. The types of petrol are differentiated
by using the octane numbers (RON) or via

Practical tips
However, the heating power and the propor-
tion of nitr ogen and carbon dio
xide can fluc-
t
uate within the quality groups. Therefore, ve-
hicle consumption can also vary when using
a single type of gas only.
The engine management automatically
adapts to the natural gas used according to
its quality. Therefore, different quality gases
can be mixed in the tank, without the need for
comprehensive draining before applying a
different quality gas.
Natural gas and safety
