I always hear talk about people with manual transmissions save more gas than people with automatic cars. I have the old school manual. Not this new stuff where there is no clutch. I have a clutch on mine the old school stick shift. Anyway, I've been trying to save gas. Do I burn more gas in a higher gear or a lower gear. Where should I keep the RPM's when I'm driving in the higher or lower gear at that as well? Example. It redlines at 9000 RPMS. I'm trying to save gas. Should I have it halfway driving in that particular gear, and should I be driving in a high or low gear so I don't burn as much gas?

HIgher, lower gears use more RPM's making the engine work harder.

The lower the rpms the less gas it is burning, so you are better off in a higher gear. HOWEVER, not too high because that puts a strain on your engine, any savings on gas would be more than eaten up by blowing your engine out. By not having an automatic transmission to run you are saving energy right there. It is against the law to take your car out of gear and coast downhill or coast to a stopsign or stoplight, it subtracts from your ability to control the car.

To be truthful, the amount of gas you save depends on how hard the engine is working. If you drive uphill it will take longer for you do get momentum and the engin burns more gas in pushing you forward. if the engine doesn't transfer any energy into momentum then the engine will work more efficiently. If you drive seventy miles an hour in top gear you are not working the engine, but just maintaining the workload. If you drive fast in a low gear, you are only going to damage the engine and transmission because of the heat and friction building up in the transmission. Auto-matic engines use a pre-determined amount of fuel to drive in each gear. It may effect the miles on a tank-full but not the fuel-efficiency. A specific car engine is going to burn the same amount of fuel over an hour no matter how far you go. The car makers just let a car run until it runs out of gas. They use the hours it ran, average 60 miles per hour and then do math to get how mailes miles per gallon you will get. If a car runs for 4 hours and then quits, and it has a 10 gallon tank and you assume you went 60 miles each hour (240 miles) and divide that by 10 (24 miles to the gallon) then that is the optimal range - give or take 4 or 5 miles to the gallon. When you turn a car on and off, the fuel used to prime the engine gets burned faster and the fuel in the engine may evaporate (wasting some fuel), in stop and go traffic, your car will be on for the same amount of time on a tank, but the miles per gallon are going to depend on slowing and stopping and turning the engine on and off. My Saturn is an automatic, when I drive in the city I get about 290 miles to the tankfull (11 gallon tank), when I drive non-stop through NC I get 410 miles to the tank-full. I all depends on how you drive.

Accelerate briskly to about 4000 RPM and shift to the next gear. You get the best mileage in the highest gear at the lowest RPM. On a five speed fifth gear is usually overdrive and allows you to operate the car at about 2000 RPM.

Drive in a higher gear. The lower the RPMs the better. When I'm on the highway, I'm always in 5th gear. I'll even put it into 5th while driving in town.

Best gas mileage is obtained in the highest gear that the car will run smoothly at and the lowest RPM.
Example 45mph 1500 RPM 5th gear
Optimum performance and optimum gas mileage are opposites.
Take of slowly, get into high gear quickly cruise below speed limit.

Manual transmission - most effective gas saving measure is predicting red lights, stop and go traffic and go into neutral thus coasting and rolling - as free as you CAN get. Rpm's defiantly play a role in fuel consumption. RPM - stands for Revolution Per Minute right? I need fuel to produce a revolution - thee fore the less RPM' the less fuel.

Higher gear is more efficient. I noticed a drop in my gas consumption after I made an effort to coast a lot more with my clutch all the way in.

allways remember that the higher gear you are on you consume more gas as more power is required. if you are on the 4th gear which is the last gear, you burn less gas. ideal speed in City is 60 KMPH and highway is 120 KMPH. to save gas. do not keep your clutch pressed continuoesly as it will spoil your clutch plates. release it after you have changed your gear.

gasoline or Diesel? It seems such as you have gotten a tachometer precise? 4th. kit and 40K no longer stable! a million; whilst utilising you may desire to maintain "a minimum of" thrice the idle velocity to maintain from over stressing the Engine and Transmission. 2; protecting the RPMs up (in all fairness) maintains oil stress, lessens stress on the Engine and Transmission. 3; On gasoline engines the wear and tear by using the years isn't so glaring different than after a time that "no count the RPMs you at the instant cannot maintain velocity on the slightest hill "Bridge". 4; Diesels are much greater serious and with a rapid, with low oil stress you may desire to lose the rapid! Black smoke from a Diesel is "gasoline" counting on your engine and max RPMs (purple-line) 2,2 hundred to 2,500 RPM is a robust spot. Does shop gasoline and enables each thing to final longer. final question; "what value greater, gasoline or a clean Engine?"
