My 3.6 litre jagaur can in terms of pernce per mile in fuel. it returns 22.8
MPG on gas (LPG) which cost half the price of diesel or petrol over here so
it costs the same as a car returning 45.6 MPG. Last time it was tested the
gas anlyser showed zero HC and zero CO. there are other diferencece in a
jagaur sovergin and a jetta 1.9 TDi.. but I dounbt it beats the sov on much
other than ease of parking.. So why would I want a desel?

Cant remove the biggest problem with deisels, the particualtes.. whcihe I
mentioned earlier, these are not gas but soot, which will block up the
catastrophic converter.. On little known fact they don't want you to know
abiut these things, they are a total con. the production of a each cat

LPG is a waste product of the refining prosess of either fuel

menwhile gas is being ignored. and as methane is produced by rotting
anything although you may think it smells a bit bad pure methane does not.
Any LPG car will run on it and its fairly renewable (as long as there is
somthing to rot). and it produces 0 enisions.. water and CO2 and thats it
and without any fancy emision control gear. (the very prodution of which is
poluting)
