Which uses more gas automatic or manual transmission?

Answer 1

It depends on how you drive it. If you are conservative on the acceleration, the Automatic will use more gas. If you like to run the motor hard, the Manual will.

Answer 2

well, depends on how you drive, automatic will shift at the appropriate time to save fuel, but if you manually shift it or hot rod it, then it will use more gas of course, the manual has to be shifted, so if you take longer to go into gear, ie more rpm's, then you will use more fuel, like if an auto goes from 2nd to 3rd at 2300 rpm, but you shift your manual from 2nd to 3rd at 3000, then of course the auto will use less gas. also going into the highest gear as soon as possible will save gas, but if you have a 3 speed or 4 speed, your highway driving will use much more gas than an auto with over drive, but if you have a 5 speed it will be about the same, but a 6 or 7 speed would most likely use less fuel as the highest gear can be selected to give less than a 1:1 ratio that an overdrive system usually runs at.

Answer 3

Gas mileage can vary for a lot of reasons. Maintenance and upkeep of an auto are really what affect its fuel performance. In the past it was believed that a manual transmission was better in the country and worse in the city. But performance is mostly affected by how often you do or don't change the oil and plugs,ect.

Answer 4

Automatic

Answer 5

Automatic transmissins use more gas. With manual you can shift when you want and it will not be going in and out of gears so much. If you check the stickers on new cars you will notice the difference between automatic and manual.

Answer 6

automatic, an automatic transmission has to be cooled, that heat is wasted energy. a manual transmission does not have any cooling. automatic transmission by their nature are always slipping (except when the tcc is engaged) A manual transmission is only slipping when the clutch is being engaged

Answer 7

Usually automatics because they require the engine to turn slightly higher rpm than manual transmissions.

Answer 8

Manual if used correctly gets better gas mileage and better acceleration.

Compare:
Honda Accord Auto 24 mpg city 34 mpg highway
Honda Accord Manual 26 mpg city 34 mpg highway

Toyota Camry Auto 24 mpg city 33 mpg highway
Toyota Camry Manual 24 mpg city 34 mpg highway

Mazda Tribute Auto 22 mpg city 26 mpg highway
Mazda Tribute Manual 24 mpg city 29 mpg highway

If used incorrectly it could use more gas though.

Answer 9

Generally an automatic would use more fuel because of around 5% slippage at the torque converter as it is a fluid drive.

In modern vehicles with computerised transmissions this problem is eliminated through torque converter lock up in economy mode/OD on. So there is nothing in it on newer cars unless you are constantly in power mode/OD off.

PCM's also combine engine and trans management for even further economies.

Answer 10

I would say the automatic I own a V-6 Ford and have a lead foot, keep maintenance up as well, change that fuel filter, no cheap gas, at least I stick with Shell, BP, ect..
