What is the best gas-pressure washer? Primarily, you should pay attention to the products of the well-known and trusted manufacturers with a sufficient experience in this branch of industry. Gas-pressure washers are very powerful thus they can deal with a really heavy-duty cleaning routine depending on your needs and applications. That’s why it’s highly important to select a product with suitable power settings.
In particular, if we are talking about gas pressure washers for residential purposes like cleaning the outdoor area of your household, the PSI up to 3500 pressure would be more than enough. It should be equipped with a powerful engine which will enhance cleaning efficiency, thus saving your time and contribute to higher reliability and durability of the gas pressure washer. More than that this equipment should be easy to operate and perform multiple tasks. I believe that Generac SpeedWash 7122 totally meets all the above-mentioned expectations!
Why have I chosen this model? Because it is made by Generac Power Systems, Inc. with its 60 years of experience on the market. They were the first to engineer affordable home standby generators, and is now the # 1 manufacturer of home backup generators. Besides, Generac features a full line of innovative, industry-leading power washers suitable for virtually any application, including the toughest commercial and industrial environments.

All this enable the product to clean up to 50% faster than other cleaning units in the same range.
I guess that back in 1927 Frank W. Ofeldt, a pioneer of a general concept of pressure washers, had no idea about success and high demand for his invention in the present days. Since that time pressure washers have been modified and improved to the state-of-the-art condition.

What should you know about gas pressure washers?
In general, gas pressure washers are perfect for hard to clean areas like those around your house and yard since their power is twice that of the electric counterparts. Gas pressure washers are larger and heavier and mounted on a robust frame with larger wheels.
Gas engines of these washers can produce more power and they are a lot more mobile as they do not need to be plugged in to an electric power source. Since gas engines are more powerful, the pump can generate considerably more PSI and GPM so that they can clean faster and deeper than any electric pressure washer could.
So if you face heavy-duty cleaning from time to time, you will be saved by a gas pressure washer for residential use with its PSI range up to 5000. They must be used outdoor areas because of the emission of carbon-monoxide fumes and higher levels of noise. Of course, they do require a little more maintenance and cost more to operate, but anyway they are worth its price.
Using this type of equipment is quite easy, but it is important that you do it in right way otherwise you could damage the equipment or lose the desired efficiency and effectiveness of a cleaning process. So, keep reading this guide to learn about the essential life hacks on how to maintain and operate your gas pressure friend easily.
What type of gas and oil does a pressure washer use?
Every gas pressure washer is different. Depending on an engine type some operate with regular gasoline, others require using a two cycle mix. Some gas pressure washers use a mixture of gasoline and oil. You must read instruction manual carefully. Using a wrong product or mixing your products the wrong way will damage the engine.
Besides you have to pay an extra attention to fuel requirements, otherwise your gas pressure washer will cease to work. With that said, what kind of oil does a pressure washer use is an important knowledge since oil might affect the functionality of the gas pressure washer.
Fuel type recommendations
- Use fresh, clean, unleaded gasoline with a minimum of 87 octane in a pressure washer. Gasoline with up to 10 percent ethanol (gasohol). Don’t use unapproved gasoline such as E15 and E85.
- Fuel RVP is a critical rating too. Gasoline refineries raise and lower fuel RVP ratings depending on a season with its temperature differences (low RVP for summer fuel and high RVP for winter fuel). This rating is specific for different regions or states.
WARNING: Fuel and its vapors are extremely flammable and explosive. Always handle fuel with extreme care.
Oil type recommendations
For best results, especially if you really don’t want to worry about what type of oil is best suited for the temperature that you are operating your pressure washer in, you should use oil with low consumption. You can use any high quality detergent SAE 30 or synthetic 5W30 oil which is recommended for temperatures above 40ºF. However, if temperature falls below 40 ºF, it is recommended that you use the 10W-30 oil to help your power washer start better.
Before starting your pressure washer, you should always check the oil level. Some washers are equipped with a sight window that allows checking the oil level without opening the cap. Otherwise, you have to open the cap and check the quantity left. The oil should be a transparent yellow / gold color.
Change the oil in a new pressure washer after the first 5 hours of operation. After that, if you live in a region with a moderate climate, you should change your oil every spring, or as soon as you start your unit at the end of winter. During winter, the oil tends to thicken and thus even a properly run pump can be damaged. Hence, always refill accordingly. In the tropics, the oil should be changed every fifty hours.
How To Start A Pressure Washer
Pre-start and starting activities are described in the following steps below:
STEP 1: CHECK GAS AND OIL
Before getting started, always make sure your pressure washer's oil is clean and at the appropriate level. (Always turn the fuel valve to OFF before adding oil.)
STEP 2: ATTACH HIGH PRESSURE HOSE
Fasten the hose you will use to the pump of your washer and connect everything in place so that it is secure. Uncoil and straighten it to prevent tangles. Choose your nozzle and install this properly.
STEP 3: ENSURE WATER SUPPLY SOURCE
Connect a water supply hose to the pressure washer's pump. Turn the water on.
STEP 4: TURN FUEL VALVE TO OPEN & PUT ON / OFF SWITCH IN ON POSITION
STEP 5: START YOUR PRESSURE WASHER
- Pull the engine cord while you are holding spray wand trigger
- Allow engine to run for several seconds, then move the choke to the OFF or RUN position.
- If the pressure washer doesn't start in a few pulls, try one of the following:
- If the rope is difficult to pull, try again after squeezing the trigger to release pressure built up in the pump.
- Check fuel levels and make sure both the on / off switch and the fuel valve are in the correct positions.
How long do gas pressure washers last?
First of all, durability of gas pressure washers depends on an engine model built in the unit. For instance, pressure washers powered by Honda engines are considered to be highly reliable and long-lasting units.
Another factor that can influence durability of a gas-pressure washer is its design peculiarities. As these units have bigger overall dimensions and weight in comparison with electric pressure washers, a heavy-duty robust frame and larger wheels must be provided to enhance their maneuverability and durability.
Besides, gas pressure washers do require maintenance, like refilling with a suitable type of fuel or checking of the oil level, winterizing procedures, etc. But, if you keep up with the routine maintenance, they may last you for many years.
Another reason that could affect negatively pressure washer's life is lack of water in it. Although you can start a pressure washer without water, it is not advisable to do it. When you start a pressure washer without water supply, you are taking a huge risk. The damage will be immediate and irrevocable to the pressure washer's internal mechanisms. Firstly the pump will be damaged, and then other components such as seals, gaskets, etc., may become damaged in a while. The more often you start your gas pressure washer dry, the more damage will be inflicted.
