3. Fuel
The two-stroke engine in your paramotor requires using oil-petrol mixture in
1:66 (1.5%)
ratio during regular usage and
1:50 (2%)
when you break in the engine.
Attention: Remember to use only unleaded petrol with an octane rating minimum 91.
In order to correctly prepare the fuel-oil mixture, you should use a special canister.
Warning: You should not mix the fuel with oil in the paramotor’s fuel tank, especially if
the tank was empty before refueling.
You should only use
two strokes synthetic or semi-synthetic oils
. Try to find out
what oil grades are available and popular in the place where you live or in the area where
you want to fly on a regular basis. If you choose a particular oil grade try not to change it. If
it is necessary, try to change it as rarely as possible. The Nitro 200 and Tornado 280 engines
are not designed to work with marine or mineral oils!
Warning: Mixed fuel loses its properties with time. Do not use the mixture that has
been sitting for over a month. Try to plan the amount you will need for your flight and
prepare only as much mixture as needed. If you are going to store the paramotor for a long
time, you should empty the tank completely.
The majority of contaminations that get inside the fuel tank come from a contaminated
funnel. After filling the tank, petrol immediately evaporates from the funnel surface and it
leaves a thin oil layer. Dust and various small and big molecules stick to this layer. Some of
them get inside the fuel tank because they cannot be stopped by the filter. These
contaminations get into the tank during the next refill. That is why one of the most
important aspects of keeping the tank clean is protecting the funnel from dirt in between
refills. This task is very often neglected by the users.
We strongly recommend to pre-filter the mixture before pouring it into the tank.
Poor quality of the fuel or storing it in dirty containers are the most common causes of
engine problems.
Warning: Fuels are extremely flammable liquids and their fumes are
explosive. You mustn’t use open flame while preparing the mixture, refueling or
when you are close to the place where you store it. You should handle fuel very
carefully. Do it only in well-ventilated places or in the open air.
