That first number is the amount of fuel, the second part the two stroke oil. Most power tools work on a ratio of 25/1, so that means you need to mix 25 parts fuel to 1 part two stroke oil. Once done so you then pour that mix into the fuel tank of the unit.
To prevent a costly mistake, always mix the specified 50:1 gasoline-to-oil ratio for the Ryobi SS30 lawn trimmer. This will make for a smooth day working in the yard.
The recommended ratio of fuel mix is 1 part oil to 50 parts petrol. For example, if you are using 5L of petrol, you will need 0.1L (100ml) of 2 Stroke Oil. To mix the fuel, pour the 2 Stroke engine oil into a mixing can that is approved for use with fuel, then add the petrol.
Using the Correct Fuel Mixture

Use automotive unleaded petrol and synthetic 2-stroke oil only. Mix the fuel at a ratio of 1 part 2-stroke oil to 50 parts petrol, in a clean container approved for petrol.

Many two-cycle models require a 40:1 gas-to-oil ratio (i.e. 3.2 fluid ounces of two-cycle oil for every one gallon of gas), but some older models may require a 50:1 or 30:1 ratio. The equipment`s recommended ratio is usually listed on the engine housing. If you don`t see it there, check the owner`s manual.
Use a 32:1 gasoline to oil ratio. One gallon of gasoline combined with 4 oz of two-cycle engine oil.
Most modern chainsaws, string trimmers, leaf blowers and other small-engine two-stroke equipment recommend a 50:1 oil mix ratio, but some recommend 40:1 and older two-stroke equipment might even call for 32:1.
If you can`t find the specific ratio for your mix, 40:1 is accepted as an average ratio for two-stroke engines. This is 125mls of two stroke oil to 5L of fuel.
For a mixing ratio of 1 : 50 you need 5 litres of high-octane gas and 0.10 litres (100 ml) of STIHL two-stroke oil.
To use this blower you need a 50:1 fuel to oil ratio.
