Car Forum / Chevrolet / Chevrolet Trucks / November 20072006 2500HD diesel MPG and gallons used in DIC
Anyone know how accurate the readings in the DIC are for average MPG, and gallons used for 2006 model year Chevy trucks? very accurate, i reset fuel used every time i fill up and the next i fill up i look at the gallons on the pump and look at the gallons on the dic they are very close, if you want to see if mpg is correct do this, reset the average economy and one of the trips when you fill up then the next time you fill up divide how many gallons into the miles on the trip it should be close to average economy mine is 06 sierra > Anyone know how accurate the readings in the DIC are for average MPG, and > gallons used for 2006 model year Chevy trucks? by the way what is your average economy on that diesel > very accurate, i reset fuel used every time i fill up and the next i fill > up i look at the gallons on the pump and look at the gallons on the dic [quoted text clipped - 11 lines] > ----= East and West-Coast Server Farms - Total Privacy via Encryption > =---- I've only driven 100 miles since I bought it used and filled the tank for the first time. The fuel guage is at 3/4 full and it's the 25 gallon tank. According to the DIC I'm at about 16 MPG. That is mostly mountain and city driving. When I filled up for the first time, reset all the counters and hit the highway it gradually climbed to 20 MPG at 65 MPH, then gradually dropped to15 MPG as I drove up and down a winding mountain road, then has slowely come back up the current 16 with an estimated 60/40 city/highway driving. > by the way what is your average economy on that diesel >> very accurate, i reset fuel used every time i fill up and the next i fill [quoted text clipped - 20 lines] > ----= East and West-Coast Server Farms - Total Privacy via Encryption > =---- > by the way what is your average economy on that diesel Not Ed but just did about 3600miles on my '06 Dmax---almost all highway with only a few hundred lbs in the box--averaged just over 21mpg running a mild tune!

Well thats better than the 12 i get with my 6.0L gasoline >>> by the way what is your average economy on that diesel >> [quoted text clipped - 3 lines] > > Well thats better than the 12 i get with my 6.0L gasoline Thats why I went to the d-max---and when I pull my bbq trailer(20'--9Klbs) mileage drops to about 14mpg with a kinda light foot! Buzz I returned from a 1000 mile round trip last night. I had my camper mounted and averaged 15.5 MPG for the total trip which consisted of mostly highway driving, several hours of slow dirt road driving and getting stuck in traffic for about 30 minutes because of road construction. With cruise set at 60 MPH on flat terrain, 70F temperature, 3,000' altitude, the DIC showed as high as 18 MPG. A total of 5 fill-ups since I bought it. When I compared the DIC to real gallons used and real MPG, they were within 1%-2%. Pretty impressive. > by the way what is your average economy on that diesel >> very accurate, i reset fuel used every time i fill up and the next i fill [quoted text clipped - 20 lines] > ----= East and West-Coast Server Farms - Total Privacy via Encryption > =---- >Anyone know how accurate the readings in the DIC are for average MPG, and >gallons used for 2006 model year Chevy trucks? Can't say about the 06 model, but my 04 is fairly accurate on both gallons used and mpg figures. I've kept track of all my fuel purchases since the truck was new. I've compared actual to indicated several times, all very close, my last fillup the DIC indicated I used 27.6 gal, the pump agreed, down to the 10th. I do try to use the same routine every time I fill the tank to keep it all consistent. DJ |
