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. 4) or an
equivalent oil to fresh, unleaded gasoline according to the
chart below:
32:1 Gasoline-to-Oil Ratio Mixing Chart
Gasoline
Oil
1 gallon (3.8 liters)
4 ounces (118 ml)
2 gallons (7.6 liters)
8 ounces (237 ml)
5 gallons (19 liters)
20 ounces (591 ml)
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. 4) or an equivalent oil to the
gasoline.
3. Install the cap on the gasoline container.
4. Shake the gasoline-and-oil mixture thoroughly.
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.

IMPORTANT: Do not overfill the fuel tank. The
gasoline/oil mix must have room to expand.
IMPORTANT: Do not use fuel additives except a fuel
stabilizer during storage. Do not use fuel stabilizers
with an alcohol base such as ethanol, methanol, or
isopropanol. You do not need a stabilizer if you use
Lawn-Boy Generation II 2-Cycle Oil (Fig. 4).
6. Clean around the fuel cap (Fig. 6).
