I had a TK Bedford with the 214 cubic inch petrol six for a few years in the '90s. Used to do around 10 mpg. It had a dual fuel setup when I got it and I ran it on LPG all the time because price wise I'd have been crazy not to. Can't see the point doing a conversion on a little car that doesn't hog the juice much anyway but for the truck it was great. Only drawbacks I can see with a car are fuel availability, which used to be good here in New Zealand but is now not so good, and the question of where to mount the tank. I'd be inclined to go LPG dedicated if the conversion wasn't outrageously expensive and fuel availability wasn't likely to become a problem because I don't believe it is possible to set up an engine to run sweet on both petrol and LPG. No matter what you do it's likely to run sweet on one and like a bag of dicks on the other. The few times I ran my truck on super petrol just to see if it would it was terrible. I have an idea that the ignition may have been advanced too far for 95 octane but it seemed just right for LPG. Anyone care to comment on that theory?

Advance curve is different for lpg, more sooner but less overall as a guide. I would guess the old Bedford had had a mega head skim to up the compression to get the best out of it on gas or had a restriction caused by the mixer making it run very rich on petrol. Lpg injection systems pretty much mean they will run almost as well on both fuels when set correctly, if you ran a programmable ECU like mega squirt with a switchable different map for each fuel and kept compression ratios sensible you should be able to get the best out of each fuel. I got behind a guy in Aus once putting 600l into a little international truck powered by a V8. Makes my 140l fill look small.... It's there any availability of CNG anymore? I remember them removing the pump from our local place when we were in Auckland.

The old Can Not Go? Haven't seen that in years, probably decades even. Don't think it was ever available in the South Island.

Certainly wasn't available by the late 90s on the South Island if it ever was. We nearly bought a CF with CNG but I couldn't get my head around the separate gas warrant, then he said the only places he could get it were pretty much Auckland and Wellington.. I did horrify one guy telling him how to run his lpg van from an upside down BBQ bottle, it was a small town with no car gas pump but the local station did BBQ bottle refills...
