My harley truck gets around 16 MPG mixed driving (just under 5,000 miles in 2.5 years)

as far as the procharged truck, I'll let you know about my mileage next weekend got boost? I do, twice

 

I get about 13.5 in the city and a whopping 17 on the highway. Measured the highway mileage on a trip last week. The results surprised me. Thought I was around 15.

 

I'm getting around 15-16 with the procharger, I need to take a highway trip and see how it does on the open road

 

I get a consistant 18 mpg on highway....solid 16.5 up and down the mountain (plateau) everyday. I have gotten 19 once highway

 

I got 20.1 on my 22 mile drive in to work today. Then left work for a 75 mile drive to a different location, driving 65-70 mph, and got 18.2.

I'm at 12.2mpg pure city, haven't checked highway yet. I'm hoping gears will help a little, I'm forking out $1.19 a litre for premium here!

 

15.5 in the city. 19-21 on the highway depending on speed. Higher speed means lower mileage.

Roushcharged. I run it hard every so often, but go easy on it most the time.

 

Finally did a Highway run last weekend, I averaged 18.7 mpg. I figure that's not to shabby for the set-up I have, I went easy out there to check what I would get for MPG, and thrashed it on the way back home! Surprised a couple Hemi's it was great

 

OK, this is obviously very high if your running a 5.4. Guess this says two things, 1 need to dyno tune and 2) Mike is GOD
