Diesel ageing
Compared to other fuel types, fuels with a high biodiesel content(> 7 vol.%) may have a higher water absorption
capacity and tend to age (decompose) more rapidly due to lower oxidation resistance. Water and dirt promote
microbial activity and accelerate fuel ageing, which can lead to the vehicle's fuel system being damaged.
Perform the following actions to avoid damaging the vehicle’s fuel system.
If the vehicle is stationaryas from two weeks:
1. Fill fuel tank to maximum level.
2. Start the vehicle at least once a week for around five minutes.
If the vehicle is stationaryas from 45 days:
1. Diesel fuel in the fuel tank may have aged→
.
2. You must replace the diesel in the fuel tank and fuel filter before starting the engine again. The diesel and the
fuel filter should be changed by a suitably qualified workshop.
NOTICE
If the diesel fuel contains water or is decomposed and the engine is started, this can cause serious damage to the
fuel system.
● If water has settled in the fuel filter, it must always be drained.
● Always fill up with high-quality diesel fuel that meets the required specifications.
Water and diesel fuel must never be disposed of in gardens, forests, sewage systems, roads or paths, rivers
or running waters. In order to avoid environmental pollution, disposal must be carried out by a suitably
qualified workshop.
