Mehran 2011 Fuel Consumption

[pwuser150649237912]

Dear All - I have 2011 Mehran, giving average 8km per liter on Patrol in city and 10km on long route with AC but a year ago i checked it gave 15km per liter, further even i tried on CNG it gave 60km in a cylinder within but in past it gave minimum 90km within city and 120km on long route. I get tuned from local mechanic and even Suzuki showroom but still no improvement. Would you please suggest what should i do now?
Moreover i read topic to change fuel jet with larger size improves mileage, is it true? here is article link

That,s how to maintain the fuel average of Mehran(petrol Carby)

AoA brothers I am sharing the simple procedure how to tackle with it I am sharing the mileage of my Mehran and the 2 others belonged to my cousins and uncle which i have maintained. I have 2010 Mehran with 155/70/r12 tyres and alloy rims and its average on Long is 20km/litre and in city around 17-18 Km/litre. My uncle have 2007 mehran with 13 inches wider tyres qabli wale and japanese rims and after its setting giving 18 km/L on long and in city 15-16 km/L My cousin have 2011 Yello cab scheme me…

no it dosent use smaller jets and change spark plugs and fuel filter your milage will surely increase

is fan on auto and also does thermostat valve installed

Maybe there is a leakage in your fuel lines or the fuel rubber lines in engine area and near tank have become hard. Just to confirm check your car mileage by using 1 ltr bottle direclty connected safely with the carburettor. if the mileage imporves it means u have a leakage in your system.

do not hang or put the fuel inside engine room while checking the fuel avergae.

Yes FAN is auto but what is thermostat connection with consumption? if FAN is auto which reduces heath but installing thermostat valve FAN will ON on fixed temprature.

[babaralinawab]

thermostat is removed or is always open engine will not heat upto optimum so it will consume more fuel

Ok I will try today but will use bottle.

[nnabeel]

yes use any 1 or 1.5 litre bottle but please do not hang the bottle inside engine room while testing. keep it handy or fit some safe place to avoid any fire incident.

one of my friend did it in engine room and got his car engine room fired up due to loose connections.

Ok Noted, Thanks!

Mr. Nabeel - By the way if leakage is the issue why it's mileage low on CNG as in past mileage in cylinder was 90 but now 60. Do you still think leakage is the issue or ?

Did Bridgestone tyres size 155/70 is feasible for Mehran VXR 2011 or not.
