Toyota Vitz fuel economy

[ahmedfarhanrk]

I have vitz spider shape. When i bought it, it used to give me fuel average between 12.2-12.5km/l but after sometime it was 11.5km/l. I have also done its general tuning and now it is showing 11.6km/l. Mechanic has said that my car engine is also working perfectly. I am using liquimoli engine oil 10w40 and my car has driven almost near to 71000 km. I have heard that vitz gives 14-16km/l within the city. What can be the reason for low fuel average?

Shift the engine oil to 0w20 and then test it again

✓10w40 is not correct. Use 0w20, or maximum 5w30.
✓Tyre pressure must be 36 front 34 rear.
✓Vitz fuel average mostly depend upon driving style. While driving, you must ensure not to rev higher. You must be in eco mode most of the time, and try not to go beyond eco for long.
✓Clean the throttle body and MAF sensor.
✓use genuine airfilter
✓Use spark plugs DENSO SK16HR11.
✓You must calculate the fuel average by tank full method 3 times and then take arthemetic mean.

With these measures, you will get maximum 14kmpl. More than 14 is just a dream. Trust me.. Some people say 18-22, all lies.

BTW whats the tyre size you are using?

dont ever clean throttle and MAP or MAF sensor until and unless you want to mess things up

Ok sir

Why is it so ? Normally I think every mechanic suggest throttle cleaning after 10k kms ?
