Hello all. I got corolla 05 model, after 6mnth of normal d car start consuming fuel like anytin. I ve chang d plug, clean d fuel pump, chang d gear oil. 4d oil d mecha uses ATF Dextron 111 instd of 1v. Honestly dis car still drink fuel. Any advise

Run a scan first. There are too many components on a car responsible for high fuel consumption. Only a scan and test can reveal which of them is bad. If yoy are in lagos and you need a solution. Call multi autolab on 08165520837 or 08156087872. Free scan for you ends by 5pm 20th june 2016

I got d car scanned ystd at abj, no error was detected. D check engine does nt indicate on dashboard

We see invisible check engine lights these days with numerous faults stored on the ecu. What type of scan tool was used?

Do u knw any where i can get the car scan again in Abuja

Your car won't drink fuel excessively without some black smoke coming from the exhaust. Pay attention to the quality of fuel you are buying, driving habits and transmission shift quality.

However, abnormal things that can make a car thirstier than normal are:

01) Dirty / clogged air filter.
02) Incorrect ignition timing. *
03) Under-inflated tyres (higher rolling resistance).
04) Binding brakes.
05) Leaking fuel injectors.
06) Blowing exhaust system.
07) Faulty MAF (mass air flow meter).*
08) Faulty CTS (coolant temperature switch).*
08) Faulty o2 sensor (Lambda).*
09) Thermostat stuck open, or removed by some dodgy mechanic. Over cooled engine.
10) Split / perished vacuum hoses, engine drawing in unmetered air.*

I would suggest an OBD scan. All the items marked with an asterisk will normally trigger an engine check light (CEL). It would help too, if you can recall when you noticed the higher than normal fuel consumption. Did it occur after any work was carried out on the car? The thermostat is an area I would look into - if it's stuck open (or it's been removed) the engine will never reach its optimum operating temperature. The CTS will sense the engine is not hot, and the ECU will send more fuel through the injectors as a result. This is done by altering the duty cycle (the amount of time the injectors are held open will be longer).

Tyre pressures are also important, if the pressures are too low, the rolling resistance will place more load on the transmission, then the engine will work harder. The same goes for brakes that are binding (sticking on).

Thks all, i think i ll change d gear oil 2 ATf 1V as recomendd n i ll get d car scan again bf i do any further damage
