Are you a Big-Rig Hypermiler ?...

[Volvo8873]

I just recently started slowing down myself and padding the pedal and seen a signifigant increase fuel milage.

I used to set the cruise at 70 mph and keep it in the very top hole. 70 to 80,000 pounds loaded and small ugly hills. Seen about 6.5 mpg during the summer which is the highest I have seen. Most of the time is and average though of 6 mpg even lower in the winter.

As of recently I slowed down to about 62 63 mph and I keep the top hole split down so the rpms are about 1550. Just by that I am seeing 6.7 6.9 mpg lately and that is with the cruise on! Been playing with the pedal more and seen 7.1 the other day. Seems to take longer and longer to empty a tank! LOL
