Its all about money
Cng give a little more milege than petrol
Cng give less power than petrol
12kmpl on petrol yes
13kmpkg may be yes might give more
12 in 115 pkr
13 in 65 pkr
Hmmm
Full tank cost 115 per ltr
40ltr =4600
40?12=480
Distance 480 km per tank with power and speedy fun
Full cylinder cost 66 per kg
7 kg =462
7?13=91
91 per cylinder
455 km in cng cost 2310
480 km on petrol cost 4600
4600-2310=2290 pkr difference
cng will require 4 to 5 stops and car will be underpower and with ac not even good on other hand petrol will require one stop and keeps car strong and powerful
those who travel 500 km in 10 days
saves 6870 in 30 days
Little more than 82440 in one year
so who cares if car engine gets dull and crap
hope these statis help you guys
