Let's Start Here

The Complete Guide On Gas-Powered Pressure Washers 2018

Over the years, professionals and contractors have preferred gas pressure washers to electric pressure washers. The main reasons for this are that gas pressure washers are more:

1. Powerful,
2. Durable,
3. And have a cordless operation.

However, electric washers are slowly closing that gap due to the numerous advantages they offer over their gas-powered counterparts. The most notable benefits of electric washers are that they are more:

1. Affordable,
2. Operate quietly,
3. Weigh significantly less,
4. And require less maintenance

8 Things to Consider When Buying Gas Pressure Washers

All gas-powered pressure washers use internal combustion engines and are generally bigger and much heavier than electric-powered ones. Most of them have inbuilt storage for accessories such as the pressure gun and spray nozzles. The difference is that they come equipped with different features. Below are some of the things you ought to know when shopping for a pressure washer:

Engine Size

Most gas pressure washers use OHV engines from Honda as they are known to be the most reliable. You will also find that most medium-duty pressure washers use engines that range between 180 and 200 CC.

In full CC, means Cubic Centimeters and is the unit measurement that describes the volume of the engine’s combustion chamber. Typically, a 200 CC engine is bigger than a 180 CC engine meaning that it is more powerful and can produce higher pressure levels (PSI.)

Pump Type

The two types of pumps used in gas pressure washers are direct-drive pumps and belt-driven pumps. Below are some of the advantages and disadvantages of each pump:

1. Direct-drive:

On the plus side is that they are compact and affordable. On the negative side is that they vibrate when operational which causes a lot of noise and are prone to overheat when used for extended periods.

2. Belt-driven:

On the positive side, the belt reduces the RPM levels of the engine which allows the engine to run at lower temperatures. This means that they can operate double the amount of time of a direct-drive pump without overheating. Also, the belt absorbs the vibrations thereby reducing the noise when operational. On the negative, belt-driven pumps are much larger to accommodate the belt. Also, adding the belt means more maintenance is required.

Cleaning Power

As stated earlier:

Cleaning Power (CP) = Water Pressure (PSI) x Water Flow Rate (GPM)
Different pressure washers have different cleaning power. For instance, the Ford FPWG2700H-J comes equipped with a smaller 180 CC engine and as such is the least powerful from the lineup featured above:
Ford FPWG2700H-J: Least Powerful
2700 PSI X 2.3 GPM = 6210 CP
Simpson Cleaning MSH3125-S: Most Powerful
3200 PSI X 2.5 GPM = 8000 CP

Build Material – Wheels and Frame

The frame of pressure washers serves two primary purposes. The first purpose is to act as a carriage platform that supports the weight of the pump and the engine. The second purpose of the frame is to protect the vital components of the washer from physical damage by external forces.

Most frames are made of welded steel while others are made out of aluminum. Both materials are sturdy, but aluminum frames are more lightweight which plays a huge role in the washer’s maneuverability. The best carriage frames are equipped with vibration insulation to absorb the vibration from the engine and pump.

Most gas pressure washers come with non-flat pneumatic wheels. The most common wheels are the 10-inch variants, but you will also find some models such as the WEN PW31 that come equipped with 12-inch pneumatic wheels.


The cost of pressure washers is dependent on many factors chief among them being brand recognition. Beware that expensive is not necessarily better. For instance, the WEN PW31 costs over $50 less than the Ford FPWG2700H-J, yet it is more powerful and has better features than the Ford washer.

Can it clean with Hot Water?

Hot water pressure cleaners are standard for industrial settings. They are often regarded as heavy-duty pressure washers. However, you will find some medium-duty machines with the capacity of cleaning using both hot and cold water.

These types of washers are equipped with heating elements that warm the temperature up to 50-degrees C or 140-degrees F above the current temperature. The heated water breaks the stable bonds of dirt, grime, and filth making it easier to dislodge them off surfaces.


When it comes to storing your pressure washer for the winter, the two most important things are; first, making sure that it takes the least amount of space as possible in your garage. Secondly, ensure that it will be ready for use once the winter season is over.

The Ford FPWG2700H-J is by far the best when it comes to saving space in your garage thanks to its fold-down handlebars which make it more compact for storage.

We all know that gasoline can freeze or deteriorate when left sitting in a fuel tank during the entire winter season. For this reason, it is important to drain it from the fuel tank or add some stabilizer to it if you are planning to store your washer for 3 to 4 months. These gas management techniques will ensure that your pressure washer is ready to use after storage.


Warranties are standard in gas pressure washers. However, you will find that different components of the machines have different guarantees. For instance, most engines and pumps have one or two-year warranties.

Most frames have more extended warranties that can go up to five years while accessories such as hoses, nozzles, pressure guns and others don’t come with warranties and even when they do, the guarantees don’t go beyond the 90-day mark.
