Km/Miles per tank fuel

I was wondering what others are getting per tank of fuel, what ever your driving habits are, and what size you fuel tank is. If you can, tell me the Km, as im canadian and our canadian miles are slightly different then US miles. Im just wondering how bad mine actually is, I will average 400 - 475 Km per tank of fuel with 36" tires and 6" lift on a 98Litre or 26 Gal tank, with mild tune and straight pipe with intake.

WOW, that seems low. A Km is 2.2 US miles i believe. In town i get about 300-350 miles a tank (filling up with about 17-19 gallons) in the warmer weather like now. that turns out to be about 660-770 Kms. On the highway I get about 400-450 miles per tank (filling up about 22-23gallons) and that turns out to be 880-990 Kms. I have a 26 gallon tank too. I know in canada the imperial gallon is bigger than the US gallon too. One thing to note is i have a LB7 and they are known for getting some of the better mileage out of all the duramax engines and i have no emissions stuff on it either. I also dont have 36" tires either. Is your speedo recalibrated for the bigger tires? If not you are traveling further than the 400-475 Kms so you may be getting better mileage than you think.

Yes EFI Live does have that capability. I'm sure he did correct for it, but i know i have issues with my Predator actually getting the speedo corrected on the first load. Normally i have to go back and edit the parameters for the tires after loading it and then it asks me if i want to program the truck with it that way.

Km/Miles ---Gallons

You are using somewhat faulty conversions.

A mile is 1.62 kilometers. It doesn't matter whether it is USA or Imperial miles.

A USA gallon is 3.78 litres whereas an Imperial gallon is 4.5 liters.

I have a 2005 Silverado CCSB 4 WD and on a full tank I can go slightly over 450 miles of all highway driving if I stay at 60 - 65 mph.

Hope this helps with your calculations.

I get anywhere from 400 to 600 miles to a tank depending on speed and city/highway driving. Mine will knock down 21 on the highway if I keep it at 72mph. Yes 72 is a weird number but that is where she likes it.
