If you're planning on storing your 4-cycle power washer for a few months, it's important to add fuel stabilizer to the gas to prevent moisture from accumulating and causing engine problems. Regular fuel typically contains 90% petroleum and 10% ethanol, and products such as Ethanol Shield can be added to prevent ethanol-related issues. For a 3000 psi gas-powered pressure washer, the manual recommends using E0 or E10 gasoline, containing either 0 or 10% ethanol. It's also important to note that fuel stabilizers should be added to the gas can, and not mixed with lubricant.

How to maintain a 4-cycle powerwasher engine
Maintaining a 4-cycle power washer engine is important to ensure the longevity of the machine. Here are some steps to follow for proper maintenance:
Firstly, always refer to the manufacturer's instructions for guidance on fuel and fuel additives. It is recommended to use gasoline that is less than 30 days old, as older gas can degrade and cause corrosion and varnish build-up in the engine and fuel system. To prevent this, you can add a fuel stabilizer to the gas tank, which will protect the engine when storing the power washer for long periods or over winter. Approximately 15ml of stabilizer should be enough to protect the engine for a few months.
Additionally, always use ethanol-free fuel, or an ethanol shield, to prevent the gas from spoiling and to stop seals from drying out. If you are unable to find ethanol-free fuel, you can opt for regular fuel with 90% petroleum and 10% ethanol, which is widely available at gas stations.
Other general maintenance procedures include regularly checking oil levels, draining water from the system, and keeping the machine clear of any debris. It is also important to ensure there is always water in the system before and while the engine is running, as the water cools the engine.
Finally, when storing the power washer, disconnect all attachments, such as the garden hose and spray gun, and follow the manufacturer's instructions to remove any remaining water from the pump.

When to use fuel stabilizers
Fuel stabilizers are designed to maintain the quality of stored fuel. They are particularly useful for people who own seasonal equipment, classic cars, or boats that tend to sit idle for more than three weeks at a time. Fuel stabilizers are also beneficial for vehicles that are not driven frequently, as they help keep the fuel fresh and protect the engine from corrosion.
The optimal time to add a fuel stabilizer is when fuelling up, especially if the vehicle or equipment will be stored for an extended period. Most fuel stabilizers will preserve fuel for up to a year, but some can last up to two years. Generally, stabilized gasoline should be used within 6-8 months for optimal performance.
Fuel stabilizers are suitable for all kinds of gasoline and diesel engines, including two-stroke and four-stroke motors. They are designed to work with all grades of gasoline, including gasoline that contains ethanol. However, it is important to check the product label to ensure compatibility with the specific type of fuel and engine.
To use a fuel stabilizer, locate your fuel tank’s capacity and calculate the amount of stabilizer required based on the manufacturer's recommendations. Remove the fuel cap and measure out the recommended amount of stabilizer for the volume of fuel in the tank. Turn on the engine for a few moments to allow the stabilizer to disperse and ensure even distribution throughout the fuel system.
By using fuel stabilizers, you can prevent engine problems, ensure smooth starts after periods of inactivity, and extend the lifespan of your fuel.

How to fix stale fuel in a 4-cycle powerwasher
Stale fuel in a 4-cycle powerwasher can cause a host of problems, from clogging injectors to damaging engine parts and causing a loss of power. To fix this, you need to address the stale fuel and take steps to prevent it from happening again.
Firstly, check the fuel. If it is darker in colour, has sediment, or you see water separation, the fuel has likely gone bad. Drain the fuel tank and replace the fuel filter. Refill the tank with fresh, high-quality fuel. If your powerwasher has been sitting for a while, siphon out as much of the old fuel as possible and replace it with fresh fuel.
You can also add a fuel stabilizer to the fresh fuel to help keep it fresh for longer. If you're not going to use all the fuel in a few months, add a stabilizer to prevent it from going stale. Additionally, use a quality gas or diesel additive to your fuel to keep it fresh and prevent clogging.
If bad fuel has contaminated the carburetor, you may need to clean or replace it. Varnish from stale gasoline can build up in the carburetor, reducing the air/fuel mixture reaching the engine. Drop the bowl and clean the float with carburetor cleaner, or replace the carburetor if it's severely clogged.
To avoid stale fuel in the future, ensure you run the powerwasher until it's out of fuel if it's going to sit for a while. Don't let it idle, as this can burn up the pump. Also, turn off the fuel shut-off valve when the engine is not in use, and always relieve pressure by giving one last pull of the trigger.

Ethanol Shield Fuel Stabilizer
If you're not going to be using your 4-cycle power washer for a few months, it's recommended to add fuel stabilizer to the fuel to prevent future engine problems.
For everyday equipment use in all gas engines, use 1 oz of Ethanol Shield per 2.5 gallons of fuel. For storage, use 1 oz per 1 gallon and run the engine to disperse the stabilizer throughout the fuel system. For automotive use, use 1 oz per 10 gallons, and for marine use, use 1 oz per 5 gallons.
One user review states that they use Ethanol Shield in all their small engines, and they never have problems with starting, even after a year. Another review mentions that Ethanol Shield is the best fuel stabilizer on the market for removing moisture from fuel.

How much fuel to leave in a 4-cycle powerwasher
It is important to use the correct type of fuel for your 4-cycle power washer to ensure it functions correctly and to prevent engine damage. The optimal fuel for a 4-cycle power washer contains at least 87 octanes and up to 10% ethanol. This fuel is usually available at your local gas station, and the octane rating and ethanol content should be displayed. If this information is not available, it is best to source fuel from elsewhere.
It is recommended to use the fuel in your power washer within 30 days of purchase. If you intend to store the fuel for longer than this, it should be kept in a cold, dry location, and the container should be well-sealed. You can also add fuel stabilizers to the container to maintain the quality of the fuel.
If you are not going to use all the fuel in your power washer within a few months, it is recommended to add a fuel stabilizer to the tank. This will help to keep the gas fresh and prevent the seals from drying out. If you do not plan on using your power washer for a while, it is best to run the machine until it is out of fuel. However, do not let it idle until it runs out, as this can burn up the pump.
If you forget to add a fuel stabilizer before storing your power washer, you may still be able to get it running. First, siphon as much of the old fuel out of the tank as possible and replace it with fresh fuel. You can also try spraying some starter fluid into the carburettor and firing up the engine to burn off the old fuel. In the worst case, you may need to clean or replace the carburettor.
By following these guidelines for fuel usage and storage, you can help ensure that your 4-cycle power washer functions optimally and avoid potential engine damage.
