Is 10 MPG Possible with a Fully Loaded (80K gross) 5 Axle Truck?

That would be taxes...

 

Cause their profit margin is high enough that they don't have to worry about mileage. They're also fleet trucks. Big fleets rarely experiment with this kind of stuff. I did tell the boss at the company I just left about the microblue stuff. He seemed pretty interested.

 

Are you kidding me.
I would be over the moon.
Okay where I'm from we run a lot heavier but the % gain is impressive.

 

Has anyone tried lowering a truck? The dock plate can easily reach a truck that been lowered a foot or so.

Smoothing out the air flow underneath the tractor should receive some gains in mpg

 

There are lots of custom trucks that are lowered, but I doubt any of them are doing it to gain mpgs. Western Star offers the Lo Max as well.

You are right about cleaning up the airflow, but that would be a BIG job on a truck.

 

Could cause some problems at some of those docks that are down a ramp. I backed into a few with the skirts and had to keep my tandems close to clear the pavement. Or at least just drag the rubber part across it.

 

Yeah , we run lowered trucks here, they are lowered about a foot, they're called megas here and are for high volume loads, no it doesn't help much with fuel, also the cost of lowering them is serious unless you buy it that way from new, for example: to change it after Market you need lower tyres, both truck and trailer, your differentials will have to be changed to suit your tyres and depending on the chassis most likely your front suspension will have to be changed to air suspension!

Alot of people here put pallet boxes under the trailer, not only does it give extra storage under the trailer but acts as a side skirt and has a smooth flat bottom so airflow is smooth and even under the trailer, combine that with side skirts on the tractor should give you improved mileage, the only problem I can see is your wheelbases are a lot longer than ours so be careful not to belly it out on uneven ground!

not only this brakes for low liners are stronger because smaller wheel diameter 5th wheel is different(22+128) on scania you have to use f950 chassis rail instead of f700/f800 or in very rare cases f950 on 4x2 tractors .....


there is no too much savings with this

did you think on extending side cab spoilers here 7cm longer spoiler save 0.5% of fuel at 85kmh ( they are rubber ones) this will be about 0.6% at your 58mph
