High Petrol Consumsion

[sanlen]

Hi All,

I am using Toyota Camry 1998, Canada made. I pumped 20L of petrol and started to measure how far i can go. With that 20L of petrol i can only drive for 72Miles (in the city with not busy trafic)

I feel it consume more petrol than usual, and more than other cars (same branch)

Could you please advice what are the posible problems? Could it be the spark plug, and something else?

Thanks

you have to measure it more accurately. fill up the gas tank at gas station that gives you exact number (amount) of liters/gallons poured into tank (Shell does it).
reset your trip meter at fill up. the next time you re-fill the gas tank just divide the driven kilometers/miles (before resetting it) by top up liters/gallons from the new receipt. it will give you exact MPG number if you convert the numbers right. metric mileage measure is used liters by 100km. in USA we use driven miles per 1 gallon.

72 miles per 20L sounds horrible, it makes around 13.64 MPG - that is totally not right. with 4 cylinder engine you should be getting around 22 MPG in city and up to ~32 MPG on highways (with light accelerations).

based on 20 L = 5.28344 gal(US Liq).

well, if there is no Check Engine Light on (no error codes) then i would start with a minor tune up:
-new Toyota/OEM/Denso/NGK spark plugs (stick to double platinum or Iridium, stay away from cheap "standard" models)
-new NGK TE58 spark plug wires (assuming you have 4cylinder 2.2L engine)
-new air filter
-new fuel filter (Toyota/OEM/Denso or WIX recommended)
-new PCV valve and grommet from the dealer
-new fuel cap for gas tank (from dealer only)

also you can check front brakes for dragging, if after driving one of wheels gets very hot then you have the problem.

how many miles on car ? when were the accessory belts (alternator, power steering) replaced ? any leaks ?

there is tons of things that can impact the MPG, simply not enough info to point you in the right direction.

Hi,

Thank you very much for the advice. i took my car to check up, and they said there is no problems with my car. Everything seem to be ok.

I am thinking to change the air and fuel filter. Could you please advice what is the mail responsibility of this air and fuel filter? They are part of petrol comsumption? My car is around 90000 miles now.

Thanks
