Fuel Options For Your Pressure Washer: Where To Get It?

If you're looking to fuel your pressure washer, it's important to know that the type of gas you put in it is the same kind you use in a car. The best gas to use in a pressure washer is regular 87 octane gas with no more than 10% ethanol. This is because pressure washers are powered by small 4-stroke engines with low compression, which require low octane fuel. You can buy this type of gas from just about any gas station, but it's recommended to go for a reputable company like Shell, BP, or Exxon.

Where do I get fuel for my pressure washer?

Unleaded fuel is best for pressure washers

Unleaded gasoline offers several benefits over other types of fuel. Firstly, it causes less environmental pollution as it does not release tetraethyl lead, which can pollute the air and cause harmful impacts. Secondly, it offers better health safety as lead is a highly toxic element that can cause cancers and blood-related issues. By using unleaded fuel, you can protect yourself from the poisonous effects of lead.

Additionally, unleaded gasoline is compatible with pressure washers, as they do not accept ethanol-mixed gasoline or diesel. Unleaded fuel also provides better ignition compared to other gases, resulting in improved engine efficiency and longer running times for your pressure washer.

It is important to note that not all pressure washers use unleaded fuel. Some engines can accept both unleaded gasoline and gasoline mixed with up to 10% ethanol (commonly referred to as E10). However, it is always best to refer to your pressure washer's manual for specific instructions on the type of fuel to use.

To maintain the performance and longevity of your pressure washer, it is crucial to use the correct type of fuel and perform regular maintenance. This includes tasks such as checking fluid levels, inspecting debris screens and spray guns, and maintaining the fuel system by using fresh fuel and, if necessary, adding fuel stabilizers.

Gasoline with up to 10% ethanol is suitable

If you're looking to get fuel for your pressure washer, it's important to know that not all pressure washers use the same type of fuel. Gasoline-powered pressure washers are generally more high-maintenance than electric models.

Some pressure washers can use gasoline with up to 10% ethanol (often referred to as E10). This type of fuel is usually acceptable for engines with four cycles, such as the Ryobi 2800 psi washer with a Honda 4 cycle engine. E10 is also suitable for engines with both higher and lower compression ratios. This is because higher octane fuels burn slower and are less likely to cause knocking in high-compression engines, but pressure washer engines typically have lower compression ratios.

Using E10 is a good option if you cannot find ethanol-free gasoline, which is considered the best option for small engines. E10 is better than using fuel with a higher ethanol content, such as E15 or E85, which can damage smaller engines.

If you use E10, it's important to note that it won't store for as long as ethanol-free gasoline, and you may need to clean the carburetor more frequently. Additionally, gasoline degrades over time, so it's best to use fuel that is less than 30 days old. You can also use a fuel stabilizer to extend the shelf life of the fuel.

Non-ethanol gasoline is a good alternative

However, non-ethanol gas tends to be more expensive and may be more difficult to find. It may not provide the same level of performance as traditional gasoline, especially if your engine is designed for gasoline with a specific octane rating. Therefore, it is important to check your user manual for guidance on the best type of fuel for your pressure washer.

If you are unable to find non-ethanol gasoline, or it is not recommended for your machine, you can use regular unleaded gasoline with an octane rating of 87 or higher. This type of fuel is readily available at most gas stations and is the most affordable option. Just be sure to use gasoline that is less than 30 days old, as gas bought at the pump degrades over time and can lead to corrosion and engine damage.

Additionally, you can use fuel additives to help maintain your pressure washer engine. Follow the manufacturer's recommendations, and consider using a fuel stabilizer to prevent engine corrosion and keep the gasoline fresh.

Avoid diesel fuel for pressure washers

Diesel fuel is not suitable for pressure washers with gasoline engines. Diesel engines operate on a different combustion principle to gasoline engines, and using diesel fuel in a gasoline engine can cause severe damage.

If you have a diesel-fired hot water pressure washer, you have a few fuel options, including diesel, kerosene, and home heating oil. However, if you have a gasoline-powered pressure washer, diesel is not the right choice.

Gasoline-powered pressure washers typically require more maintenance than electric models, and it is important to follow the maintenance and safety procedures outlined in the owner's manual. When it comes to fuel, the manual will specify the requirements, and it is crucial to use the correct type to avoid costly repair bills.

The minimum requirement for pressure washer fuel is 87 octane, and the ethanol content should not exceed 10%. Higher octane fuels burn slower but offer no benefit to pressure washers as they have lower compression ratios. Excessive ethanol content (above 10%) can damage small engines, causing corrosion and deteriorating fuel lines.

To maintain the quality of the gas, it is recommended to use it within 30 days as moisture accumulation can lead to engine issues. Storing gas in a cool, dry, tightly sealed container can help, and adding a fuel stabilizer can extend its shelf life.

When it comes to refuelling, most pressure washers have a fuel gauge or transparent fuel tank. If yours does not, be sure to check the fuel level manually before each use, as running out of fuel can lead to engine stall and potential damage.

In summary, diesel fuel should be avoided in gasoline-powered pressure washers, and the recommended fuel type as per the owner's manual should always be used to ensure optimal performance and engine longevity.

Fuel stabilizers can help preserve fuel quality

Fuel stabilizers can be added to fuel to prevent engine corrosion and keep gasoline fresh. They are particularly useful if you are storing your pressure washer for a long period of time. For example, if you are storing your pressure washer over the winter, or for longer than 30 days, it is recommended to treat the fuel with a stabilizer. This will ensure that your pressure washer is ready for your next cleaning project.

There are several fuel stabilizers on the market that can be used for pressure washers, including Sta-Bil Storage Fuel Stabilizer, Ethanol Shield, and Honda Fuel Stabilizer. These products can be purchased from home improvement stores or online.

In addition to using a fuel stabilizer, it is important to perform regular maintenance on your pressure washer to ensure it runs efficiently and lasts longer. This includes checking fluid levels, inspecting debris screens, and maintaining the fuel system. By taking care of your pressure washer, you can extend its life and protect your investment.
