If you've got an old cast steel engine you should really LPG it anyway. You'll save about 50% in fuel costs so it'll pay for itself in no time. You're charge free then, as you well knowKeyboardJockey said:However if you convert your 4x4 to alternative fuels like natural gas you won't pay the charge anyway.
Pisses me off it does. I drive a 4x4 cos I need one for trundling back and forth from the allottment with tools etc. I'm going to be hit by a charge that is aimed at wankers who use a 4.5 litre jeep for going half a mile to the shops and clock up 30 odd k per year whereas my motor is 2.25 litre and only does 3k miles per year. I'm going to be penalised for driving frugally and sensibly just because I drive a 27 year old classic land rover.

Modern engines have a much lower benefit from LPG because they've been engineered up the wazoo to deal with the muck we call petroleum spirit.
