Oil Recommendations

We recommend the use of Briggs & Stratton Warranty
Certified oils for best performance. Other high-quality deter-
gent oils are acceptable if classified for service SF, SG, SH,
SJ or higher. Do not use special additives.
Outdoor temperatures determine the proper oil viscosity for
the engine. Use the chart to select the best viscosity for the
outdoor temperature range expected.
A
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 Synthetic 5W-30
D 5W-30

How To Check/Add Oil

Before adding or checking the oil
• Place engine level.
• Clean the oil fill area of any debris.
1. Remove the dipstick (A, Figure 3) and wipe with a clean
cloth.
NOTE: On some models, the dipstick is accessible through
an opening behind the operator seat.
2. Insert and tighten the dipstick.
3. Remove the dipstick and check the oil level. It should be
at the top of the full indicator (B) on the dipstick.
4. If low, add oil slowly into the engine oil fill (C). Do not
overfill. After adding oil, wait one minute and then
recheck the oil level.
5. Replace and tighten the dipstick.

Fuel Recommendations

Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane/87 AKI (91 RON). 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 damage
the engine components, which will not be covered under war-
ranty.
To protect the fuel system from gum formation, mix a fuel sta-
bilizer into the fuel. See Storage. All fuel is not the same. If
starting or performance problems occur, change fuel provid-
ers or change brands. This engine is certified to operate on
gasoline.
The emissions control system for this engine is EM (Engine
Modifications).
