Oil Recommendations
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.
Outdoor temperatures determine the proper oil viscosity for the engine. Use the chart to
select the best viscosity for the outdoor temperature range expected.
*
Below 40°F (4°C) the use of SAE 30 will result in hard starting.
** Above 80°F (27°C) the use of 10W-30 may cause increased oil consumption. Check
oil level more frequently.
How To Check/Add Oil - Figure 2
Before adding or checking the oil
Place engine level.
•
Clean the oil fill area of any debris.
•
1. Remove the dipstick (A) and wipe with a clean cloth (Figure 2).
2. Completely insert the dipstick.
3. Remove the dipstick and check the oil level. It should be at the FULL mark (B) on the
dipstick.
4. If the oil is low, remove the oil fill cap (J).
5. Remove the dipstick. Pour the oil slowly into the engine oil fill (C). Do not overfill.
Important: When adding oil, adequate venting is required as follows:
Remove the dipstick.
•
Make sure adequate clearance (D) is maintained between the oil fill device (E)
•
and the engine oil fill (C). See Figure 3.

6. Install and tighten the oil fill cap.
NOTICE: Before starting the engine, wipe the engine clean of any spilled oil.
7. After adding oil, install the dipstick. Start and run engine at idle for five minutes. See
the How To Start The Engine section. Shut off engine. Wait three minutes and
check oil level. If required, add oil to bring oil level to the FULL mark (B) on the
dipstick (Figure 2).
8. Install the dipstick.
Oil Pressure
If the oil pressure is too low, a pressure switch (if equipped) will either stop the engine or
activate a warning device on the equipment. If this occurs, stop the engine and check the
oil level with the dipstick.
If the oil level is below the ADD mark, add oil until it reaches the FULL mark. Start the
engine and check for proper pressure before continuing to operate.
If the oil level is between the ADD and FULL marks, do not start the engine. Contact
any Briggs & Stratton 3/LC Authorized Dealer to have the oil pressure problem
corrected.
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) or up to 15% MTBE (methyl tertiary
•
butyl ether) is acceptable.
CAUTION: Do not use unapproved gasolines, such as E85. Do not mix oil in gasoline or
modify the engine to run on alternate fuels. This will damage the engine components and
void the engine warranty.
To protect the fuel system from gum formation, mix a fuel stabilizer into the fuel. See
Storage. 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 3,000 feet (900 meters), a minimum 85 octane/85 AKI (89 RON)
gasoline is acceptable. To remain emissions compliant, high altitude adjustment is
required. Operation without this adjustment will cause decreased performance,
increased fuel consumption, and increased emissions. See a Briggs & Stratton 3/LC
Authorized Dealer for high altitude adjustment information.
Operation of the engine at altitudes below 2,500 feet (762 meters) with the high altitude
kit is not recommended.
How To Add Fuel - Figure 4
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When Adding Fuel
Turn engine off and let engine cool at least 2 minutes before removing the fuel
•
cap.
Fill fuel tank outdoors or in well-ventilated area.
•
Do not overfill fuel tank. To allow for expansion of the fuel, do not fill above the
•
bottom of the fuel tank neck.
Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition
•
sources.
Check fuel lines, tank, cap, and fittings frequently for cracks or leaks.
•
Replace if necessary
If fuel spills, wait until it evaporates before starting engine.
•
1. Clean the fuel cap area of dirt and debris. Remove the fuel cap (A, Figure 4).
2. Fill the fuel tank (B) with fuel. To allow for expansion of the fuel, do not fill above the
bottom of the fuel tank neck (C).
3. Reinstall the fuel cap.
Coolant Recommendations
Coolant capacity (see the equipment manufacture's manual)
NOTICE: This is a liquid-cooled engine. A 50/50% mixture of phosphate-free antifreeze
and tap water is required for cooling, rust resistance, and lubrication of the water pump.
