cruise lowers my millage slightly. I have decided it is cause it slows the truck down when going down an incline.
If I am driving I let the truck roll and get better numbers.
If you not in town, you might not have much traffic.
I have found that if I triple my normal stopping distance when coming up to the light, I can make up any lost fuel millage when taking off.
I let the truck start coasting as soon as the light is in sight, when no one is behind me. This gives me about the same distance at 99 mpg
as I get 6 mpg when taking off. Thus not effecting my average.
Yes... this is going to an extreme and I wont do it all the time. But its kinda like a game at the moment.
Remember, I have had my truck about 15 days. But I have 1800 miles on it.
