LBZ Fuel Mileage

[BlackMAxx]

No, I did not adjust the speedometer for the bigger tires..
And as for the MPG. It was just shy of 23mpg and I got it off of the DIC and I calculated it also.

If you didn't correct the speedo then your actual miles traveled is greater than indicated by the odometer. This will throw both hand calculations and tthe DIC off toward the low side. Additionally, you could now be looking at winter blended fuel.

If you really got 23 at 70-75mph I'm envious. the best I've been able to manage is 22 at 65 mph. Is yours 2WD?

[BlackMAxx]

No It's 4 wheel drive. And I just went out and got the paper that I wrote on last summer. The highest was 22.7mpg. Right after a fill-up and hit the interstate.

I was told by a guy that he had the gasket around the turbo,(not sure which one) had a crack in it, and he was getting very poor milage.

Just took a trip (Ga. to Tenn. and back) I didn't speed and no heavy load. 21mpg. to 22mpg. Stock. Check mileage both ways. The average and miles /gallons. I had order a bully dog before the trip. Just entered the program last night will update later.

I drove from Spring City, TN to just south of the Atlanta airport last weekend. I drove at 60mph on cruise, no a/c, and was very light on the throttle. The DIC said 23.4 mpg. This is the best I have seen and this was a 208 mile trip.

I have an 07 classic (all stock) LBZ 66k miles and I get 12-13 mpg around town and 18-19 on a trip. How accurate is the DIC when watching milage? Mine seems low. I expected a little more, any suggestions to squeeze more mpg's?

[DarylB]

Best tank so far 19.02mpg @65mph crusing speed. Going to slow down a bit more this next tank and see if I can squeeze a bit more out

16.5-17mpg average is the norm for me. 28k miles currently.

Just picked up my 07 and driving home on the flat: first tank 19.5 mpg and the seond tank through the mountains between Nashville and Atlanta on I-24 18 .5 mpg. I was running 70-75 (1900-2000 Rpm) in Drive.

I wonder if I shifted to Manual if the TC will stay locked up better?

How many miles and is is stock? Stock tires, air filter, exhaust, intake, etc.
