Need Help santro Exec high fuel consumption

[pwuser147938613457]

Dear friends, I was recently facing high RPM problem . I changed the throttle body, fuel pump, plugs, air filter , oil .Although the RPM has become normal now, but still the fuel consumption is very very high. My santro is giving 4-5 km per liter on petrol and 80 KM full tank on CNG. Both without AC. Pls help me or suggest a good mechanic

Salaam . brother my santro executive is consuming lot of petro. I just got all the plugs changed, fuel pump changed, rpm sensor changed. But still the issue has not been resolved. Its giving me an average of 5 kilometer max per liter. I've also checked but didn't find any leakage. Any help??

I had a similar problem and was able to jump the mileage from 7 to 11 (more experiments in progress)

1. Tested different fuel pumps - the local PSO was shit, moved to Attock.
2. Tested different fuel types - mixed Hi octane and local - significant jump of about 1.5 km / ltr
3. By far the most was due to my driving speed - previously I used to try to move as fast as possible and then put car into neutral and cruise to stops, speed breakers etc in Isb this was usually 80 - 100 kms / hr. Now I stay below 70 all times.
4. One trick is to keep engine RPM as low as possible judging by the noise, as soon as it goes high I simply shift gears.

The entire process took a good 3 months so be patient!

Hope this helps and do let us know the results.

Hey, i am also facing the same issue. Just recently, I filled up my tank with 20 liters of petrol and it gave me 307 km, I ran my car till the fuel tank ran empty, i again filled my tank up this time 30 liters but it consumed petrol a lot not to my expectation, and at 150 km the tank was nearing empty, I called my mechanic and he said it requires tuning. I will get it done tomorrow and will let you know.

Try checking your clutch plates. If there is a problem in clutch plates, it can cause a drop of 40-50% of fuel consumption.
