5L if I put it nutural.
I am guess if I can get the my mustang/ranger to gulde better my fe will increase.
