hello to all the technical guys:
the questions I would like to post is:
how do I increase my fuel milage the least expensive way and not void my warenty?
I am getting 20mpg/imperial or about 16.5mpg/us gallon
this is empty and driving about 65mph in hilly country of BC.
any and all help will be appreciated
thanks

Drafting NASCAR style comes to mind.

Tire air pressure, keeping your truck in top condition and general driving style all play a part in fuel milage. No one factor or guru fix will increase your milage.

 

thanks Maxium
I was wondering if there were any little things other than what you have mentioned such as larger more free flowing exhaust.. if that might help

 

Exhaust lowers the EGT's when towing. $$$ spent for mods are what your looking at. Buying an old Honda Accord for next to nothing will improve milage but towing is not an option.......

 

Consider using a fuel additive; you may see a 0.5 to 1.0 MPG improvement, or you may not. In any case it may help prevent future EGR & VGT soot related problems. I see about .5 MPG improvement.

Consider using synthetic oil; some report an improvement in MPG. I plan to try it next change but have no personal experience.

Consider your fuel source; some report better mileage when purchasing fuel at stations that they believe to have better quality fuel; higher cetane. One particular chain (that I use) has received criticism from two articles in an "over the road trucking" magazine for selling "HOT" diesel fuel which as it cools becomes slightly less volume than you purchased.

That is just funny stupid considering the energy to heat and expand 10,000 gals of fuel to improve sales at the pump.......you might consider another magazine for your viewing pleasure.

 

It is hot from the refinery; reported as hot as 98ºF at one station. It is not my magazine, a friend gave it to me since he frequents the same station I do. Looks like the magazine has been around 30 years. On-line version at landlinemag.com There should be two different articles; the last was June 2005.

I tried checking my fuel temperature but believe the IR gun was simply looking through the fuel to my inlet pipe as they (my measurements) were all too close to ambient. Not concerned enough; so I have not tried an actual TC probe. The refineries are not that far from my station and being a large truck stop they go through the fuel at a high rate.

The better fuel economy results I have experienced have also been with fuel purchased elsewhere (and lower volume stations).

But hey, what would I know.

On my 03 a simple muffler delete, and synthetic rotella t netted me close to 3mpg, with my foot out of the tuner SCMT 1704 in economy mode, gained another 1 mpg. I had been averaging about 17mpg on the highway before the muffler delete and syn oil. First trip using syn and no muffler I got 19.7mpg. All numbers are hand calculated, every tank full, since it was new. I also started doing the same on my new 05'. I switched back to conventional oil due to no syn at china mart when the oil change was due, my mileage dropped 1.5 mpg, same trip, same fuel, same speed. Changed back to syn 1000 miles later (china mart got some in) and mpg increased 1.5 mpg, again same trip, same fuel, same speed. Hope this helps.

sssslllllooowwww ddddoooowwwnnnnn

 

IF it is 'hot' from the refinery, I would think the problem would be the retailers--average ground temps where the tanks are should be 70 or less, and the fuel would cool rapidly in the tank--not after being pumped into a vehicle. Guess you could watch the delivery truck next winter and witness the steam cloud off the tanker--that would be interesting.

 

too true....fill up in the early morning when the temps are cooler, and the fuel denser. you'll get more the money!

 

The temp of USTs doesn't change as rapidly as ambient air (usually not at all, that's why they are underground in a controlled environment, and zoning, )...unless the fuel lines and temp of your truck has that much to do w/ it...

 

I always have to snicker when someone who bought a 7000+ lb pickup complains about fuel economy.

I have to ask: What were you expecting, and what do you expect? LOL.

I'm sorry, but it takes a few dead dinosaurs to move these things down the road! The sheer fluid dynamics of it are staggering, esp. with towing mirrors. 4x4, forget about it.

Due to the cost factor of the truck alone, my purchase had to serve both the needs of having a truck and hauling the family, hence the purchase of a crewcab. Since I needed a truck it was going to be a Diesel so gas mileage on family trips wasn't as bad as a gas truck. Compared to the V6 Montero I traded in, I lost about 2 MPG in city and depending on speed 1-3 MPG on the highway, but I got a lot more useful truck in return. Compared to my brothers 1 ton dually Chevy with 454 gasser I double his mileage. I even do better than his new Avalanche. Do I complain about Mileage? Sure. I wish I got 25 on the highway and 20 in the city. I just feel that there could be a little better balance of power to MPG than what I get with the truck. I also feel that the whole "who makes more torque?" war is stupid. My truck has more power than I need. I feel that they should make 2 Diesel options for truck buyers. A fuel efficient one with good power for normal use, and a gas guzzling, brute-force, powerhouse model for those that need that type of truck. So to answer your questions; I got a little less than I was expecting since the 6.0 doesn't get as good of mileage as the 7.3 it replaced and not even close to the Cummins owners I work with, and I expect that a motor that it supposed to be more advanced than the one it replaced get better gas mileage than it does.
