Cascadia Evolution MPG?

One thing to bear in mind with the truck in the blog I linked to is that it has wide base drives, a 6X2 setup, and the DT12 transmission mated to the Evolution specific DD15, I don't think with the ISX or other transmissions even behind the DD15 that you would see as good of MPG, it is more than just the Evolution aero package that adds to the high MPG it is the entire truck package. If, the DT12 turns out to be a reliable gearbox, in my opinion, most new Cascadia's will be ordered that way and I think we we see more and more that the computer controlled automated manuals are a large factor in hitting the 10 MPG range.

When this 9 mpg is true,is time to change my truck with the fuelsaving now @6.3 -after 9,i can easy pay every month my truck,spend the same money like before end drive a new truck with full warranty.This is not a bad idea

 

If you're going for fuel mileage perhaps you better first find that "switch" in your head. You don't only DRIVE a truck when you're going 65 mph or faster. When you want more miles per gallon you're only going fast when there's a reason to go fast. You'll find out that there's rarely any reason to find...

It also isn't important how much the motor consumes when idling. You just don't idle your truck, only when it's really hot (or cold)... And even then you feel terrible because you actually don't want to idle your truck...

I bet that when you find your own switch you can get good fuel mileage with any truck. A fuel-efficient truck will help, but you're the one that's gotta do it...

Good luck..!!

 

Another plus to having the EPA 14 DD15 engine, is that they drastically reduced the amount of egr going back into the engine. Resulting in better cylinder life, better MPG, and higher cylinder temps resulting in a better burn. The drawback is that more def has to be injected downstream on the exhaust to lower the higher nox PPM counts that the higher cylinder temps create. The DT12 right now seems to be a good,reliable trans. Have not seen any failures yet, but the drawback to that is when something does fail, the dealerships are going to have some trouble at first repairing the problem. As new technology takes some time to figure out

 

4 days or 4 driving shifts?? running 60 sounds possible IMO . but u gotta do what u gotta do

 

That totally makes sense..!!

Don't expect to get 9 mpg though, don't think that's going to happen. But with a truck spec'd right you should be able to do better then with your old truck. But it won't save you a truckpayment per month...

Good luck..!!

PS: Your job would be more then great when you could take the time. 2600 miles in 5 days would give you all the time in the world, save you big dollars and you could do it till far in your eighties...
