Hello all, I am posting for a friend who is new to the Hypermilling game. Here is his situation. My friend got a job in the heart of our capital, Washington D. C. I helped him load up, and now I am trying to school him in fuel saving techniques. I would love your input on this one. http://www.uhaul.com/guide/index.aspx?equipment=truck-10 GMC Truck "Mini Mover" however has a nasty drag creating box. Fuel * Unleaded fuel * Fuel tank capacity: 35 gal. * Miles per fuel tank: approx. 420 * Miles per gallon: approx. 12 We need to go 1082 miles. I figureed this will cost about 540 USD at average of 4.11ish prices. I figured at 15 MPG we can do it for 256 USD. How can we get this beast to conserve?? Tires: It has 80 PSI "recommended" Max side wall 100 PSI tires, however the condition of the tires are moderate with wear on the drive tires. Scangauge II does NOT work with this model of vehicle due to a block they put on the OBD II port. What else can we do? We assume we can get maybe 15MPG or more @ 55 MPH. (But UHaul assumes you do 55 for 12 MPG) NEURAL will NOT allow you to coast far, due to the dynamics of the vehicle. We are FULLY loaded. Recommendations? Any experiences? Thanks everyone, I love this forum and community!
