Oil viscosity
Choose the oil viscosity in dependence on the ambient tempera-
ture at the operating location of the engine (see diagram).
SAE10W-30 is recommended for general use under any tempera-
ture. When using single purpose oil you must choose the correct
viscosity for the average temperature in the area of use.
Occasional falling short of the temperature limit (e.g. use of SAE
15W-40 down to -15 °C (+5 °F)) may effect the cold starting ability
of the engine, but will not cause any engine damage.
Temperature related lubrication oil changes can be avoided by
using multi-purpose oils. The following oil change intervals apply
also when using multi-purpose oils.
Oil quality
You should preferably use oils of API-quality class SF/SG or
higher.
Lubrication oil change intervals
6 months or 100 operating hours
When changing to a higher alloyed oil quality after a
longer period of operation, it is recommended to per-
form the first oil change of the higher quality oil already
after 25 operating hours.
Quality
Use automobile gasoline (preferably unleaded fuel or fuel with a
low lead content, in order to reduce the combustion residues to a
minimum).
Do not use oil-gasoline mixes or contaminated gasoline. Protect
the fuel tank against dirt, dust or water.
Alcohol containing gasoline
If you decide on using alcohol containing gasoline (Gasohol), you
should make sure that the octane number is at least as high as for
unleaded gasoline.
There are two types of "Gasohol" available: one contains ethanol
and the other one methanol. Do not use "Gasohol" with more than
10% ethanol. Do not use any gasoline with admixed methanol
(methyl or methyl alcohol), which does not contain solvents or cor-
rosion protection for methanol. Do not use gasoline with more than
5% methanol, even if it contains solvents and corrosion protection
agents.
