What is the best way to improve MPG on your vehicle.?

Question

I have read many tips about improving MPG. What have people personally found to work the best?

Answer 1

the slower the speed, the greater the mpg!!!

Answer 2

Maintain good tire treads and air pressure.

Answer 3

there's an optimum speed for your vehicle for getting best MPG.  a lot of cars sold in the US have this set around 55, sometimes just a bit lower.  if you drive faster (or slower) than this you'll experience a faster rate of fuel consumption.  if you have a sports car you may have a higher point for best mileage.  if you have a manual transmission, you can change your highest gear to allow a faster optimal speed, i know someone who swapped out just 5th gear on his 5-speed manual for one that allowed best mpg at 67mph.  that's expensive but if you have a very long highway commute might be worth it.

stepping on the accelerator not too fast, yes, that helps.  but too slow and you spend too much time at lower speed than optimal and in lower gear, which also wastes fuel.

i've found better MPG with premium fuel or octane booster, but not usually enough to make up for the added cost.  but, if it's on sale for the same price as regular -- sometimes a station will do that one day a week -- then get the premium

if your car has a turbo, you want to keep the rpm of the engine below the point at which the turbo engages, to save fuel.  however, this may result in increased carbon buildup inside the turbo.

disconnecting your exhaust (illegal generally) or buying a low resistance racing exhaust (legal but maybe expensive) gives you better performance and better MPG, at the cost of a lot of noise, since the resistance going through the exhaust increases the load on the engine.

i've gotten up to 40 mpg in my old corsica, a gasoline engine, driving about 47-48 mph which seemed to be optimal for that car, but only on long highway trips.  in my diesel beetle, i could get over 50 mpg fairly regularly, which is why i got a diesel.  now of course diesel is much more expensive than gasoline, but when i bought the car it was just the opposite.  you can buy and use biodiesel for less than gasoline in some areas, also if you get a diesel, you can get a conversion kit which allows you to burn straight vegetable oil, something i always wanted to try, but it's around $800-$1500 for a kit.

frequent oil changes, you get slightly better mpg with lower viscosity and/or synthetic oil, but it can cost quite a bit more, and is more likely to leak.

so many other things.  but the easiest is just don't be impatient, put on some nice soothing music, and drive within the speed limit, you'll get much better mpg if you stay around 55.

mmm, almost forgot, tire alignment and balancing is important too.  tires out of alignment and/or with unequal wear cause increased resistance which translates to more fuel consumption.  rotate your tires regularly.  all of this, if you're paying someone to do it, may not be worth what you pay for it added fuel economy.  repairs and mechanics are expensive.  learn to rotate your own tires, it's not that hard.

or, you could just cut a hole in the bottom and do a fred flinstone ;)

Answer 4

good tune up  and tire air pressure  and avoid hard starting and stopping

Answer 5

30 percent of milage is driving habbit that and frequent tune ups

Answer 6

Driving more gently will make a huge difference. Whenever you can, keep the RPM's at or around 2000 when accelerating. Also, try to time traffic lights so that you don't have to come to a complete stop. That way, you don't have to spend as much time accelerating. Using the cruise control when possible and driving slower also help.
