Why Use 93 Octane Gasoline?

 

**Importance of Using 93 Octane Gasoline in Water Cannon Pressure Washers with Overhead Valve Honda Engines & Issues with Ethanol**

Using the correct type of fuel for your pressure washer is a crucial element to ensure its optimal performance. This tutorial will explain why it is recommended to use 93 octane gasoline in your Water Cannon pressure washer fitted with an overhead valve Honda engine, as well as address the problems associated with ethanol.

**Why Use 93 Octane Gasoline?**

1. **Improved Performance**: Higher octane gas like 93 octane can better withstand high compression before igniting, which is optimal for engines like those found in Water Cannon pressure washers that run at high compression ratios. Improved compression leads to more power output and better engine efficiency.

2. **Protects Engine**: Additionally, use of high octane fuel helps prevent 'engine knocking' or 'pinking', which is premature fuel ignition in the combustion chamber. This is crucial to maintain the health of the engine and to avoid damages.

3. **Enhanced Lifespan**: Regularly using 93 octane gasoline can also help in extending the life of your engine. By reducing 'knocking' and running more efficiently, your engine will experience less wear and tear over time, leading to a longer engine life.

**What's the Issue with Ethanol?**

Ethanol-blended fuels are common, but they can create problems when used in engines like those in Water Cannon pressure washers:

1. **Decreased Performance**: Ethanol contains less energy per gallon than gasoline, which can result in decreased performance and reduced fuel economy.

2. **Potential Damage**: Ethanol is a solvent and can loosen debris lodged in fuel systems, leading to clogs. It may also cause corrosion in the fuel system, leading to further engine damage.

3. **Water Attraction**: Ethanol attracts moisture. This can cause phase separation in the gas tank where water saturates the ethanol and sinks to the bottom of the tank, leading to serious engine problems.

To ensure the performance and extend the lifespan of your overhead valve Honda engine, it's advisable to use 93 octane gas and minimize the use of ethanol-blended fuels. Always refer to your engine's manual for the manufacturer's recommendations on fuel types and proper usage.

Extending the life of your HONDA GX engine

 

The Honda GX 390 is a powerful, reliable engine commonly used in a variety of applications, including powering pressure washers, generators, and pumps. To ensure that your engine runs smoothly and lasts for a long time, it's important to properly maintain it.

Here are some steps you can take to maintain your Honda GX 390 engine:

1- Check the oil level regularly: The oil level in your engine should be checked at least once a month, or before each use if the engine is used frequently. The oil should be filled up to the upper level mark on the dipstick. If the oil level is low, add oil to the proper level. It's also important to use the correct type of oil, as specified in your engine's owner's manual.

2 - Change the oil regularly: The oil in your engine should be changed every 100 hours of use or annually, whichever comes first. Old oil can contain contaminants that can damage your engine, so it's important to change it regularly to ensure your engine runs smoothly.

3- Keep the air filter clean: The air filter in your engine prevents dirt and debris from entering the carburetor. Over time, the filter can become dirty, which can restrict airflow to the engine and reduce its performance. The air filter should be checked and cleaned every 25 hours of use or annually, whichever comes first.

4- Check the spark plug: The spark plug is responsible for providing the spark that ignites the fuel in the engine. Over time, the spark plug can become fouled or worn, which can cause engine misfires or difficulty starting. The spark plug should be checked and cleaned or replaced as needed.

5 - Keep the cooling system clean: The cooling system in your engine keeps the engine from overheating. Over time, dirt and debris can accumulate in the cooling system, which can restrict airflow and reduce the engine's performance. The cooling system should be checked and cleaned regularly.

6- Check the valve clearances: As per instructions in the manual, check and adjust the valve clearances periodically. It is recommended to check them every 600 hour of use or annually. This is to maintain the engine performace and reduce the wear on the valve train.

By following these simple steps, you can keep your Honda GX 390 engine running smoothly and extend its lifespan. It's also important to refer to your engine's owner's manual for specific maintenance instructions, as well as any
