The duramx and the allison have been good but I've had lots of problems with other things. (Transfer case, door locks, u-joints, transmission lines,rear end vibration,)
So I may try a ford. Besides they have not taken any tarp money.
Thanks folks,
Boomer :confuse:
First comes attention to the drivetrain.
Get high quality filters for the engine, fuel, air and transmission.
Replace all your filters.
Use synthetic oil. I like either Rotella or Amzoil.
Add a bottle of fuel additive to the fuel. I like Lucas; but I am sure there are others that work well.
Now check yout mileage...carefully. I like to do at least 4 tansk in different conditions to get a baseline.
Still nto better?
I would suspect the tires.
I can't begin to tell you what a huge diffference tires can make on a vehicle.
Still no good? You might jsut have a truck that is not going to get good mileage.
I don't know why this happens, but some are just better than others.
Thanks,
Boomer :confuse:
Now to Duramax. It is an 07 Z-71, crew cab. The economy is pathetic. Pulling the empty trailer I get 10.5. At highway speeds with no trailer I can average 15.0. I got that with the gas rig, and the fuel was cheaper. I have thought about buying the programmer, but if it's not going to make a drastic difference I cannot justify the $379 expense.
This was my first diesel; and probably my last if this is the norm. It's not worth it both for fuel economy as well as the cost for service.
I'm surprised to see people talking about 19mpg on the freeway and less around town. I can be quite feather footed, but it couldn't make that much of a difference.
I painted that bright red Chevy 2500HD Duramax the prettiest shade of "gone" you have ever seen. I have now officially sworn off of "Government Motors" and chalked this experience up to stupidity on my part.
The Tundra is doing just fine.:)
Both the same size tire. The new tires are a bit more aggressive but still not true mud and snow tires. I wasn't expecting that.
Made in USA but not a name I can remember now like Firestone, Goodyear etc. Its raining outside or I would go look. 3" + and counting.
People tell me I am getting good mileage and I think I do. I think that size of truck and what is towed has a huge impact on the mileage, as well as, how you drive.
At 400hp, I don't think that would be a problem; and I won't have to stop and fill up as often.
Thanks
Can anyone tell me what they are getting loaded and unloaded.....just curious.
Thanks
My current mileage stats are as follows:
Total vehicle miles 6654
Cummulative average 15.38
Best tank 19.80
Worst tank 10.29
Last tank 17.73
I tow a triple set up with my boat and a pop up trailer, total towed weight ~ 8500#
I bought my truck the first week of June this year and used it all summer towing.
My average towing is between 11-12 MPG depending on driving speed and terrain (I live in Utah so lots of mountains).
My average when commuting, mostly hwy is 18mpg.
I haven't done a road trip without towing so can't tell you what that would be. I'd guess right about 20.
Hope this helps.
