8.2.1 Engine oil
8.2.1.1
Oil quality
The following engine oil specifications are permitted:
n
Engine oils for four-stroke engines acc. to API-classification SJ
or higher
Avoid mixing of engine oils.
8.2.1.2
Oil viscosity
Since engine oil changes its viscosity with the temperature, the
ambient temperature at the operating location of the engine is of
utmost importance when choosing the viscosity class (SAE-class).
The temperature data of the SAE-class always refers to fresh oils.
In travel operation engine oil ages because of soot and fuel resi-
dues. This adversely affects the properties of the engine oil, espe-
cially under low ambient temperatures.
SAE 10W-30 is recommended for general use.
You may alternatively use 15W-40 (except under low tempera-
tures).
8.2.1.3
Oil change intervals
Oil change interval: semi-annually or every 100 operating hours.
8.2.2 Fuel
8.2.2.1
Fuel quality
Use unleaded gasoline with a research octane number of 91 or
higher (or octane number 86 or higher).
Use unleaded standard grade gasoline with maximum 10 percent
by volume of ethanol (E10) or maximum 5 percent by volume of
methanol.
Methanol must also contain co-solvents and corrosion inhibitors.
Do not use any fuel with a higher ethanol or methanol content.
The use of fuels with a higher ethanol or methanol content will
cause starting and/or power problems or even cause damage in
the fuel system.
