What to consider when buying petrol pressure washer machine?


The first thing to consider before purchasing a petrol pressure washer is the horsepower (HP) rating of the engine. This is because the engine is in charge of the pressure capacity and volume of the machine. The pressure rating of the machine should be proportionate with the horsepower.

Always inspect pressure washers for their horsepower, gallons per minutes (GPM), and pounds per square inch (PSI). Even though washing vehicles don’t require using a very powerful pressure washer, it should be at least 7HP or more, and for commercial use, the HP should be 13 or more.   


As we’ve noted above, the pressure is measured in pounds per square inch abbreviated as PSI. Note that PSI is not the most important feature of a pressure washer machine but the horsepower and volume are.

A simple way to measure the petrol pressure washer’s cleaning power is by multiplying the PSI with the GPM. The value that you get will indicate how effective the pressure washer is in performance. And together with the HP, you will have an estimate of how much power a particular petrol pressure washer has.


The volume the machine has is crucial as it will determine how many cars you can wash within a short period of time. The volume produced by a pressure washer can be measured in gallons per minute. The GPM determines how much water the petrol pressure washer can discharge per minute. Besides the PSI rating, the GPM is another effective barometer of the machine.


The pump is a very vital part of the petrol pressure washer machine. Therefore, when picking a pressure washer, you should check and ensure that it is a quality one. Don’t always go for the cheaper pressure washer pumps as they are unreliable and don’t last long.

High-end pumps perform better, have a longer service life, and their spare parts can be found easily. A good pump should have a brass head, ceramic plunger, and thermal relief valves.

Prior to selecting a pressure washer pump, ask if it is built by the manufacturer or acquired from a third party supplier. Pick a pressure washer pump from a reliable and notable brand.

Horizontal or Vertical shaft

This is one of the least known features of the pressure washer pump. Horizontal shafts are the most reliable but they are quite expensive, while the vertical shafts are cheaper but with shorter service life. As a result, if you want a petrol pressure washer pump that lasts longer, then the horizontal shaft is the best option for you.


The petrol pressure washers that we’ve discussed above are all great for a mobile car washing business. It all depends on what features or the power you need for your pressure washer. Pick the right pressure washer for your car wash business as there are no all-size-fits all unit.

Inspect the pressure washer rating and horsepower before buying it. If you handle a lot of heavy vehicles, then you may need the most powerful pressure washer. Hope you’ve found this review to be helpful? Feel free to leave a question or comment below!
