| Thank you for your email to MINI Customer Information.
We can confirm that MINI do not recommend and therefore do not offer conversions of our vehicles to run on LPG. This is for a number of reasons, as listed below:
• MINI petrol engines are designed for petrol fuel (liquid fuel). The use of other fuels requires massive modifications to maintain MINI standards
• At high engine loads using gas it is possible that thermal damage will occur around the valves since gas does not offer a lubrication effect. Petrol contains additives for this purpose
• MINI have reservations relating to the thermal stresses placed on exhaust components. Such high temperatures occur when gas is used as a fuel and the engine is working at full capacity that the catalytic converter may be damaged and as a result the engine will be unable to comply with emission limits
• The homologation for bivalent operation can cause problems since all OBD requirements must be satisfied. In addition, the technical integration for switching between the two fuels is very complicated
• The car becomes heavier (tanks) and the boot space is reduced in cars that do not have a spare wheel trough
As such if you were to carry out an LPG conversion on your vehicle, this would have an affect on your warranty and any service and maintenance pack, as MINI dealerships are not qualified to service and maintain converted vehicles and therefore would be unable to do so.
Neither a MINI dealership nor MINI can be held responsible for modifications to the vehicle that lead to defects.
We are sorry that we have been unable to offer a more positive response on this occasion.
Yours sincerely
MINI UK
