@sinbad. well u got my calculation right. not sure abt cng calculation. overall diesel is better than CNG. CNG has one positive that is cheap fuel. rest all disadvantages.
to sum it up
- fuels is cheap
-Extra price for kit, insdtalation etc
-heavy cylinder so suspension ruined, tyres ruined
-longer ques=waste of time. there are few pumps in isloo i pass evey morning at 9am there are at least 50 cars in que. i asked a friend he said that the pump has higher meth value so better cng mileage.
-engine wear is greater on cng as more pressure is put on it due to lower power of fuel
overall cng sucks big time.
oh and the averages i put up for both my diesel vehicles is for RWP ISLOO inter city trips.
RWP LHR is did go via motorway but didnt calculate. i think it ate 45 litres of diesel. not sure. some 1 tell me theri motorway avg please...
now i m gonna buy 3 door prado with 1kz-te engine (turbo) should give me 10mk per ltr but awesome power.
