Hypermiling - does it work for you?
As a Jeep owner, any help on the MPG count is always an added bonus.
Here's a few tips that will surely help increase gas mileage. A lot of this, of course is common sense.
Any other techniques?
Thanks to jcrowell, bully17 and Spartan99 for additional input.
Here's a few tips that will surely help increase gas mileage. A lot of this, of course is common sense.
- Coast whenever (and safely) possible
- Accelerate slowly
- Shift low, between 2000-2500RPM
- Proper tire inflation
- Reduce/eliminate downshifting
- 45MPH to 55MPH seems to be the optimal speed for fuel efficiency --- driving above 70MPH (give or take a few) seems to hurt your MPG.
- Take it to higher gears whenever possible, even on the streets. Don't be afraid of 5th or even 6th on your city driving!
- Eliminate drag whenever possible - having your windows open/top down is an iconic Jeep element, but hurts your MPG.
- Reduce idle times - some recommend turning off your engine at long red lights (how safe is this? anybody know?)
Any other techniques?

a pic as proof, but its actually about a constant 27-28 round town now
and that isnt photoshopped/chopped either, i have others showing the same on photobucket
anyhoo, back to topic:
I drive normally slightly over the speed limit
I never turn off the engine at lights
I never coast
I do use cruise control but not all the time
I dont accelerate gently. i have a heavy foot that i plant frequently lol!
I do have a automatic Sahara Unlimited with the Hard Top

you must have a diesel... b/c if my mpg was 31.5 in regular unleaded... i would sell my honda and drive my jeep everyday.
oh... and i coast frequently, shift to neutral on long down hills that end at stop signs or red lights, accelerate slower, and try to control my acceleration to prevent down shifting

if I had a big flag on it that said B.S. I would raise it, you must have reset that while coasting...... Even if it was a diesel, I call BS.

honesty FFS - i knew this would happen, i dont even think you can reset the AVG on a euro JK
it is a diesel, i always forget to add that, as my UK dealer wont sell the 3.8V6 petrol unit
and its an auto, the only realy way to coast would be to put in N while moving which screws the auto box - not likely i would do that

Hypermiling sounds dangerous. I know alot of engine wear comes from just the cranking up of the engine. I would gather that the more I have to crank my Jeep the more wear I would encounter. Thats just one point, I can go on for a while about how "safe"/ "smart" this new fad is. Cutting my Jeep off, coasting around everywhere and taking the car out of drive going barreling down a hill does not sound like jolly good tymes, but thats Just me. Good Luck. JOE>

Around here most of our lights have a 45 second rotation so I won't be shutting down but I like the idea of slower starts and coasting it on stops. My last manual calculation was 17.5mpg. Better than my Taho!!! May be I should try goiing above 4th gear as well. I never use 5th and 6th unless I'm on the hyway.

I shift into neutral on many occassions when heading down an off ramp or down a hill to a stop sign. Have done so in many vehicles, including my honda and mercedes. 200K+ on the benz and just under 100k on the honda. No issues.
Where did you get your intel on the nuetral thing?
