Advice on gas saving on small up slope?

[karl lee]

Hi all,

Like to check with you.

Which is saving more gas? During small up slope(hill) is better to maintain rmp Or MPH that save gas(Auto transmission).

Thanks.

Steady pressure on the gas pedal. Let the speed drop off. Get a little runny-go before the hill.

thanks bro,

Can I said that to maintain the constant gas padel through up the small hill? Don't care about speed drop. Could you help to explain this "Get a little runny-go before the hill"?

Use the hills to your advantage when you can. At the crest of the hill and the beginning of the downhill stretch, give it a little more gas to allow the car to accelerate where it is easier to do so (you'll get more out of your little burst of accel). Gain maybe an extra 5-10 mph on the downhill, and then go back to light throttle and let 10-15 mph scrub off as you climb the hill.

Think "rollercoaster". Let gravity work for you to gain speed when you're going downhill.

Never try to accelerate uphill when driving for max economy.

A southern U.S. colloquialism for "Pick up a little speed first."
A running start.

In my area nearly all the hills are `rolling' and very much like a roller coaster. Most hills have at least a slight downslope on the approach or 50m or more of flat.
Slightly accelerate here and up the first 25%-30% of the hill.
Then back off a touch and hold the gas light and steady. (dropping 5 - 10 Mph when reaching the crest)
Accelerate briefly over the crest and on 10% of the downslope.
Coast the rest of the way down.
Just before the flat go back to holding the gas light but steady.

It takes a fair amount of practice to do it just right. But if you cross over the same hill every day you will get it, and will do better than trying to use `cruise control'. (by your driving or with actual cruise control)

Having a Scanguage or similar Mpg readout device can really help to get your driving tuned in with your daily route.

I wonder what part of NH you're in? Very few "rolling hills" where I am more like small moutains. LOL
