18 hwy (65-75mph)unloaded

15. 5-16 (city/mixed)unloaded

15 hwy towing 3500lb boat (stock) Haven't towed boat again since bombing





I used to get 19. 5-20 hwy and 18 city until DDII's and EZ. Mileage went down due to heavier foot w/BOMBS... .

My Fuel Economy

I have a '99 Ram 3500, 5spd, 3. 55LSD with 235/85R16 tires. I average 16. 5mpg unloaded average speed 70mph. I average 14mpg loaded with 10,000+ pound trailer with an average speed of 65 - 70mph.



MPG calculations by hand, taking into account 235s instead of the factory 215s.



Hope this helps.

[kebees4]

Best ever after 430 miles highway one way @ 65-75 MPH 18. 5.



Normal mixture of driving otherwise is 50% highway and 50 % back roads 15. 5-16. 5 summer with no load and when pulling 2000lbs trailer it falls to 13. 5 MPG all figured with calculator not computer. Winter fuel seems to have little efect on mileage. I have never gotten the mileage most people say they are getting.

My great web site



With 99 2500 4WD 3. 54 rear end Amsoil lubricants throughout and Amsoil air filter I get:



17-19 in hilly country unloaded driving

19-20 in flat land highway unloaded driving

12-13 in flat land towing about 8500-9000#



This is with CA fuel. Add 1 MPG for out of CA fuel.

Loaded (w/ 10k+/- behind the truck - that's about 18k GCWR)



Highway = 16mpg

Hope this helps.

Does not seem to matter if I'm driving city or highway on the fuel until my wife gets behind the wheel. No guages, no nothing in this one.



95. All empty miles.



Running flat out all day long on the highway with no load, 17. 5

City 15's.

Slow down and drive 55 in the 21 range.
