Modifications To Improve Gas Mileage

[SteveH]

45 mph is about the speed where wind resistance hits vehicles enough to affect mileage. I drove my '01 F350 Powerstroke 7.3 diesel skiing one year and barely hit 55 on the entire trip due to traffic and roads. I got ~21 MPG, which is insanely good, and I have never seen close to that in normal driving.

I don't know, but my high mpg was cruising 75 on highway. I think the trick is no traffic and cruise control. Once your at speed, takes not so much gas to maintain. changing speed is the killer.

Our LCs/LXs is pretty much computer operated especially fuel-to-air ratio and delivery. If we are able to do a baseline that our sensors are working as designed, the ECU should be able to adjust the correct fuel delivery in respect with how much air is going in and temperature on the cats to either advance and retard the timing. That said, periodic check up on the MAF, O2 sensors and lastly spark plugs and coils can pay dividends long-term.

No complaints with 16 MPG highway. Little things that seem to have made a difference.
1) SCS F5 wheels and tires that weigh 74 lbs total. Roughly original factory wheel and tire weight.
2) Gamiviti rack. I think the faring actually helped mileage.
3) New O2 sensors installed two years ago when I bought it. Also, was with coils and plugs.
4) Healthy Fuel system new fuel filter, pump, clean injectors. Replaced many vacuum lines also.
5) I think the Valley Tech Bumper helped with mileage. It certainly didn't hurt it.
