Gas Pressure Washer Buying Guide & FAQ
Features To Look For In Gas Pressure Washers
Pressure - With pressure comes power, and the more pressure your gas washer produces, the more powerful the cleaning effect can be.
The measurement for pressure is pounds per square inch (PSI), with the higher numbers denoting more water pressure. It might be tempting to invest in a pressure washer that has the highest psi rating, but this isn't always ideal, especially if you plan on using it to clean delicate surfaces. You should look for an adjustable pressure system for domestic needs, whereas professionals may prefer the most powerful options to deal with the most stubborn jobs.
Portability - As gas pressure washers come with an engine, they are not as portable as the streamlined and lightweight electrical options. Despite this, you can still find gas pressure washers with exceptional portability.
Look for wheels that can handle a range of terrain, and also consider checking to ensure that you can replace the wheels in the future if needed.
Flow Rate - The flow rate signifies how much water it releases. Gallons Per Minute (GPM) is the common name for this feature and should be carefully considered when selecting a unit. An increased flow rate will cause more water to pump out as the machine operates, which can increase the pressure and make it more powerful.
Although a high flow rate sounds appealing, it also means you will use more water. If you have a built-in tank, this means you need to refill it more often. If you are using the spigot, it could cost you more money. Try to find a pressure washer that provides a balance between the two.
Fuel Efficiency - Fuel efficiency is vital when looking for the best gas pressure washer. High fuel efficiency is not just helpful to your checking account, as you won't need to refill the tank as often, but it is also good for the environment.
A pressure washer with excellent gas efficiency means you can complete your cleaning jobs quickly without needing to refill the tank halfway through the task.
Price - You should always consider cost when purchasing any product, but with something like a gas pressure washer that you will likely keep for many years, you'll want to be sure you spend an appropriate amount of money for your long term goals with the tool.
Consider your budget, as well as how often you are likely to use it. If you are going to use it every day, you may be better off spending a little more to get additional features. However, if you will only use it a few times a month or year, then more affordable options might the financially sound decision. If you find you use it more often than expected, then you can always upgrade later on.
Gas Pressure Washer FAQ
Q: What is a gas pressure washer?
A: A gas pressure washer is a cleaning device that uses pressurized water to clean surfaces. A combustion engine powers the compressor and pressurizes the water.
Gas-powered pressure washers boast a range of benefits that you can't get from electric alternatives. Sure, gas-powered models aren't as environmentally friendly, and if you're not used to using one, they can be a little bit more work to maintain, but you'll enjoy far more pressure than electric models.
Q: What kind of gas does a pressure washer use?
A: Every engine is different, so it's essential to look closely at the model you are considering purchasing.
Almost all gas pressure washers use four-stroke engines; you fill the fuel tank with high-quality unleaded gasoline and change the motor oil occasionally. Higher quality fuel reduces the risk of clogging anything in the fuel system or causing pre-detonation, which can severely damage an engine.
If the gasoline pressure washer sees intermittent use, with long periods of being idle, it's best to use gas treatments specifically made to stabilize and reduce moisture absorption by the fuel to prevent gumming up the fuel delivery system.
Q: Do gas pressure washers need oil?
A: Yes, gas pressure washers do need oil. You need to keep the engine lubricated to ensure consistent performance. Without it, you risk damaging the engine, which means you could potentially waste hundreds of your hard-earned dollars.
But this still doesn't entirely answer the question. You know that gas pressure washers require oil, but what type of oil? When picking the right gas pressure washer, you need to consider the kind of oil it uses, too. Follow the recommended specifications for the oil to prevent potential damage and adhere to the suggested oil changing schedule.
Q: Can I use regular gas in my pressure washer?
A: As we briefly touch on above regular gas for pressure washer models is possible, but this is only with specific models. You must check to ensure that you are using the right type of gas.
It's best to use ethanol-free gas, as ethanol-based products can damage the small engines that gas pressure washers use. You should also add a fuel stabilizer when appropriate to enhance performance and reduce the risk of problems.
Q: How long can you run a gas pressure washer?
A: Although gas pressure washers are more powerful compared to electric models, you can't run them for as long as their electric counterparts. There are a few reasons for this.
For one, the detergent and water tank might not have the capacity to handle the extended use. And the run time is determined by fuel capacity, unlike electric pressure washers, which have an unlimited potential run time.
