OIL AND FUEL
Whichever brand of oil and fuel you use, please read the following which will help you keep
the engine in perfect running order.

The presence of impurities in the fuel is the main cause of engine failure. To prevent the
fuel from being contaminated, it is necessary to take care from the beginning, because the
potential risk increases if impurities enter the fuel tank. Always use a clean fuel container
that complies with safety standards. Always filter the fuel when you fill or change the
container. Do not fill the container to the brim; never forget that fuel may increase in
volume.

Do not use fuel/oil mixtures which have been stored for a long time or which have been
exposed to sunlight in a translucent container. Mix the fuel and oil thoroughly before
filling the fuel tank because there is a risk of the two liquids separating in time.

Choose the same type and brand of oil and stick to it unless it causes problems. By doing
so, you will get to know the product well and you will be able to assess whether it suits
your engine. If you change the type of oil frequently and your engine has problems, you
will never know which type of oil is responsible for any problems you may have.

It is extremely important to avoid switching from a synthetic oil to a mineral based oil. The
two types are not always compatible and, if mixed, it is possible that a film may form and
obstruct the engine’s components or cause other problems. As a rule of thumb, 20% of
cases where the user has switched from a synthetic oil to a mineral based oil has resulted in
problems with the engine.

If the engine has been installed inverted (with the spark plug pointing downwards), choose
an oil that leaves few carbon deposits. Oil deposits tend to build up in the lowest parts, for
example, in the spark plug cavity. If these deposits do not burn during normal use, the
spark plug is fouled and this may result in self-ignition. Manufacturers of top brand
lubricants guarantee the quality of their products.
Oil specifications: synthetic oil for two-stroke engines: 50: 1 ratio (Castrol TTS
recommended)
Fuel specifications: the octane rating should be minimum: R.O.N.95 or more.
