Your personal records
 

Hi,

To give us some challenging objectives in 2009, I propose you to cite your personal records in your hypermiling/ecomodding experience.

This can be something as simple as "I didn't speed over PSL (Posted Speed Limit) during a full week ;)". The most interesting imho is the different steps you think they were important milestones in your hypermiling/ecomodding experience.

I begin :

• I coasted in neutral for a total time of 14 minutes during a 26 minutes trip, ie 53% :turtle:

grrr... I need to rig up a stopclock!

475 miles on one tank is mine - within 50 of probably the world record for my vehicle.

Your "step on the moon" or "first kiss" moments...
 

It can be any kind of record, not necessarily measured by mpg. It can be a record that you beat since but you remember that moment as a great one, may be that changed something... (if so then tell what).

Here are a few others :

• First week arriving before 8:05 AM in office every morning (always 1st in my company and once 1st in the building) and got no morning or evening commute lasting more than 55 minutes.

• First coasting in neutral on 1 km with tires pumped-up at 3.0 bar (44 psi).
• First coasting in neutral on 1.6 km with tires pumped-up at 3.2 bar (47 psi). On this segment I'm currently coasting only on 1.2 km because I use a slower max speed as the last 400 m contains 2 round about that are generally under traffic.
• First heavy use of pulse and coast in neutral in city with tires pumped-up at 3.5 bar (51 psi = max sidewall). I had the feeling to fly... since I want an hybrid conceived to stop the ICE in such situations (I don't feel comfortable with the idea of stopping the engine in my current cars : the steering wheel and the brakes are too hard when not assisted).

• First commute with 12 engine stops instead of idling. Before that I was stopping only 2/3 times before worrying too much about the battery, now I can stop 5/6 times before beginning to worry.

• The first EPA+50% (52 mpg) tank in megane with rear wheel skirts.
• The first 50 mpg tank in megane without rear wheel skirts.
• The first EPA+40% (56 mpg) day in scenic with full grill block and wiper cover.

• The first 1000+ km (620 mi) tank in megane then in scenic. Now I know that both trip odometers display only 3 digits... I also know that coasting in neutral is efficient.
• The first 1100+ km (680 mi) tank in scenic. Now I know that I can be more consistent in my daily commutes, but also that a single trip in city can kill your tank.

• The first time I made a trip last 10% more time and saved 30% gas compared to what I was doing previously on that trip.
• The first time I didn't took the highway and consumed less gas than through the highway.
• My first 400+ mi 3 days trip at 53 mpg in scenic with wife, child and lots of Xmas gifts, included a 64 mi leg at 59 mpg.

• The first 900+ km tank by my wife
• Our first 50 mpg shared tank my wife and I in the scenic.

• The great feeling of having a cleaner car when you change air&oil filters and oil from 10w to 5w.

About the coasting time, I have only 2 hands : one on the wheel and one on the manual stick; so I used 2 methods :

• my wife activating a stopwatch when I was saying stop (in neutral) and start (in gear), but she didn't really appreciated to be used as such and so she got the feeling the trip was never ending...
• a voice recorder

I tried to count orally a couple times but when traffic is too heavy I can't concentrate me on traffic and counting. Anyway when you are at "two hundred and seventy seven, two..." then you spend more than one second per second...

My step on the moon moment was when I hit 777 km at the half tank mark during my record back roads turtle run.

I drove 1000 km (620 mi) at 70 km/h (43 mph), 7 hours per day for 2 days, ending just shy of 80 MPG. I remember a lot of the scenery from that trip. I had plenty of time to look at it. Adrenaline moment of the run was when I was in the mountains near Mont-Tremblant, 135 km/h (84 mph) during a coast down appear pretty damn fast when you've been driving 70 km/h for a couple hours.

My biggest achievements for driving last year was slowing down and coasting to stop lights. I live in a reasonably sized town (170,000+) so if it's busy I don't go to slow as to impede traffic, but on my morning commute I can get really good mileage by taking it out of gear while going down a few hills, and coasting to stoplights to let them turn green in front of me.

Next week I would like to start using my scangauge to track my trips to and from work to see how changing certain aspects of my trip change my consumption.

My biggest achievement so far has been getting just over 30 mpg over 326 miles on a recent trip. Hoping to push it up to 35 mpg with a little work.

32.8 mpg on a 500 mile interstate trip (This is for a full-sized Volvo wagon)

• 65 mph
• night driving (no A/C, little traffic)
• windows up
• front air dam
• tires at 40 psi

Record trips in the Celebrity, the last tank of last season.
43.12 mpg over 149.6 miles
40.56 mpg over 269.75 miles
Also getting 35 mpg to work and back the last few days before parking the Celebrity for the winter.

I increased my average mileage in my two cars 25-30% without spending a dime... and that's just since August.

Oh, and I'll save even more money this year by replacing the Clunker with a '95 Civic VX instead of the Prius I was originally looking at. :-)

Since a couple weeks I have a shorter commute (9 mi. instead of 20). Since a couple tanks I pulse and coast in neutral (engine on) at mid speed (40-55 mph) : http://ecomodder.com/forum/showthrea...55-a-7097.html .

During last 2 morning I looked at distances coasted when I'm at mid speed. Out of 12.5 km (7.8mi.) I coasted 7.5 km (4.7 mi.) ie 60% :)
I just look at the odometer when I put in neutral and leave neutral and I mentally sum up the distances. Results yesterday and this morning were coherent : 7.6 and 7.4 km.

Denis.
