Thats called physics. the gauge (economy) is designed to give you a visual reference as you accelerate so you can monitor the fuel consumption rate.

How to save fuel and make your vehicle last longer, too


Improving fuel economy is easy - just take it easy. It willmake your vehicle last longer, too. Here are some specific tips on how to savemoney on both fuel and repairs.
  • Keep your tires inflated at the correct pressure. Under-inflation causes tire wear and wastes fuel.
  • Do not carry unneeded weight in your vehicle. Excess weight puts a heavier load on the engine, causing greater fuel consumption.
  • Avoid lengthy warm-up idling. Once the engine is running smoothly, begin driving - but gently. Remember, however, that on cold winder days this may take a little longer.
  • Keep automatic transmission selector lever into "D" when engine breaking is not required. Driver with the selector lever in "4" will reduce the fuel economy. (This is referring to vehicles with Automatic drive)
  • Accelerate slowly and smoothly. Avoid jackrabbit starts. Get into the high gear as quickly as possible.
  • Avoid long engine idling. If your have a long wait and you are not in traffic, it is better to turn off the engine and start again later.
  • Avoid engine lugging or over-reversing. Use a gear position suitable for the road on which you are traveling.
  • Avoid continuous speeding up and slowing down. Stop-and-go driving wastes fuel.
  • Avoid unnecessary stopping and braking. Maintain a steady pace. Try to time the traffic signals so you only need to stop as little as possible or take advantage of through streets to avoid traffic lights. Keep a proper distance from other vehicle to avoid sudden breaking. This will also reduce wear on your breaks.
  • Avoid heaving traffic or traffic jams whenever possible.
  • Do not rest your foot on the clutch or break pedal. This causes premature wear, overheating and poor fuel economy.
  • Maintain a moderate speed on high ways. The faster you drive, the greater the fuel consumption. By reducing your speed, you will cut down on fuel consumption.
  • Keep the front wheels in proper alignment. Avoid hitting the curb and slow on rough roads. Improper alignment not only causes faster tire wear, but also puts an extra load on the engine, which, in turn, wastes fuel.
  • Keep the bottom of your vehicle free from mud, etc. This not only lessens weight but also helps prevent corrosion.
  • Keep your vehicle tuned-up and in top shape. A dirty air cleaner, carburetor out of adjustment, improper valve clearance, dirty plugs, dirty oil and grease, breaks not adjusted, etc. all lower engine performance and contribute to poor fuel economy. For longer life of all parts and lower operating costs, keep all maintenance work on schedule, and if you often drive under severe conditions, see that your vehicle receives more frequent maintenance.
Good luck.

It drinks too much in the city. Way too much. What can I do to change this?


If a tune up hasn't been done in a while, it certainly would help to have fresh spark plugs and fuel filter as well as air filter and oil change. Keeping the tires properly inflated will reduce unnecessary fuel consumption, and turn the ac off when you're stopped and accelerating then turn it on when youre cruising at speed.

I have 4A-FE Motor but if i run the air conditioning RPM counter down to 0.8 ???


the power drain with a/c is about 25% so you would expect a drop in revs at tickover,but the engine electronics will keep tickover to about 800 to 1000 depending on ambient/start temp. nothing to worry about.
if you had a 4ltr engine the drop would be next to nothing......but the fuel consumption.........

Fuel-consumption


Drive slower and easier. about 1 or 2 BELOW THE SPEED LIMIT DON'T PASS ANYONE . When you accelerate accelerate nice and easy watch the tachometer try to keep it below 3000 rpm all the way up to your cruise speed nice and easy don't worry about the guy behind you . Brake easy if you are coming to a light take your foot off and coast and try to time the light so its green when you get there. then EASY EASY on the gas keep it under 3000 RPMS all the time you are accelerating.
No special oil no special spark plugs or fancy air filters just factory parts whren you tune up every 3 or 4 years and change your oil about every 3 or 4 years yes 3 or 4 years it wont hurt it a bit just remember to always check the oil and add if it gets 1/2 Qt low. change the fuel filter EVERY EVERY 15,000 MILES fuel injection professional pressure cleaning once a year Air filter when it is dirty, please dont believe all those gimicks out there I have a car we change the oil about every 4 years and it has 350,000 miles no engine work yet runs every day passes emsssions every year no repairs needed fuel filters once a year or 15,000 miles
