optimistic about 40mpg - Fuel Economy, Hypermiling, EcoModding News and Forum

my usual economy is around 36mpgs. today t he average economy that's on my Android Tablet + blue tooth OBD I managed 40mpgs. I was doing an agressive pulse and glide, accelerating to 95kmh and coasting to 88kmh the entire trip, even uphill . on down hill sections I would try to accelerate to at least 100km/h quickly and then glide as far as possible but not below 88 M y instant economy would drop to 9 mpgs on acceleration and rise to 73 mpgs while gliding. with my regular style of driving my Tablet shows average mpgs and my tank to tank average is 36. so I am confident that the that's is pretty accurate. I doubt my tank average will be much different since this was one day of driving, one half of my trip. I am really happy with my economy but worry about all the shifting on my automatic transmission

sorry I mix mpgs and km per hour. I use mpgs on my Tablet because it doesn't show decimals for L/100 only whole numbers. and my speedometer and my GPS are both in km/h

have you done a grill block and aired up your tires?

yep! tires are 40psi and I have an upper and lower grille block.
his weekend I hope to find time for a belly pan! and I am contemplating an airdam that will cover the front lower grill and wrap around to the front wheel wells

i would be careful with the auto trans. i might be wrong, but i just don't like taking risks because it's the trans fails it's about 3000-5000 to fix. you might be better just driving at steady 90 kmh and coast only when your going to coast for a while (not short coasts)

40+ mpg feels good.

it sure does! I can't wait to have a tank to tank average verify it.

Torque for android was not accurate at all with my focus so it's probably the case on yours. It always got me 5-10mpg more than what the car actually did. Unfortunately there's no real way to calibrate it at the pump, that why I bought a scangauge....

Btw you seems to be doing really good with yours, I know 07 got an ecu reflash with 5% better mpg. I really should get an appointment to flash my pcm at the dealer.

Nice work, especially with an auto. I can't seems to get past 32mpg on mine.

i use a program called efficiency that is able to be calibrated. It always matches with my tank to tank, torque is not to bad on mine either. I like the efficiency program because it has a giant colour coded readout. if it is green you are in eco zone, blue you are below. great to quickly correct throttle position with a glance.
