Fuel Stabilizer: Essential For Pressure Washer Maintenance?

Fuel stabilizers are an essential consideration for pressure washer owners, especially those who plan on storing their equipment for extended periods. Without a stabilizer, fuel can turn stale in as little as 30 days, leading to potential issues with the pressure washer's engine and pump. The stabilizer helps prevent moisture contamination in the fuel tank and carburetor, ensuring the pressure washer starts easily after storage. Additionally, it protects internal components such as pistons and seals from damage during storage. While some people opt to drain their fuel tanks, this doesn't eliminate the risk of moisture contamination. Using a fuel stabilizer is a more comprehensive solution, and products like STA-BIL and Ethanol Shield are specifically designed to keep fuel fresh for up to 24 months. For pressure washer owners, this can mean the difference between a quick start and costly repairs or replacements.

What is fuel stabilizer?

Fuel stabilizers are a solution that provides a protective layer for fuel sitting in a gas tank. They are typically made from petroleum products and work by bonding with gasoline to prevent evaporation. This, in turn, prevents the fuel from forming sticky resins that can ruin a carburetor.

On a chemical level, a stabilizer is a mixture of antioxidants and lubricants designed to repel water and limit evaporation. Fuel stabilizers disrupt the chemical reaction that causes gas to break down, helping to extend the lifespan of fuel.

Fuel stabilizers are particularly useful for those who own seasonal equipment, classic cars, or boats that tend to sit idle for extended periods, usually more than three weeks at a time. They are also beneficial for older engines. Most fuel stabilizer mixtures will preserve fuel for up to a year, and in some cases, even longer with increased dosage.

Using a fuel stabilizer involves adding a measured amount to a nearly empty gas tank, filling the tank with fuel (preferably ethanol-free), and then running the engine for 5-10 minutes to ensure the stabilizer is distributed throughout the fuel system.

Why is it necessary?

Fuel stabilizers are necessary for pressure washers as they prevent fuel from going stale and protect the engine. Without a stabilizer, fuel can turn stale in as little as 30 days, leading to potential issues with the pressure washer's engine.

Fuel stabilizers work by preventing moisture from seeping into the fuel, which can cause contamination in the tank and carburetor. This can lead to gummed-up carburetor issues and make it difficult to start the pressure washer after a period of inactivity.

Additionally, stabilizers can help prevent corrosion and oxidation, providing superior lubrication for pump valves and seals. This is especially important during winter, as water left in the pump can freeze and expand, causing tiny cracks. By using a fuel stabilizer, you can ensure that your pressure washer starts easily and that your engine remains protected during storage.

Furthermore, fuel stabilizers eliminate the need to drain fuel before storing your pressure washer. This saves time and effort, as you won't need to siphon out old fuel and replace it with fresh fuel.

Overall, using a fuel stabilizer is a necessary step in maintaining your pressure washer and ensuring its longevity. It helps protect your investment by extending the life of your engine and preventing potential issues caused by stale fuel.

How to use it?

If you're using a gasoline-powered pressure washer, it's important to maintain the fuel system to prevent engine corrosion and keep the gasoline fresh. Here's how to use a fuel stabilizer to do that:

Firstly, check your owner's manual for maintenance procedures and recommendations for fuel additives. Your manual may recommend a specific type of fuel stabilizer, or an alternative such as ethanol-free, pre-mixed fuel. It's important to follow the manufacturer's instructions for your particular model.

If you're using a fuel stabilizer, make sure you use it before storing your pressure washer for a long period, such as over the winter. Leaving fuel untreated in the pressure washer can lead to corrosion and the formation of varnish in the engine and fuel system.

To use the fuel stabilizer, simply add it to the fuel tank according to the manufacturer's instructions. Typically, you'll add a small amount of stabilizer to a full tank of gas. For example, if you're using Ethanol Shield, you'll need to add half an ounce for every five gallons of gas.

If you didn't treat the fuel with a stabilizer before storing your pressure washer, and the fuel has gone stale, you'll need to drain the old fuel into an approved gasoline container and dispose of it properly. Contact your local recycling center for instructions.

Once you've drained the stale fuel, you can add fresh fuel treated with a stabilizer to get your pressure washer running smoothly again.

What happens if you don't use it?

If you don't use a fuel stabilizer in your pressure washer, the fuel in your gas pressure washer may turn stale. This can happen after just 30 days of downtime. Stale fuel can cause moisture to leach into your fuel, which can lead to issues with your tank and carburetor.

Not using a fuel stabilizer can also result in residual moisture in your pump, which can expand in cooler months and cause tiny cracks in your pump. This can lead to damage and potentially crack valves and seals inside your pump.

Additionally, not using a fuel stabilizer can make it more difficult to start your pressure washer after it has been in storage. The fuel may become gummed up, clogging the carburetor and preventing the engine from starting. In this case, you may need to clean or replace the carburetor, which can be a hassle and incur additional costs.

Overall, not using a fuel stabilizer in your pressure washer can lead to a range of issues, from stale fuel to damage to your pump and carburetor. It is therefore recommended to use a fuel stabilizer to maintain the performance and longevity of your pressure washer.

What are the alternatives?

If you're looking for an alternative to a fuel stabilizer for your pressure washer, there are a few options you can consider:

• Siphon out the old fuel and replace it with fresh fuel. Additionally, you can spray some starter fluid into the carburettor to help with ignition.
• Add a small amount of Seafoam to your fuel, start the engine, and burn the tank of fuel with Seafoam in it. This can help clean up any gumming that may have built up in the fuel system.
• Drain the fuel tank and fill it with good, fresh fuel.
• Use a standard fuel system cleaner to help remove any build-up or gunk in the fuel system.
• If your pressure washer has been sitting for a while, you may need to clean or replace the carburettor.

It's important to note that fuel stabilizers are most effective when used in fuel tanks and engines that are stored for long periods, especially during colder months. If you live in a warmer climate and use your pressure washer frequently, a fuel stabilizer may not be necessary.
