your tires and the frontal area of your truck are larger than a Rubicon so I would not expect to be the same.
I have 4:10 gears what comes with the Max Tow. So your saying that because I'm running larger tires and have a larger frontal area I'm getting better gas mileage than a stock Rubicon. That's doesn't make a lot of sense to me.
‘No I thought you weren’t getting as good mileage. Sorry for any misunderstanding..
My bad as well. I was thinking there was some confusion there. All good.
Yeah gas mileage isn't a concern for me either. But if my stock JT was only getting 14-15 MPGs I would be concerned. My Heavily modded 2010 JKU with 3:73 gears got gas mileage like that, even was able to get up to 17 on the HWY with it. I can't see how a Rubicon would get such crappy gas mileage.
Look I don't know what to say or tell you. I can't explain why a stock rubicon doesn't get as good of MPG as your almost exactly spec'd to a rubicon JT.
The wrangler lines come down to gearing, that's why the difference in MPGs. Some are 3.21, 3.73, and 4.10 gears. A wrangler with the same gears stock, 07-11 will have pretty much the same gas mileage, 12-18, pretty much the same and 18-20 the same. I haven't saw Jeep wranglers with the same gear ratios with 2-3 mpg swings stock. Across the board they are pretty close to the same when modded as well. It seems strange that two JTs with the same gears are getting such different gas mileage. I still think tuning from the factory has something to do with it.
I'm not sure unless it comes down to the towing capacity of the Max Tow. I do know that when I tuned my 2010 Jku to run higher octane gas it bumped the mpgs up some. Even when I just ran the 87 octane tune with the Superchips Flashpaqs, I saw a 1.5 mpg increase from when I just had it recalibrated for tires only. I'm just guessing as far as the JT and Rubicon vs Max Tow goes. I am not an engineer but I feel like it has to do with how it shifts or tuning.
And I might add that I'm kind of a lead foot, and the exhaust sound the Gladiator makes does not make it easy to be lite on the throttle when the light turns green.
Comparing MPGs is silly. Perhaps you don't realize that MPGs is not an exact science unless a robot drives each vehicle the exact same way on the exact same roads. You never got below 18 MPGs is like me saying my electricity bill was never above $50. WTF does that even mean?
It means my average or anytime I'm driving the vehicle it Nevers averages below 18 no matter where I'm driving. I keep track Everytime I get in the vehicle, for business purposes, every single time I drive it. All of my vehicles are registered under my business so I get a good tax deduction on this stuff. The jeep has never been below 18 and never averaged below 18 on any drive I've done. That's what it means, not even when my wife drives it. The trip gets reset, not the average but the other screen trip that averages each drive.
Please - this is silliness. If you drive downhill at low altitudes you'll always get great mileage. If you drive up hills and mountains a lot you'll get poor MPGs.
