First week of Hypermiling yields 44.4 MPG!

[Buxton]

One week of hypermiling, and I've improved the MPG by 12 miles!

This week, I did 200 miles on 20.7 litres of fuel, which is 4.5 UK gallons.

200 / 4.5 = 44.4 MPG.

I'm astounded, I even forgot to do hypermiling sometimes, and my route is a lot of mixed villages/towns/dual carrigeways, even a few traffic jams. I'm astounded, seriously.

I think I can get 50 without even being extreme.

I've not even serviced the car completely yet (oil, leads) and I was driving around with a few sets of brake discs in the boot for half the week.

show off, i was driving under 39mph for months...

How did you do your calculations? Did you you do them manually or rely on SGII? I had my SGII telling me that I was getting 34.xx mpg to the tank on my S2000, but when I filled up from the same gas station/pump and manually calculated the mpg it was 30.27 mpg. Ofcourse, this was before I calibrated the SGII. Now that I have it calibrated, I am hoping that my manually calculated mpg matchs the SGII tank mpg.

My readout (car readout) says i'm doing 30.8 mpg. I don't have a scanguage.

I worked it out as:

£22.55 spent

£1.08.9 per litre

20.7070707 litres

20.7 litres / 4.54609188 (UK imperial gallon)

= 4.55491689 gallons

200 miles / 4.5 gallons = 44.4444444 mpg



Working it out in US gallons appears to be a bit worse though - only 36/7 mpg. Oh well, either way it's a definite improvement.

nice job man!!!

what techniques are you using?? P&G?

also, what kind of car? transmission? etc?

keep up the good job, once you get to know you routes better, u will get even better...i used to get 35mpg before hypermiling, first tank, i improved to 45mpg; once i got to know my route, i could get 50mpg w/o even trying, high 50's low 60's...

Thanks man, it's a 1998 Cougar (New Edge) MTX, 2.0 Zetec. The only thing I've changed is accelerating a bit smoother and rolling to a stop in neutral. The car rolls a lonnnnnnng way, I think it's really aerodynamic.

nice, a buddy of mine has that car, he doesnt hypermile it...but hes slowly asking tips for beter MPG, so maybe he'll start one day!

i know that rolling to a stop in neutral can let the car roll a long way (or in your case a lonnnnnnng way hahaha ), but if you leave it in a higher gear (lower when the car isnt as warmed up), it actually cuts the pusles to the injectors, and therefore ur not using any gas, but the trans/eng is slowing the car down alot more...

have you tried to use smart braking at all for the lights that are on your route?

Keep up the great job man!!

Congrats on the improvement, Buxton.

That's likely the biggest help, for sure. Driving without brakes, some call it. Forces you to only feed the engine as much fuel as is needed to get to the next deceleration, and anticipate conditions much more than the average driver.

I agree man, it makes me think twice about pushing the pedal, since I have to change gear. I usually wait another second to see how it pans out and often I can keep rolling .

I'm going to try both and see which is better. My parent's taught me to use engine braking (apparently when they learnt to drive car's brakes were so bad you had to aha).

For the smart braking thing - I only come up to two traffic light sets on my route (it's mostly roundabouts and slip roads). On one set you can't coast or slow down since you have to keep you speed up, because it's crazy four-lane merge and a blind traffic light. But I have learnt to coast up to roundabouts and only brake at the last minute if it's necessary.

One thing I've found is I can really break up traffic jams. By stopping the stop and start by travelling at a constant lower speed I can keep the lane moving, it's awesome!

I've always wanted a New Edge Cougar. They are beautiful.
