gas mileage tricks for manuals

[ptownTSI]

When approaching a red light you can turn the car off and coast, you will coast for a long time without any pumping losses from the engine. before you come to a stop put the car in 4th and ease the clutch out just enough to start the engine, put the clutch back in bring up rpm's and rev match your shift.

guys are doing this and other tactics on www.cleanmpg.com and getting like 70-90mpg+ out of hybrids and 40-50mpg out of accords and civic's its nuts.

i'm starting to do it on my motorcycle. I never realized how long I spend sitting at lights until I was there on a bike with nothing to listen to but the cars whizzing by. so now i turn my bike off at long lights, coast to stops with the engine off and time my braking/accel based on whats going on up ahead, hopefully i can get up to 50mpg in town instead of only getting that when i'm on the freeway.

don't care if its possibly "dangerous" if you need to make a last minute evasive maneuver as my motorcycle doesn't have power anything anyways so its stopping distance is not negatively impacted. don't do it in heavy traffic obviously.

Doing that is actually illegal in a number of states.

uhm. you do know that the ECU cuts fuel when you completely let off the throttle, above a certain RPM (around 1200-1500). watch your econogauge sometime. shutting the engine off to accomplish the same thing seems a little retarded to me.. :p

Plus it puts extra wear and tear on the engine and clutch.

good idea but when the light turns green and you tear through the first three gears and back were you started.

Just like the retards who buy a new hybrid to "save the earth"...fuck...those people should take a damn bus.

The reality is that the building of a new car uses so much more energy and resources than simply keeping a decent 20 year old car in proper tune and driving it carefully.

If we as a nation wanted to make a real dent in our useage of fuel, just make it illegal to use any vehicle over 3500 pounds as a daily driver, or with less than 3 people in the car.

Basically, I feel if you drive anything bigger than a minivan or small SUV, park the bitch until you NEED to drive it to transport your family or workers.

meh, to complicated. I just coast when I'm going downhill.

I honestly LOVE dieseling hybrids when I pass them on the highways in my '05 Ford F250. I pull along the side of them and match their speed and then creep up and make my exhaust(which comes out the passenger side behind rear wheel) even with their windshield. Then I floor it covering them in a huge cloud of black smoke !!! Its worth every dollar it costs .....


Back on topic though I drive the truck as much as the e30 325. But honestly the truck gets damn near the same mileage as the bmw. I get 19-20 in the truck around town and 21-24 in the 325 around town. So the only difference really for me is do I fill a 30 gallon tank up at $3.25 per gal or a 16 gallon tank at $3.25 per gal?

Lol, how about just not going WOT at every possible moment? Or drive a civic.

[ptownTSI]

i daily drive my motorcycle, the e30 sits and my Jeep is a grocery getter/multiple person hauler/Tahoe mobile.

[uofom3]

this seems like overkill to me.

Turn off the engine and coast up to the light then turn the engine back on as you come to a stop? Wouldn't you just be sitting at the light then, idling anyways?
