LPG quality and consumption
Quality requirements for LPG are regulated for all Europe in DIN EN 589 and
permit the use of LPG throughout Europe without any problems.
LPG is a mixture of propane and butane.
A difference is drawn between winter gas and summer gas. Winter gas has a
higher proportion of propane gas. As a result, the driving range of winter
gas may be lower (due to increased consumption) than that of summer gas.
The vehicle's engine management adapts automatically to the LPG used.
Therefore, both types of LPG can be mixed in the tank, without the need for
comprehensive draining before applying a different quality LPG.

ately by a specialised workshop.
