OIL AND FUEL
Whichever blend of oil and fuel you use, there follows some advice that 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 action at source, 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 blends which have been stored for a long time or which have been exposed to sunlight
in a translucent container. Blend 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.

It is extremely important to avoid switching from synthetic oil to traditional oil. The two types
are not always compatible and, if blended, 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 traditional oil has resulted in problems with the engine.

If the engine has been installed the opposite way up (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 sparkplug
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
Fuel specifications: the octane rating should be minimum: R.O.N.95 or more.
