Potential buyers are often frightened by LPG – but a good, professional installation is nothing to worry about. A few extra holes are drilled for the tank, regulator and so on, but the gas filler nozzle (often set into the rear wing) can be mounted on a discreet bracket under the car for painless removal before resale.
LPG’s a viable proposition if you cover a high mileage. It produces less power than petrol, but the engine runs more cleanly, which means less carbon build-up and better emissions. Do your sums carefully though. If you cover 5000 miles per year in a car that returns 25mpg, you’ll save around £300 by running on gas rather than petrol at current fuel prices. It’ll therefore take you a very long time to recoup the £2000-or-so it’ll cost to get the car converted.
Only use an installer that’s approved by UKLPG (see www.uklpg.org for a list). You’ll need to declare the conversion to your insurer – and this is likely to require a UKLPG certificate to show that that the job’s been properly done.
LPG works best on high compression engines.
