How to Hypermile.

Subtitles for first section:

What do you see here? A tanker, cars carrying people to and from work. A work truck, maybe. This is what keeps America rolling. With gas prices like these though, this is becoming an expensive problem. In time, alternative energy will come online. But what can we do in the meantime? Suck it up or try to cut our cost as far as possible?

The answer is hypermiling...



DWL section:

to cross out of Ohio and get into Kentucky. As you can see there's a long hill ahead of us... 5% grade. How you deal with this is DWL, drive with load. You see truckers doing this. They lock in a certain engine load and climb the hill. Lose some speed while doing it, though. Hypermilers do it for fuel economy...

The advantage of DWL over cruise control is that a human being can know when there's a hill ahead, and can compensate. A computer doesn't know this. When it hits a hill it suddenly has to go wide open to compensate, burning much, much more gas to maintain speed.


Just scratching the surface but it's a good start.

When I start the car up everyone starts honking at me because I'm not rocketing away from the light. Also does the restart of the engine take more gas? I heard it takes 2 cents to start you engine for the initial fuel burst.

If it's a four lane road or more it's their damn problem. They can go around. If they can't go around, I'll give it a little more gas as courtesy to them, up to but not over the speed limit.

Modern fuel-injected cars take a very small amount of gas to get started - only five to ten seconds worth of idling. If you have a manual and you're rolling a bit then you can pop the clutch and burn nothing :)

What do you mean "Engine Load"? Do you mean having stuff in you car for weight? You told us to clean our car of items that are unneeded right?

[LameBums]

Engine load is roughly how much strain is being put on the engine, typically measured from zero to a hundred. It depends on how much throttle you give and how much torque the engine is capable of providing at a particular RPM's. That's why if you accelerate hard in high gear at 30 MPG you'll just lug the engine.

The ScanGauge has a display for engine load (LOD) which you can activate and keep on and track in real-time. For example climbing the hill in the video, I use 55. It can vary though.

I see your in the Cincinnati area. Beachmont Ave. Crossing the bridge into KY.

[donking2000000]

dont switch off your engine when driving to save fuel, that is nuts. ease off gas pedel when you can, or press gas pedal as less as possible to maintain speed.

@decamerondix

yeah seriously. he needs a prius. it has regenerative breaking and the engine turns itself off when its not needed.

[Wingkil]

Too bad you'll die driving without the A/C in texas in the summer.

[decamerondix]

this is extremely dangerous-you shouldn't be foregoing the use of brakes or turning off your engine while driving-no amount of fuel economy is worth this recklessness

[MrAverageGuitarist]

Where do you get one of those devices you use to measure the MPG?

[deepthoughtsofdeath]

The only minor drawback I could see to taking corners without brakes would be that with a front wheel drive car it tends to really scrub the tread off your tires.
