The correct fuel mix is a ratio of 50:1, (or 50mL of petrol per 1 mL of Stihl 2 stroke oil).

Only use STIHL 2 Stroke oil as it is specially formulated for STIHL equipment and will maximize the life of the engine. (The use of other oils would also present a complication in the event of a warranty issue).

STIHLhave recently released in NZ a fully synthetic 2 stroke oil called STIHL HP Ultra. STIHL HP Ultra is designed to completely burn away at the operational temperature of the engine and is a significantly higher quality compared to semi-synthetic oils.

STIHL are sufficiently confident in the quality of this oil that they will double the warranty period for domestic customers who purchase a container of this oil when they purchase their new machine.

Only STIHL 2 Stroke oil will maximise the life of a STIHL engine.

The key requirements of a 2 Stroke oil are:

• To provide the lubrication the engine requires at its operating temperature. 2 Stroke engines are designed to run at a range of temperatures, from the relatively low temperature of a water cooled engine to the high temperatures associated with high performance sports machines. It is only logical that the manufacturer knows the design and performance temperature of their own machines and ensures that their oil is formulated accordingly.
• It is important for the 2 Stroke oil to leave as little residual carbon as possible in the cylinder. Residual carbon forms an abrasive within the cylinder and if present will cause premature wear. Synthetic oils are more highly refined, more uniform molecular size and out-perform Semi-synthetic oils in many respects.
• Use of non-manufacturers oil in a machine will jeopardise the validity of warranty claims.
• Never use the generic 2 stroke oils – we have experience of these oils causing significant issues in 2 Stroke engines.
