Despite advances in fuel injection, engine management and the increasing usage of more sophisticated engine design etc in the last 20 or 25 years or so (ish), modern cars (and for purposes of this comment I'm considering 20 year old Hondas as being relatively 'modern') tend not to have significantly superior economy to much older cars of similarish size and engine capacity. This is because modern cars are fat and heavy compared to equivalent but much older cars (all that AC, PS, CC, sound systems, extra sound deadening etc...).

i agree on the comment about the honda's design are modern.. It seems like honda's technology is way advance compare to other manufactureres out there.. not just in engine technology.. overall

I remember my moms 1983 accord, power steering, electric sunroof, and its a hondamatic 3 speed ahaha


especially Vtec engine are very fuel efficient compare to other 4 cyl engine out there.. no matter in the 1.5, 1.6, 1.8ltr and up.. its has more % efficient if you compare to other engines..'

And i believe if you run LPG in the car you get less power.. thats what mate said who own a falcon 4 ltr. IF his in LPG mode even his foot on the floor it doesnt giv you the power the way petrol givs it to ya.

And he said.. If your travelling in LPG and you want power just swittch the switch to petrol and it feels like its a NOS.. lol :)

The difference would be less pronounced if the conversion were to LPG only (i.e. not 'dual fuel') and all measures taken to optimise the engine to use LPG most efficiently. Problem is that if optimised for LPG, petrol will destroy the engine...
