do you waste more gas driving fast or slow?

Answer 1

If you look at the EPA rating on cars the highway mileage is higher then the city mileage. Why? Stop and go traffic is horrible inefficient on the internal combustion motor. if you drive and maintain a 55 MPH speed, you will use your fuel more effectively. If possible do highway driving for most of your trips. if your on the roads estimate and look at the stop lights down the road to get an idea as to when they are going to change. if traffic has been flowing your direction for a while it's likely the light is going to change. if cross traffic has been flowing it's likely the light will change in your favor. the idea is to keep the car moving. It takes less fuel to keep a car moving then it does to get the car moving again. I rarely wait for lights anymore as I predict when the light will change and adjust my speed, I start to slow down a ways before I reach the light often times I'll be around 25 when it changes and I don't have to give the car as much fuel to get it going. Since I have adopted this strategy with my driving, My mileage as increased.

Answer 2

Best speed is around 53-55 MPH. The highway may have a MAXIMUM of 70 but you don't have to do it. Maximum means no higher than. Drivers can't seem to under stand that. If your wheels are questionable, or you are carrying a dangerous load, lose load or a large load you dont do 70.
Driving slower doesn't improve efficiency because the transmission has shifted down into a lower gear(which will use more gas to go the same distance than as if you went 55.(high gear) Keeping tire pressure up helps too.

Answer 3

The faster that you drive, the more gas you will use. You want to stay in top gear and as low a speed that you can for the best MPG. A lot of the time that is not practical, so try to get your car into top gear as soon as possible and then try to maintain a constant speed.

good luck.

Answer 4

Your car gets more economical the faster it goes up to a point (depending on the design of your car's bodywork) because the air resistance requires the engine to do more work to overcome. The air resistance increases exponantially with speed so after the point it starts negatively affecting fuel economy it increases alot with small increases in speed. Put your hand out of the window at 70mph and you will feel the force of air resistance the engine is having to work against to keep the car moving forward at that speed.

Answer 5

In stop and go traffic you waste mor e gas because you accelerate and decclerate, driving on the highway you use a constant amount of gas

Answer 6

For most cars, 55-60 mph is optimal for gas mileage. However, the average highway speed is much higher. For best gas mileage, avoid heavy acceleration and excessive starting and stopping.

Answer 7

lets say ur low on gas and u need to fill up and there is a gas station 5 miles away. U shoudnt go fast cause that takes mroe gas and power and if u go slow ur not pushing ur car and u will get farther. But in stop and og trafffic (TRAFFIC JAM) ur goin stoping.. going.. stopping, U waste some gas but not anything that is serious.

Answer 8

Fast uses more gas, since wind resistance is much higher. Your best fuel economy is the lowest speed you can do while in top gear. The ideal efficiency is to ahve your foot hard on the gas pedal at LOW speeds while in TOP gear (this increases volumetric efficiency.)

Answer 9

it is not plenty with the value you cruise at-that is greater "how briskly you pass to get to that velocity." gasoline utilization will enhance with call for (How a great way you push the throttle down). A motive force who gently eases as much as 65MPH from a lifeless supply up will use much less gasoline to realize this than a motive force who slams the pedal to the floor to get to the comparable velocity quicker. holding a tender cruising velocity is likewise stable for saving gasoline.. (The throttle being pushed as against being held stable for a volume of time). to quote an occasion-I as quickly as owned a 1970 Cadillac Coupe DeVille with a 472 cubic inch vast-block V8. with the aid of applying the above pronounced applying practices, i grew to become into able to force greater gasoline-effectively than i will in my contemporary smaller engined motor vehicle because of the fact such grew to become into the torque produced with the aid of the meant gasoline-guzzling V8-I slightly had to touch the throttle to get it-and shop it shifting. quickly or sluggish would not count. the way you get there DOES.
