When it comes to maintaining the cleanliness of your outdoor spaces, a Simpson pressure washer is a valuable tool. These powerful machines use a combination of water and gas to create high-pressure streams that can wash away dirt, grime, and even tough stains. But what type of gas should you use in a Simpson pressure washer?

The answer is simple: unleaded gasoline with a minimum octane rating of 87. This type of gasoline is readily available at most gas stations and is compatible with the engine of your Simpson pressure washer. It is important to use unleaded gasoline as leaded gasoline can cause damage to the engine and decrease its performance.

Additionally, it is recommended to use fresh gasoline to ensure optimal performance. Stale gasoline, which has been sitting in a can for a long period of time, can lead to difficulties in starting the pressure washer and can affect its overall efficiency. To prevent this, it is best to use fresh gasoline and to refill the tank before each use.

In conclusion, when it comes to fueling your Simpson pressure washer, always use unleaded gasoline with a minimum octane rating of 87 and avoid using stale gasoline. Following these guidelines will help ensure that your pressure washer operates smoothly and efficiently, allowing you to keep your outdoor spaces clean and well-maintained.

Octane Rating

The octane rating of the gas determines its ability to resist knocking or pinging during combustion. It is important to use a gas with the recommended octane rating specified by the manufacturer. Using a lower octane gas can cause engine knocking, which can in turn damage the engine components.

Ethanol Content

Modern gasoline often contains ethanol, which is a renewable fuel made from corn or other plant materials. While ethanol can improve oxygenation and reduce emissions, it can also have detrimental effects on small engines if the percentage is too high. It can cause corrosion, clogs, and other issues. It is crucial to check the recommended ethanol content for your specific pressure washer model.

Consult the owner’s manual or contact the manufacturer to determine the acceptable ethanol content, as it can vary depending on the engine design. If necessary, consider using a fuel stabilizer or ethanol treatment to minimize the harmful effects of ethanol on the engine.

Gasoline Quality

The quality of the gasoline also matters. It is recommended to use fresh gasoline that has been purchased within the last 30 days. Stale gasoline can lead to poor engine performance and starting difficulties. Avoid using gasoline that has been contaminated with water, dirt, or other impurities, as it can cause damage to the fuel system.

Additionally, using gasoline with a high amount of impurities can lead to carbon deposits in the engine, reducing overall efficiency. Using a high-quality, reputable gasoline brand can help ensure better performance and longevity of your pressure washer.

Factor Considerations
Octane Rating Follow manufacturer’s recommendation to prevent engine knocking.
Ethanol Content Check recommended percentage and consider using fuel stabilizers if necessary.
Gasoline Quality Use fresh gasoline from reputable brands to avoid engine damage and poor performance.

By carefully choosing the right type of gas for your Simpson pressure washer, you can ensure its longevity, optimal performance, and efficient cleaning power.

Impact Of Incorrect Gas Type

Using the correct type of gas is essential for the proper operation of a Simpson pressure washer. The manufacturer usually specifies the appropriate gas type in the user manual or on the product label. Failure to use the correct gas can have several negative effects on the pressure washer’s performance and longevity.

1. Decreased Performance

Using the wrong type of gas can result in decreased performance of the pressure washer. The engine may not receive the necessary fuel mixture, leading to reduced power output and lower water pressure. This can make it difficult to effectively clean surfaces or remove tough stains.

2. Engine Damage

Incorrect gas type can also cause damage to the engine of the pressure washer. Some gas engines are designed to run on specific fuel blends, such as regular unleaded gasoline or ethanol-blended fuel. Using gasoline with a higher ethanol content than recommended can lead to corrosion and damage to engine components.

On the other hand, using gasoline with a lower octane rating than required can cause knocking or pinging noises in the engine, indicating internal damage. Continued use of incorrect gas can eventually result in engine failure.

Note: It is important to read the manufacturer’s instructions and follow the recommended gas type to avoid engine damage.

3. Warranty Void

Using the wrong type of gas in a pressure washer can void the manufacturer’s warranty. Most warranties explicitly state that proper fuel usage is required to maintain coverage. If an issue arises and it is found that incorrect gas was used, the warranty may become void, leaving the owner with the financial responsibility of repairs.

Conclusion

Using the correct gas type is crucial for the optimal performance and longevity of a Simpson pressure washer. It ensures proper fuel mixture, prevents engine damage, and maintains warranty coverage. Always consult the user manual or contact the manufacturer for the recommended gas type before fueling your pressure washer.

Tips For Using The Correct Gas

Using the correct gas is essential for the proper functioning and longevity of your Simpson pressure washer. Here are some tips to help you make sure you are using the right type of gas:

1. Check your owner’s manual

Before using your pressure washer, always refer to the owner’s manual for specific instructions and recommendations regarding the type of gas to use. Different models may have different requirements, so it’s important to follow the manufacturer’s guidelines.

2. Use unleaded gasoline

Most Simpson pressure washers are designed to run on unleaded gasoline. It is important to use unleaded gasoline to prevent damage to the engine and reduce the risk of harmful emissions.

3. Use the correct octane rating

Gasoline typically comes in different octane ratings, such as regular (87), mid-grade (89), and premium (91 or higher). Check your owner’s manual to determine the recommended octane rating for your pressure washer. Using a higher octane rating than necessary can be a waste of money and may not provide any additional benefits.

4. Use fresh gasoline

It is important to use fresh gasoline to ensure optimal performance. Gasoline that has been sitting for an extended period can become stale and may cause starting issues or affect the overall performance of the pressure washer. If you are unsure about the freshness of the gasoline, it is recommended to drain the old fuel and replace it with fresh gasoline.

5. Avoid using fuel additives

While some fuel additives may claim to improve performance or cleanliness, it is generally not necessary to use them in your Simpson pressure washer. These additives can sometimes cause more harm than good and may void your warranty. Stick to using clean, fresh gasoline without any additives.

By following these tips, you can ensure that you are using the correct gas for your Simpson pressure washer, resulting in optimal performance and longevity of your machine.
