Without proper maintenance, a leaf blower may malfunction or cause personal injury. One of the simplest methods to maintain a Stihl leaf blower blowing in its best is to fill it with the suggested mixture of oil to gasoline. Stihl’s user guides recommend certain measures for refueling, both to its ratio, and for the types of gas and oil to be mixed.
According to Stihl, oil and gas for leaf blowers must be mixed in a ratio of 50 components gas to 1 part oil. This amounts to about 2.6 oz of oil to each gallon of gasoline.
Air Cooled Oil
Stihl creates its own brand of motor oil specifically for use in its own two-stroke machines, such as their leaf blowers. If Stihl oil isn’t available, look for top quality two-stroke lookup engine oil. Do not make the mistake of mixing water-cooled or even mix-engine oils, as they’re intended for use in other vehicles, such as mopeds and snowmobiles.
Simply use unleaded gasoline in Stihl blowers. Additives can harm the motor in the long term, so Stihl proposes using only gas which has an octane rating of 89 or higher. In the event the mid-grade gasoline in your area is of lower octane than 89, use premium gasoline.

The same as oil and water, oil and gas don’t mix naturally and so are quick to separate. Be sure to pre-mix oil and gas into a fresh, fuel-approved container. For the best results, mix only tiny amounts of fuel which are sufficient for many days use and never mix a bigger amount than what you’d use in 3 months. Store any extra fuel mix in a gas-approved container. Stihl recommends pouring the oil into the container first and then including the gasoline. Before applying, thoroughly blend the gasoline and oil mixture by shaking the container. Steer clear of moisture getting into the mixture by keeping the container lid tightly shut.
Always practice caution with your Stihl leaf blower, refueling only when the motor is off and in a well-ventilated area outdoors. To decrease the probability of injury from burns off, unscrew the cap slowly to release built-up pressure in the gas tank. Verify the gas cap is tightened properly after fueling, and walk at least 10 feet from the area where you refueled before starting the motor.
