"Fuel
The Raket engine works well on unleaded fuel, but we recommend
98 octanes, with a 5 per cent mix of 2-stroke oil. We don’t
recommend the use of so called outboard oil. The engine can also
run on 2- stroke oil intended for extremely low mixture, normally 1
per cent. But, if you use such oil, you must be very careful when
you mix fuel and oil. This is the reason why we recommend this
type of oil only if you get it in small packages ready to be mixed
with 5 or 20 liters of fuel. Ready-to-use oil in such small packages
is available for the Raket engine from Radne Motor."
