7 Mixing Fuel and Refueling the
Cultivator
7.1 Mixing Fuel
A video is available for this chapter
www.stihl.com/sxpweh
This cultivator requires a fuel mixture of gasoline and twostroke engine oil in a ratio of 50:1.
STIHL recommends you use STIHL MotoMix.
If you mix the fuel yourself, use only STIHL two-stroke
engine oil or another high-performance engine oil in
accordance with JASO FB, JASO FC, JASO FD, ISO-LEGB, ISO-L-EGC or ISO-L-EGD.
STIHL specifies STIHL HP Ultra two-stroke engine oil or an
equivalent high-performance engine oil in order to maintain
emission limits over the machine’s service life.
► Make sure that the octane number of the gasoline is at
least 90 RON and the ethanol content is not more than
0000-GXX-6435-A0
10%.
► Make sure the two-stroke engine oil you are using is
suitable for cultivators.
► Depending on the required amount of fuel, determine the
correct amounts of two-stroke engine oil and gasoline in a
mix ratio of 50:1. Examples for fuel mixes:
– 1 liter gasoline, 20 ml two-stroke engine oil
– 3 liters gasoline, 60 ml two-stroke engine oil
– 5 liters gasoline, 100 ml two-stroke engine oil
► Pour two-stroke engine oil into a clean approved fuel
canister first and then add gasoline.
► Thoroughly mix the fuel.
