Oil Recommendations

Oil Capacity: See the Specifications section.
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.
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.

Check Oil Level

See Figure: 4
Before adding or checking the oil
• Make sure the engine is level.
• Clean the oil fill area of any debris.
1. Remove the dipstick (A, Figure 4) and wipe with a clean cloth.
2. Install and tighten the dipstick (A, Figure 4).
3. Remove the dipstick and check the oil level. Correct oil level is at the top of the full
indicator (B, Figure 4) on the dipstick.
4. If oil level is low, slowly add oil into the engine oil fill (C, Figure 4). Do not overfill.
After adding oil, wait one minute and then recheck the oil level.
NOTE: Do not add oil at the quick oil drain , if equipped. For location, see Features and
Controls.
5. Reinstall and tighten the dipstick (A, Figure 4).
Low Oil Protection System (if equipped)
Some engines are equipped with a low oil sensor. If the oil is low, the sensor will either
activate a warning light or stop the engine. Stop the engine and follow these steps before
restarting the engine.
• Make sure the engine is level.
• Check the oil level. See the Check Oil Level section.
• If the oil level is low, add the proper amount of oil. Start the engine and make sure
the warning light (if equipped) is not activated.
• If the oil level is not low, do not start the engine. Contact a Briggs & Stratton
Authorized Service Dealer to have the oil problem corrected.

• Use clean, dry fuel, free of moisture or any particulate material. Using fuels outside
the following recommended values may cause performance problems.
• In engines set up to run on LPG, commercial grade HD5 LPG is recommended.
Recommended fuel composition is fuel with a minimum fuel energy of 2500 BTU's/ft³
with maximum propylene content of 5% and butane and heavier gas content of 2.5%
and minimum propane content of 90%.
NG or LPG engines are certified to operate on natural or liquid propane gas. The emissions
control system for this engine is EM (Engine Modifications).
WARNING
The equipment on which this engine is mounted is equipped with an automatic safety
