MY CAR HAS AN LPG CONVERSION.
RECENTLY MY TANK PER MILES RATIO HAS REDUCED BY APPROX. 20 - 25%.ANY IDEAS WHAT COULD BE WRONG?

KELVIN JAMES, May 2008

a drop of this amount is nearly always some form of leak in the system, you need to get a leak test carried out, if not a leak then without knowing what system is fitted to your vehicle i.e. venturi or sequential injection, its difficult to come up with any suggestions
