helo PW , today i calculate the fuel consuption of my 07 CUltus VXR ,,,,,,,,,,this car is on my brother's daily use,,,,,,,,,,,,,its completelly stock,,,,,,,,,,no alteration no modification,,,,,,,,,,mentainance totally done by me from day one and no one has even open its bonnet other than me ,,,,,,,,,,,,carb is totally untouch never been open,,,,,,,,,,,,and till now engine is in sound condition ,,,,,,,,,,compression pressure is all ok,,,,,,,,,,,,no sigh of any oil consuption,,,,,,,,,,,leak piston rings , valves , quides , valve seals , head gas kit , its been driven on havoline 20w-50 since day one ,,,,,,till now it easily touches 120km on CNG but these days i am using it only on petol,,,,,,,,,,,but all that doent mean that car wont need any further mentaince and mechnically its in tip top condition ,,,,,,,,,,,,,,yes it need to replace timing belt , plugs , plug leads , distributer cap and rotor and ofcourse carb need cleaning and acording to my experence its running rich,,,,,,,,,and also ignition timing which is not spot on ,,,,,,,,,,,
and yes tires are also not stock and not balanced and last night i forget to mentain the air pressure and i am sure all these things effect on fuel consuption ,,,,,,,,,,,,
another thing i must say is that there will be some air pockets left inside the fuel tank even if you fully toped it just as i did,,,,,,,,the more acurate reading can be find if you attach an auxiliary fuel pumps and a seperate fuel cell or bottel ,,,,,,,,,but all that is not safe and need some precautions,,,,,,,,,,one i have done that on mehran and i got 19Km/L with in city,,,,,,,,but its carb was not stock,,,,,,,,,,,i have change its main fuel jets,,,,,,,,,,you can do that on mehran because it has a mechnical fuel pump attach near distributer ,,,,,,,,,,and here in my case i need to buy a electric fuel pump just for this purpose and wire it up,,,,,,,,all that need lot of time ,,,,,,
ok so thats a littel intro of this on ,,,,,,,,,,,i fill the tank to its mouth,,,,,,,,,,,,and use it next day on my daily routine ,,,,,,,,,,,travelled 36.5km and refil the tank again with measuring flask,,,,,,,,,,it add 3.4L before it topup exzactelly at the same level,,,,,,,,car driven between twin cities,,,,,16Km with 2 passangers and 16 Km with 4,,,,,,,,,,i got around 10.7 Km/Litter on this car ,,,,,,,,, condition of this car is as above mentioned ,,,,,,,,,engine is demanding for some tuning as you know till now nothing has been done on this car ,,,,,,,,i remember one i service it distributer and thats the first and last mentaince till now ,,,,,,,,,,,,,hopefully will find some time soon and tune it so that i can add some more km/L ,,,,,,,,,,
