What Motor?

I'm shootin for 5.5 with mine 14L 515, 13spd,3.42's Hopefully a lil better but I need a min of 5.5

 

Schneider as well as other ATA carriers means low miles and many light loads, thats why I was asking you about mileage. 308 000 miles means you have brand new truck with no idea about reliability whatsoever, unless you want to tell me its used up and you need another truck now, that would indicate something

What problem you are diagnosing?

 

Engine is an engine, but year of the engine and its transition to EPA regs may have a negative impact on MPG.

Model truck... an Aero vs. Shoe Box will also have slightly different effects on MPG.

Just wondering... because when I asked about the C-15 Bridge many replied with poor numbers. But like it is mentioned above... there are fixes. And since there is not a lot of Detroit info out there thought I would just ask.

Thanks for the numbers. That is the exact motor I am thinking about.

 

It really sucks to post such a obvious things, but you all need to fn learn something abut mpg as it gets really annoying to hear all this widespread BS about mpg.

Huge factor is WEIGHT you are pulling.
Another factor is TERRAIN. Flat? Mountains? City Traffic? High altitude?
Then there is a SPEED - a big one, but only when driving fast, over 60 mph lets say

Without considering those (plus many other factors) discussion about "universal" mpg numbers is pointless, time wasting, air polluting activity

Get it?

 

Were you born this way or did you take private lessons?????

Weight I pull a reefer so I run between 75 -80 thousand at all times my deadhead is less than 15% on avg
Terrain I run southeast,midwest,and ne up to pa,nj,upstate nyc
Speed I run from 0 to 80??? I cruise a t 72 though.

Oh and I run 22.5 lo's you forgot one that affects fuel ol wiseone..
He asked for ball park numbers he didnt want to know what he was gonna get exactly. If you cant produce any decent help how bout move on

 

Now we are talking! Keep in mind, most of the "KR Truckers" cruise at 57mph with 8 000 pounds in their dry van and take mpg numbers from ther dashboard computers (7.9 mpg is "fancy" number lately. You know, not 8.0 - but almost).

I didn't forget about tire size, its completely irrelevant comparing to the big factors

 

When my trailer went in for repairs I had to tow a 4 axle trailer on large super singles tires this made my fuel jump from 1.8 kpl to 1.95 kpl doing the same road and same weight so I would say tire size will have a lot to do with it.


If the trailer wasn't so ugly I would look at buying one

 

You are talking 8.5 % difference. I don't believe you can really measure that without lab conditions. I'm not sayin there is/was no difference, sure it makes difference.

But maybe 3% was method error, 1% was tires and 4% was you? How do you know what was causing what?

 

57???? that put me to sleep just reading that!!!!

Tires have got to make a difference if not there would only be 1 style deep lugs. Not a hwy tread, no super singles and such.

I'm not a single fan but the say there is a big difference. Maybe I tosted it wrong I shouldve put tire size and tread.

Ask anybody that know there is a noticeable diff in a brand new bridgestone lug and a straight tread hwy tire

Oh and how dare you stick you tounge out at me

 

and what is a KR TRUCKER??? did I miss something??
