Understanding Oil Capacity
The Briggs & Stratton 18.5 HP engine is known for its power and reliability, but it requires proper maintenance to deliver its best performance. One crucial aspect of this maintenance is ensuring the right oil level. The oil capacity is the amount of oil the engine’s sump can hold, which typically varies depending on the model and specific engine.
For most Briggs & Stratton 18.5 HP engines, the oil capacity is around 1.2 quarts. However, it’s crucial to consult the owner’s manual for your specific engine model to get the precise oil capacity. You can find these manuals online or through the Briggs & Stratton website.
Why is the correct oil capacity important?
The oil plays many vital roles in the engine, including:
- Lubricating moving parts: Oil reduces friction between moving components, minimizing wear and tear.
- Cooling the engine: Oil carries away heat generated during combustion, preventing overheating.
- Cleaning the engine: Oil suspends and carries away debris and contaminants, keeping the engine clean.
- Protecting against corrosion: Oil forms a protective layer on engine surfaces, preventing rust and corrosion.
If the oil level is too low, critical components can experience excessive wear, leading to engine damage or even failure. Conversely, an overfilled crankcase can cause oil to be forced out through seals or even damage the engine.
Choosing the Right Oil for Your Briggs & Stratton 18.5 HP
Just as important as knowing the oil capacity is choosing the right type of oil. Briggs & Stratton recommends using oil that meets the American Petroleum Institute (API) service classification SG, SH, SJ, SL, or SM. These classifications indicate the oil’s ability to meet specific performance standards required for gasoline engines.
In addition to these classifications, you might also encounter these designations on oil bottles:
- SAE viscosity grade: This indicates the oil’s thickness at different temperatures (e.g., SAE 10W-30, SAE 5W-20). For your Briggs & Stratton 18.5 HP engine, refer to your owner’s manual for the recommended viscosity grade. Generally, a multi-grade oil is recommended for its ability to perform well in various temperatures.
- Energy conserving (EC): This designation indicates that the oil meets specific requirements for fuel efficiency.
- High mileage (HM): This designation signifies that the oil is formulated for engines with high mileage, providing additional protection against wear.

Tips for Checking and Changing the Oil in Your Briggs & Stratton 18.5 HP
Now that you understand the importance of oil capacity and how to choose the right oil, let’s move on to the practical aspects of checking and changing the oil.
How to check the oil level:
- Park your equipment on a level surface. Ensure the engine is cool, as hot oil can give inaccurate readings.
- Locate the dipstick. It’s usually a yellow or orange metal rod with a handle on top.
- Pull out the dipstick and wipe it clean.
- Reinsert the dipstick fully and pull it back out.
- Check the oil level on the dipstick. The oil level should be within the “Full” and “Add” markings on the dipstick. Refer to your owner’s manual for specific details about checking the oil level on your model.
How to change the oil:
- Park your equipment on a level surface and ensure the engine is cool. For safety, wear protective gear such as gloves and eye protection.
- Locate the oil drain plug. It’s typically located at the bottom of the engine block, usually with a bolt head.
- Place a drain pan under the drain plug. This will catch the used oil as it drains.
- Carefully loosen the drain plug using a wrench or socket. Be gentle to avoid stripping the threads.
- Let the oil drain completely. This may take a few minutes.
- Replace the drain plug and tighten it securely.
- Locate the oil fill cap. It’s typically on the top of the engine block.
- Pour the correct amount of oil into the engine. Refer to your owner’s manual for the correct oil capacity. If adding oil from a bottle, pour it slowly to avoid overfilling.
- Once the oil is poured, check the oil level using the dipstick. Add more or remove oil as necessary until the level reaches the “Full” mark.
- Start the engine for a few seconds to distribute the oil. Check the oil level again and top off if needed.
- Dispose of the old oil properly. Do not pour it down drains or into the ground.
Tips from a Briggs & Stratton Expert
Here are some additional tips to ensure your Briggs & Stratton engine is well-maintained:
- Change the oil regularly. This is crucial for maintaining engine performance and preventing damage. How often you should change your oil depends on various factors, including engine use, environment, and type of oil. Refer to your owner’s manual for specific recommendations.
- Use high-quality oil. Always use the oil recommended by Briggs & Stratton for your specific engine model.
- Clean the air filter regularly. A clean air filter ensures that the engine gets enough clean air to operate efficiently.
- Inspect the spark plug regularly. A faulty spark plug can cause misfiring, impacting engine performance.
- Keep the engine clean. Remove any grass, dirt, or debris that can hinder cooling or cause damage.
FAQ – Briggs & Stratton 18.5 HP Oil
Q: What if I accidentally overfilled the oil?
A: If you overfill the oil, it can lead to problems. An overfilled engine can cause oil to be pushed out through seals, leading to leaks and potential damage to the engine. If you suspect you have overfilled the oil, the best course of action is to drain some of the excess oil by loosening the drain plug slightly and allowing a small amount to drain out. Then, check the oil level again to ensure it’s within the correct range.
Q: How often should I change the oil in a Briggs & Stratton 18.5 HP engine?
A: The frequency of oil changes depends on the engine’s use and operating conditions. However, a general recommendation is to change the oil every 50 hours of operation or once per season. Consult your owner’s manual for specific recommendations based on your engine model and usage.
Q: What if I can’t find the recommended oil?
A: If you can’t find the exact oil type recommended by Briggs & Stratton, select an oil that meets the API service classifications mentioned earlier (SG, SH, SJ, SL, or SM) and has a similar viscosity grade. Ensure it’s a high-quality oil designed for gasoline engines.
Q: Is synthetic oil better than conventional oil for a Briggs & Stratton 18.5 HP engine?
A: Synthetic oil offers several benefits over conventional oil, including extended oil change intervals, better protection against wear and tear, and improved performance in extreme temperatures. However, it is generally more expensive. Ultimately, the choice depends on your budget and usage pattern. Consult your owner’s manual for specific recommendations for your engine.
