ENGINE PREPARATION
Oil Recommendations
Change and add oil according to chart below. Do not overfill. Use high quality detergent oil
classified "For service SC, SD, SE, SF, SG" as B&S "warranty certified" SAE 30 oil, part no.
100005. Use no especial additives with recommended oils.
(*) Air cooled engines run hotter
than automotive engines. Use of
multi-viscosity oils (10W-30,
etc.) Above 40 °F (4°C) will
result in high oil consumption
and possible engine damage.
Check oil level more frequently if
using these types of oil.
(**) SAE 30 oil, if used below 40
°F (4 °C), will result in hard
starting and possible engine
bore damage due to inadequate lubrication. Check oil level before starting engine. Add oil (If
required) as shown below.
Start and run the engine at idle for 30 seconds. Shut engine off. Wait 30 seconds and
check oil level. Add oil to bring level to Full mark on dipstick, if required.
Oil capacity is about 1.5 quarts (1.4 liters) if engine is not equipped with oil filter. Oil
capacity is about 1.75 quarts (1.7 liters) if engine is equipped with oil filter.
Note :Engine is shipped from factory without oil. Before starting the engine, check oil level.
Fuel Recommendations
The engine will operate satisfactorily using any automobile gasoline. Use clean, fresh, lead-
free gasoline with a minimum of 77 octane. (Leaded gasoline may be used if it is
commercially available, and if lead-free is not available). Purchase fuel in quantity that can
be used within 30 days. DO NOT MIX OIL WITH GASOLINE. B&S do not recommend
using gasoline which contains alcohol, such a gasohol.
If gasoline with alcohol is used, it
must contain less than 10% Ethanol and must be removed from engine during storage. Do
not use gasoline which contains Methanol.
Fuel Level : Do not overfill. Allow space in fuel
tank for fuel expansion.
