ENGINE PREPARATION
Oil Recommendations
Change and add oil according to chart below. Do not overfill. Use high quality
detergent oil API classified “For service SC, SD, SE, SF, SG”. If oil remains in the
engine, oil viscosity must be suitable for the lowest temperature at which the engine will
be operated in service. Use no special 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).
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.
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 85 octane for overhead valve engines. Leaded
gasoline may be used if it is commercially available, and if lead-free is not available.
Use of lead-free gasoline results in fewer combustion deposits and longer valve life.
Purchase fuel in quantity that can be used within 30 days. This will assure fuel
freshness and volatility tailored to the season.
DO NOT MIX OIL WITH GASOLINE
.
B&S does 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.
