Lawn-Boy Generation II 2-Cycle Oil is formulated
specifically for Lawn-Boy two-cycle engines and is
available from your Lawn-Boy retailer. Using Lawn-Boy
Generation II 2-Cycle Oil regularly will help keep your
engine clean, reduce spark plug fouling, piston ring
sticking, and pre-ignition. It also minimizes varnish
buildup, combustion chamber deposits, and exhaust port
blockage.
Substitute oils may produce more exhaust smoke, require
more frequent engine service, and reduce engine life.
Note: Failing to use the proper oil or the 32:1
gasoline-to-oil mixture ratio can result in serious engine
damage.
Add Lawn-Boy Generation II 2-Cycle Oil (Fig. 11) or an
equivalent oil to fresh, unleaded gasoline according to the
chart below:

5 gallons (19 liters)
To properly mix the gasoline and oil:
1. Pour half of the desired amount of fresh, unleaded
gasoline into a clean, approved gasoline container.
2. Add the full amount of Lawn-Boy Generation II
2-Cycle Oil (Fig. 11) or an equivalent oil to the
gasoline.

5. Slowly remove the cap and add the remaining amount
of gasoline.
Note: Do not mix gasoline and oil in the fuel tank. Oil at
room temperature mixes easier and more thoroughly than
cold oil. Oil below 32 F (0 C) requires additional mixing.

stabilizer during storage. Do not use fuel stabilizers with
an alcohol base such as ethanol, methanol, or isopropanol.

Generation II 2-Cycle Oil (Fig. 11).
