Question about 1992 Toyota Camry V6

1 Answer

High gas Consumption

I have a 1992 Camry and i have a friend who has exacly the same model. I used my friend's car for about 2 weeks before getting mine and was impressed by the gas mileage, but was disappointed that my own Camry gave me far less than what my friend's car did.

One thing I noticed though, in mine, is that there is always a sound like an air leakage from a suction pump coming from the hood whenever the engine is running, and it increases with acceleration. I checked to see what it was and it appears to be coming from a cracked air intake hose connecting the air filter and the injector. could this be the cause of the high gas consumption, or does the car have compression problem too? What else could be the cause and what is the solution?

Thanks,

D1

Most definitly that leak is leaning out the motor so the oxy sensor thinks therse not enough fuel and tells the injectors to put more fuel in.All parts of the air box must be leak free.The air filter should be clean and the lid securely fastened.A compression test would tell you the health of the cylinders and wether theyre working efficiently.The lower the compression ratio the less effectivly the fuel is burnt.If you have around 140-150 your engine is in a reasonable condition.

High fuel consumption in toyota camry 2002


make sure nobody is stealing you gas, check for leaks, keep you foot off the gas pedal, turn off your air conditioning whenever possible. Don't speed. Otherwise, new plugs and a tune up may help.

1973 ford f100 seems to be going thru so much gas, just using for around neighborhood, but have used $30 worth of gas in a week


Abnormally high fuel consumption is usually an cry for a tune-up, the normal, plugs, points, condenser, set timing, change oil and filter, air filter and adjust carb with any one of several tuning systems in use. Then if you wish, go on to things like wheel alignment, brake adjustment, universal joints, wheel bearings, tyre pressures, - these are all things that would contribute to increased fuel consumption.

How big is the gas tank on a 1992 ford crown vic. how many miles to the gallon. my gas gauge doesnt work. so i dont know anything about the gas.


1992 Ford Crown Vic 4.6 L V8 Automatic

Fuel tank capacity is 20 gallons (US).

Your fuel consumption will be affected by many factors, such as :
- how you drive the vehicle
- the condition and tune of the motor
- driving conditions (traffic, city use, highway use etc)
- tire pressures
- type and grade of fuel used .

It is impossible for me to estimate what fuel consumption you can expect from your own particular car without a whole lot of information.

It's unwise to run the vehicle for long with no working fuel gauge.

If the tail smoke is blueish (not dark and sooty) and the engine runs right then it's a leak. Put the car on a clean flat surface, start the engine and look for the leak - start with the fuel tank.

How to improve the fuel efficiency?


my 2 cents -

1. You didn't specify your exact model, on this site you'll fond your answer - http://www.fueleconomy.gov/feg/bymodel/1989_Toyota_Camry.shtml

2. There are a few ways to do this, here's one -
- Fill your gas tank to the very top.
- Write down your odometer or reset you trip meter.
- Drive your car till it's time to fill it up again.
- When it's time to fill you tank, fill it to the very top (preferd in the same station, in the same pump).
- divide the number of miles (or kilometers) you drive, by the amount of gas you filled, This is of course only true for this gas tank, fuel consumption is effected by many things, load, driver, type of miles you do (city or hoghway), etc..

3. Service your car regularly, make sure tire pressure is correct, don't drive like you are racing.

Good luck,
Eitan.
