and must always been run using a mixture of gasoline and
two-stroke engine oil. It is important to accurately measure
the amount of oil to be mixed to ensure that the correct
mixture is obtained. When mixing small amounts of fuel, even
small inaccuracies can drastically affect the ratio of the
mixture.

Gasoline
The lowest octane recommended is 87 ((RON+MON)/2). If
you run the engine on a lower octane than 87 it can result in
knocking. This gives rise to a high engine temperature, which
can result in serious engine damage.
