Hello i have recently purchased 2003 corolla X with import of year 2006.
Car is on duel fuel (Petrol /CNG) with awesome milage of 230km / CNG tank. Yesterday i have tested it on motorway for petrol mileage and the result seems to be awesome as well.
I filled tank in G 11 PSO petrol pump, with average speed of 100km on motorway. At Charsadda i filled again to check the consumption and it consumed 7.6 liter for around 140 KM.
When i did calculation the average was 20. km/ltr.
P.S. My car has knocking issue and we had 4 passengers seated with lots of luggage with us.
Thoughts??????
