04.5 600 auto mileage

[lcaad1249]

I'm curious what other people with similar trucks to mine are getting. I've got an 04. 5 600 4x4 with an auto w/ 3. 73's. I've got a Juice Attitude/EZ stack and FASS with 315 AT K/O's. What kind of mileage are other people getting. Hand figured with compensating for the tires I routinely get about 15. I've only got 16,000 miles. Anyone modded or not's mileage with an explanation of the applicable truck specs would be appreciated.

You can see from sig how my truck is equiped. It gets in the 15-16 short trips and around town and 19-20 on the highway at 70 MPH. It has got as much as 24. 7, but that is taking very easy on some long country roads. All hand calculated of course. I am starting to look around for tires at this time and have about ruled out the 315's because of the milage factor, with most people observing a mpg loss of 1. 5-2 mpg.

Hello,



I have a 04. 5 with auto and 3. 73 gears 4x4 with 8500 miles. I'm getting 21 MPG hand calc on a 100 mile round trip doing 60 MPH.

Rick

Welcome to TDR. With you having only 8000 miles expect your milage to increase.

I've got an 04. 5 48re and 3. 73's



I get about 14 to 15 in town. On the hwy I avg about 16. 8 to 17. 5. I could probably eek out abot 20. 5 on a long, flat, road at 60 mph.



I had 35"s on for a while, and my mileage dropped so bad it was a no brainer to get them off asap. I think I lost about 4-5 mpg by adding 35"s.

Mine is similar to yours without the FASS and tires. I get 18mpg unloaded (29K mile average - it is typically 18. 5 - 19. 5 at 65mph) and 14-15. 5mpg back and forth to work. The 15. 5 is with the 0 in the corner of the display thingy. On 2, I lose mileage, same with 3, 4 and 5. The jury is still out on 1. Your numbers are reasonable. klenger told me to slow down and I get better mpg, go figure.

I've only had my '05 4X4 dually around town so far. It gets around fifteen MPG, but I've had a pretty light foot lately. Based on my '03 I'll guess my freeway mileage will be about 17 MPG because it's a dually.

12. 5 MPG towing 10,500 lb 5vr over two passes each way averaging 62. 5 mph, done this route 3x and mileage and conditions have been the same. Going solo (w/o) 5ver in a few weeks and will finally see what kind of unloaded mileage I will get.
