When you are going say 60 and you are in w/e gear doing 4-5k rpm... thats when you kill gas millage and put extra strain on your engine. Toss it into a higher gear and drop the RPM's down to say 1500-2000 and cruise, that will keep your gas millage up and wont hurt anything. 1 gear higher than what you normally would drive in at a given speed is the best way to go about it.
Just remember that gears get lower ratios as they go till 4th (1:1) and 5th (0.XX:1) The less RPMs with a higher top speed usually helps you out.
Also, if you have the little radio display thing that you are reading your gas millage from, it averages it out based on speeds. So if you are constantly speeding up and slowing down like in city traffic your gas millage is going to go to shit. if you drive 200 miles at highway speeds with your car in a higher gear doing less RPMs, your millage will always gain.
Other than that there isnt much more you can do for gas millage, aside from switching out rear end gears. |
