the use of LPG could be of benefit for people operating fleets of vehicles such as Ian Page ("Life could be a gas", The Argus, February 12) but are private owners of LPG-fuelled cars or dual-fuelled cars with the option of petrol or LPG aware that should they decide to take their cars to France using the Channel Tunnel they will find they cannot?

Eurotunnel will not accept such cars. The poor record of botched conversions is the source of the ban but no exceptions are made for factory-produced cars.

Producers of diesel-powered cars claim the latest technology enables them to meet the emission rules in force and in some cases they are better than petrol engines.

As a result, statistics available indicate that around 25 per cent of new cars sold here are diesels.

The much-improved MPG rate being achieved seems to indicate that with the cost of converting cars to LPG it may be better to go for diesel.

If the Government would accept this and do away with the increased tax on diesel, the savings would be greater.
