Yes - I do care to share!

Using Hypermiling techniques, I finally got a great fuel economy number - 40.97 MPG.

Here's what I did this tank:
Shift at/below 3,000 RPM (tried to shift near 2,500 RPM)
Pulse & glide technique (see above website)
Shut off engine at long lights
Increased tire pressure to 50 PSI. My max sidewall is 51 PSI.


Now I just need to buy a ScanGauge so I can improve my fuel economy even more.

 

THAT CANT BE SAFE!

 

nothing wrong with 50 psi...the ride is just harsher. i autocross with around 50 psi...

 

Congrats! Get in on the ScanGauge II Group Buy

 

Nice work! I realy need to get my Scangauge. P&G really works well, but hoepfully the SG people can report on what other techniques can bring up the average.

 

I usually get around 35mpg from regular city/highway driving (mostly city). I don't drive fast and I don't drive slow, just normal. But I got 39.6 mpg this past weekend driving from Cerritos, CA to Berkeley, CA (pretty much all highway). Used none of those weird techniques "hypermilers" employ. Here is what I did.

-Cold tire pressure at 34 psi (because I don't see a need to overinflate by ~20 psi).
-Did not use cruise control.
-Kept speed between 70-80, drove at 71-ish almost the whole time.
-It was raining on and off and lots of wind pushing the car sideways, maybe tail-wind and head-wind too? I have no idea really, i was inside the car.
-Engine on the whole time (still think turning off the engine to coast is ridiculous).
-Kept car in 5th gear but threw it down to 4th gear three or four times during uphill climbs around Lancaster.
-87 octane in the tank


The moral of my story is, don't go out of your way to get big mileage numbers. Just drive it like normal and you can achieve greater-than-advertised mileage! And even if you don't, WHO CARES! It's just a few mpgs! Haha. Well that's my opinion.

 

OK I need some Fit facts on P&G. I'm up for it, but wondering some details.

On those that use it what speed (top and bottom) and time from peak to peak did you use?
With the engine off, how did the steering work?
Did you have to leave the ign on to keep the wheel from locking?
Did you use the starter to bring her back running (every cycle) or drop the clutch in 5th?

Lastly what kind of gains can this produce?

I just read this article and this persons says he has a scanner and gets 59 but never really said what he actually got according to the scanner when P&Ging.

My gut feel is in a fit this would be a fair amount of work if the cycle was 2x per min and worse I think aspects of it will hurt the car over time.

 

Here's all I have to offer

hope it's of some help

 

- Depends on the road/speed limit. 60 to 45 worked for me.
- The power steering continues running as long as you keep the ignition ON with the engine stopped.
- You need to turn the ignition back to on after it spins down, or your P/S and odometer will stop. The wheel will not lock unless the key is turned completely off to the lock position
- I use a slow gentle clutch bump to restart in 5th.

I get 6 MPG over my normal driving with a mild P&G technique. The very first time I tred it, it was a new tank record. During the summer I hope to get at least ONE 50 mpg tank.

 

6 mpg wow we nice going

So 45 to 60 and back
when you say +6 mpg was that compared to no P&G and at 52.5 the avg of the above?

How long between peaks? time???
Do you do this on a multi lane road with traffic?

I could do this on the Turnpike but it would have to be 75 to 55 ( I cruse 5 under now at 65) and I'd guess some cars will be PO when they pass me at the bottom and I speed up and pass them back. In fact if I happened to get close to a car going at the avg that could go on for miles or until they run me off the road.

I may try this AM and see what my scanner saws for the trip.

 

the +6 MPG was compared to my winter average which was hovering around 38-39. The first P&G tank was 44.8 in some terrible conditions about half below freezing and at night, and a good portion city driving with 4 people in the car.

Here in PA there are a lot of hills. Even at 50 PSI in the tires, the Fit simply does not like to glide. so I timed my glides with the hills. slowly reach the target speed on a flat or uphill portion, then cut the engine at the crest to make the glide as long as possible.

on CleanMPG someone who is better at P&G than I am, suggested doing it the opposite way - accell downhill and glide on the uptick. I tried a couple times, but goes uphill the Fit simply wont glide long enough to make a forced auto-stop feasible. It's like 10 seconds from
60 to 45 going up an incline.

Yes I only do it on a multilane road, I wouldn't want to hold anyone up.

I would avoid touching 75, that is well into gas-sucking VTEC territory. at the most I'd start the glide wherever 3300 RPM takes you.

Edit: I see you have an Accord V6 as your other car. so I'm sure you've seen one of the modeators on the CleanMPG forums getting 48 MPG lifetime average out of his. I'm sure he does everything in the book!

 

I'll try it Friday. Accord is the wifes. I rarely drive it. It's a V6 Auto gas hog

Nice deal on the scanner is I can see results on every trip and do not have to wait till I fill up.

 

Does anyone else find it real tough to shift under 3,000 RPMS when coming from a stop at a traffic light - in terms of other drivers? They all run up on me, and regardless of what lane I'm in, I usually get passed on either side. Then I catch up down the road a bit.

 

Dead on. Jordon, That is the main reason I can't do any better than 38mpg.

I have to respect some reasonable acceleration rate and speed or deal with road rage from drives in a hurry that could care less about Eco.

That said, I do shift no later than 3k when in the ECO mode.

 

whats a ScanGauge? sry noobie

 

I usually do ok shifting at 2500. but here in PA theres always hills so it varies.

 

There's plenty of info on the scangauge here, please do a search.

 

I sometimes wish I had an auto, but nope mine is 5 speed.

 

Same here, the way they're RIGHT on my behind and passing me on either side it makes me accelerate more than I wanted to. Some of these people driving SUV's seem to floor it from a stoplight for 4 seconds and then let off, what a waste of fuel.

 

Yep I see that. Don't let yourself be bullied into going faster. It's looks as though the people with the least efficient vehicles drive the most aggressively.

All I can do is shake my head while I'm getting a record tank of gas, and a Jeep grand cherokee nails the gas going up hill at 80 with all the windows down to get to the red light before everyone else.
