LBZ milage on 1200 mile trip

[Brad Pelot]

I went to pick up an enclosed car hauler, and here are my results as close as I can remember. I have pulled several similar trailers from the same place before, so I know about what I have done previously on mpg.
At 75 mph empty 17.1
At 82 empty 15.0
Pulling 24 foot v-nose enclosed car hauler 11 feet tall @ 80 8.1 @78 8.2 @ 70 10.4 Not very impressive to say the least. I think the lbz goes through about 25% more fuel than either of the lb7's before it. I know some of it is the lift and tires, and it isn't broken in yet, bit I just don't think it is going to be nearly as good on fuel as the lb7's were. Sad but true.

Remember, diesels get better milage once they are brokne in. Usually 25-30,000 miles.

My '01 LB7 with 100K is averaging 12.5.

It always has a 25' gooseneck behind it weighing in at 4500lbs. Average loads are 4-6K. Some as heavy as 10K.

I am very pleased with the mileage and might try to stick with LB7's for awhile simply for their mileage capabilities!

I'm going to check the posts on fuel mileage to see, but I suspect no engine will match the LB7 in Mileage stock, Torque and Horspower Juiced, because of the lack of certain emission components on the engine and exhaust that were added on later year models. Glad I got the 02. I've got a hunch Kennedy agrees.

Thats the one thing I don't want to give up on my 03.

I don't understand why in the world the EPA thinks they are improving anything by adding emissions crap to these trucks if they are making the motor less fuel efficent in the process.

I agree 100% both of my LB7's would pull much better fuel economy than this one, and that is with edge on any setting or off.

On the breaking in process, if you are constantly pulling loads, it will not take but about 10,000 miles or so to get broke in. Heavy laden makes every thing seat quicker.

Right off the dealer lot - and still stock - my 04 lly was much better than my 02 lb7 when I was pulling the camper. Since then I have added different mods to each truck, and switched campers - so I have no way of comparing them now. My guess is that the lly has still got the advantage...

Take off the lift and big tires and you will see the numbers inprove. I think those numbers are plenty acceptable given the speed at which you were traveling.

My LLY is just as good or better than my LB7 on economy...

The addition of 6th gear is not likely going to get you much mpg and the lower revs/noise may entice you to run faster yet further dropping MPG.
