RON factor for determining fuel quality

Fuels with a low octane number may be the cause of the following problems.

- High fuel consumption

- Reduced tractive power

- Driving operation malfunctions

- Poor start-off characteristics

The RON factor serves the purpose of determining the fuel quality used. The reference values refer to the following:

RON factor

Refuelled fuel quality

0 to 0.2

RON 98

0.2 to 0.6

RON 95

0.5 to 1.0

RON 91

These reference values apply at outside temperatures higher than 25 °C. At lower temperatures, knocking occurs at a later point and results in lower RON factors.
