Fuel Recommendations
Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane / 87 AKI (91 RON). For high
altitude use, see below.
• Gasoline with up to 10% ethanol (gasohol) is
acceptable.
NOTICE
Do not use unapproved gasolines, such as
E15 and E85. Do not mix oil in gasoline or modify the
engine to run on alternate fuels. Use of unapproved
fuels will cause damage to engine components,
which
will not be covered under warranty
.
To protect the fuel system from gum formation, mix a fuel
stabilizer into the fuel. See the appropriate
Operator's
Manual
for recommendations. All fuel is not the same.
If starting or performance problems occur, change fuel
providers or change brands. This engine is certified to
operate on gasoline. The emissions control system for
this engine is EM (Engine Modifications).
High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum 85
octane / 85 AKI (89 RON) gasoline is acceptable.
For carbureted engines, high altitude adjustment is
required to remain emissions compliant. Operation
without this adjustment will cause decreased
performance, increased fuel consumption, and increased
emissions. Contact a Briggs & Stratton Authorized
Service Dealer for high altitude adjustment information.
Operation of the engine at altitudes below 2,500 feet
(762 meters) with the high altitude adjustment is not
recommended.
For Electronic Fuel Injection (EFI) engines, no high
altitude adjustment is necessary.
Oil Recommendations
NOTICE
This engine was shipped from Briggs & Stratton without
oil. Equipment manufacturers or dealers may have
added oil to the engine. Before you start the engine for
the first time, make sure to check the oil level and add
oil according to the instructions in this manual. If you
start the engine without oil, it will be damaged beyond
repair and will not be covered under warranty.
We recommend the use of Briggs & Stratton

Warranty
Certified oils for best performance. Other high-quality
detergent oils are acceptable if classified for service SF,
SG, SH, SJ or higher. Do not use special additives.
A SAE 30 -
Below 40 °F (4 °C) the use of SAE 30 will result in
hard starting.
B 10W-30 -
Above 80 °F (27 °C) the use of 10W-30 may cause
increased oil consumption. Check oil level more frequently.
C 5W-30
D Synthetic 5W-30
E Vanguard
