Using LPG. Now there is a claim to fame anyone should be proud of! View: https://www.youtube.com/watch?v=5nH2nTuSCXQ
Using LPG is no big deal, its been used over here for years but the down side is, you will have a bloody great big gas tank some where in the back of the car, normally in the boot.
Why spoil a beautiful car by putting a huge great gas tank in the boot. is it really worth it? What next, A tow bar!!! Mike
The more modern trend for gas tanks now is to use a very thin tank mounted under the car or even in some cases a round flattish one one the spare wheel well. Ok, that means no spare but when was the last time you saw a Z on a space saver? Many cars don't have a spare these days just an aerosol blow up can and an electric 12v compressor. I think the resulting mpg gain would have to be very good to make it a worthwhile proposition as to cover the cost of fitting you would need to do a big mileage ( BMG take note ).
I'm sorry but I really cannot see the point of why someone would convert to LPG and stick that in the boot!! Madness
