Check out this GREAT GAS MILAGE I GOT.

[Labswine]

I know I answered this thread earlier but went back through and re-read some of it. Yeah, the hypermile habits might help a bit but, traveling and hitting neutral on a down grade, you'll probably spend more in new brakes then you would on gas. I have tried this once or twice and noticed that I was coasting to well over the speed limit (more than my usual 5 over that I try and stick to) and would need to apply some braking to keep it at a reasonable speed.

What I do is first and foremost is that I have a very light foot. I also keep my tires at 40 lbs.

When I am approaching a red light, I'll shift into neutral and coast up to it and keep it in neutral while waiting for the light to turn green. My gas saving rationale for sitting in neutral is that in neutral, the engine is simply idling with zero load on it. When it's in gear, the 'puter is adding more fuel to account for the load imparted by the transmission therefore, using a bit more fuel.

Also, when starting out I shift the trans manually until around 42 MPH, then flip to regular drive and let it do it's thang. Starting out, I generally start in 2nd then at around 15 MPH, shift to 3rd. At 22 MPH, I shift to 4th. At 32 MPH, it's 5th and then 6th at 42 MPH. It's generally around 2K RPMs at each shift. If I let it do it's own thang, it'll get to between 2,500 and 3K before it wants to shift no matter how light I am on the throttle.

With this, I am averaging just over 21 MPG in the summer and 20 MPG in the winter just bopping around.

Never seen a mountain that was 200+ miles downhill before

Try the Ike down to KC WITH a killer tailwind.

I got 20+ mpg with my 2013 Ram quad cab 1500 5.7 3.55 rear end pulling a 14 foot pop up camper once. It's all downhill, and the winds were strong as we paced a fast moving front.. Best gas mileage I ever got in that truck.

I go up a 6 mile long 7% grade every day to work. What's gas mileage?

 

[devnull]

The key to Jeeps getting 20mpg is 50-60mph. Anything higher and it drops like a rock.

This explains my 13.9...

well that and my constant stomping of that right hand pedal.

Most of these involve some either downhill and/or tailwinds and/or a set speed in the 50 55 mph range. Any stopping and starting are killers on the Gladiator. I've had a couple in the 23 mph range (Gladiator) for 100 or more mile trips. In particular are trips from like Missoula to Spokane with all my vehicles I've noticed. I've got or had Ram 1500's, a Renegade, a Gladiator and a Cherokee with the 3.2 V 6 and 3.21's. The Renegade has gotten the best but NEVER what the sticker has said. I didn't include my 6.4 Hemi 2500. I've driven Ram 1500's with the Pentastar V6 for like a week at a time rentals and they always seem to beat the Gladiator. I consistently got 22 mpg on the highways with those... The Renegade with the Tigershark averaged close to 22 mpg (No where close to its ratings) with about 50% highway and 50% in town as a daily driver. My Gladiator on Summer gas is right at 19 mpg doing the same daily driver stuff.

Oh, Summer gas is another factor and not inconsequential I've noticed over the years.

AND those mpg's on the screen are dynamic over a set number of miles....

And to think if you would have gotten a diesel

That's cheating!!

2020 loaded JTR w/3.6L & auto.

Yes.... it's relatively flat here in Florida.

AND, you get summer gas all the time... I find that winter gas is over a half a mile per gallon difference.

" traveling and hitting neutral on a down grade, you'll probably spend more in new brakes then you would on gas."

We call people here in Montana who do this....dead. The goal is to NEVER use your brakes. No, you take the shifter and move it over to manual and you adjust gearing to keep your speed so you don't use the brakes. Now realistically you will have to but you get good at it.

Let the transmission do the work. I watch flatlanders come up here and ride their brakes down steep mountains. I have actually stopped so I would NOT be the guy behind them when they went over the edge and died and then I had to go look at their dead bodies go find cell coverage, call the police and wait till they arrived. Nope, know people that have had to do that. They are still affected. But those people were getting great gas mileage before they died.

Sorry you hit my hot button issue.

To be clear: Driving over the posted speed limit IS SAFER than driving the posted speed limit IF EVERYONE else is driving over the posted limit.

While and if everyone is doing 80 mph in a 65 mph posted zone... The guy or girl that fly's by at 120 MPH is SAFER TO EVERYONE ELSE than the "hypermiler" going the posted 65.

Wake up please. It's common sense.

Hypermiler folks, please pull your head out of your back side... before someone runs their front bumper up your backside. YOU cause accidents.

While in the Colorado mountains, Pike's Peak and so on, I had it in manual mode the whole time. Hardly touched the brakes at all. The guy at the check point coming must have seen an almost ambient temperature on the rotors.
Somewhere I saw, read, whatever, that going into neutral is dangerous anyway. I always use engine braking when it's not ordinary grades or loads. Maybe that's why I could almost always go well over 100,000 miles on brakes with my cars and trucks?

Lol still you. Nice try though.

Donner Pass to SF is damn close. I just averaged 31.4 driving from Reno to SF over the Sierras on I-80.

I just came up from Sacramento that grade is a fuel sucker!
