Mpg's
I just checked the MPG's on my '88 F150 supercab. 4.9 5 speed manual a/c off 150,000 miles on it. Combined city/highway was 15. Is this normal? I really don't remember what I got many years ago when it was newer. I don't have a bed cover or shell on it.

I've been doing mileage on mine for the last 5 months...
'92 4.9L 4x2 extended cab, short bed
Super cold days, the worst was 13MPG. On a mild day my best was 18.75MPG. And what I get most of the time is 16-17MPG. Just got 16.16 tonight when I filled up.
BTW - No bed cover either and 125,000 miles.

92, 5.0, AT, Reg cab, no bed cover, normal driving in traffic..16-17mpg. Filled the front tank yesterday...14.118 gals...odometer read 224.8.
My opinion on a topper is if it is higher than your cab it will affect mpg. Simply from air drag. These year trucks aren't real "aero" anyway. I used to drive with the tailgate down and have had tonneaus on other trucks and never saw any appreciable difference in mpg. ...but even 1 mpg is significant with todays prices!!

Sounds like my 15mpg combined city/highway isn't to far off. Maybe changing the plugs might help. After all, they have about 70,000 miles on them.

Last I checked was 16mpg ('94 300I6 Supercab auto 2X4 203K, all stock). I stopped checking a couple years ago. I bought a motorcycle last year.
