Dual fuel. You'd need to get rid of petriol.
Stop paying tax and SORN it. Then buy one of those things Bae invented that make tanks look like Range Rovers. Make it look like a pushbike and your sorted. You should be able to get the kit and software for 20 or 30 million.
My range is LPG and I get a discount on my tax though?
...if I register my RRC as an LPG vehicle? Bascially, it's still got petrol tank and starts on petrol, but has an LPG tank too. Would this qualify for cheaper car tax and/or free entry to the London Congestion Charge zone?
Cheers!
I think if its on the log book as duel fuel it gets exempt from the congestion charge look at TFL web site thats transport for london.
