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.
. Mineral based 2-stroke oil… .Fuel / 2-stroke oil mixture 25:1 Diaphragm, all positions . Auto rewind / recoil type . 600ml Carburetor.
Ensure that the fuel you are using with your Ryobi is the correct mixture of gasoline and 2-cycle lubricant if the engine sputters or smokes while in use. The mixture should be 50:1. If it isn`t, let the engine run until all fuel is used in the fuel tank and fill the tank with the proper mixture.
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.
Mix the fuel at a ratio of 1 part 2-stroke oil to 50 parts petrol, in a clean container approved for petrol.
Mix at 50:1 (20mls oil per 1 litre fuel) when you`re using STIHL 2-Stroke oil.
If you`re using a different brand of 2-Stroke oil, you`ll need to mix at 25:1 (40mls oil per 1 litre fuel). Petrol has limited shelf life (as low as 30 days), so always mix with fresh regular unleaded purchased from a reputable large volume fuel supplier.
If your manufacturer recommends a 50:1 fuel/oil mix, it means you need 50 parts of gas to one part two-stroke oil. To mix one gallon of fuel at 50:1, add 2.6 ounces of two-stroke oil to one gallon of gas, as shown in the chart below.
Petrol Use unleaded petrol intended for motor vehicle use with an octane rating of 91 ([R+M]/2) or higher. Oil Use 2-stroke oil for air cooled engines.
For optimum fuel economy 16-17:1 is usually best, leaner than that and the car will begin to misfire. Maximum power is usually found between 12-14:1, but this may be too lean for safety on many engines. For maximum reliability at full power, air fuel ratios from 10.5-12.5:1 are considered best, depending on the engine.
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.

Fuel line positions ?
ANSWER : The longest fuel line, which has the filter attached to it, goes to the brass fitting furthest from the primer bulb. The short fuel line goes directly under the primer bulb. Which hole to put it in doesn’t matter if the lines are the same size. Just choose the shortest path for each. However, if the lines are different sizes, then the longest line (smallest in diameter), goes in the smallest hole of the tank.Jim
