We have a 5.4, 4wd. We do pull our trailer with the overdrive off. The RPM's run about 3000 for us. What we do notice is a significant drop in our gas milage. Without a trailer, we get around 16 - 18 mpg. Pulling the trailer, we get around 8 - 10. We do regular maintenance, fluids, plugs, etc,. We run 91 octane, and travel @ 55-60 mph when pulling. Any other ways we can gain some better gas milage? |
