What Separates The Best Petrol Pressure Washer From The Rest?

powerful pressure washer

We think that a really good petrol-powered pressure washer should be easy to use, fuel-efficient and powerful enough to do the job it’s intended for. Electric-powered pressure washers are good value for money and many are powerful enough to cope with as much dirt and grime as you can throw at it. The main problems with electric pressure washers are you’re tied by the length of the power cable, and they don’t last more than a couple of years on average.

Petrol pressure washers are much more robust and can last for as long as 15 to 20 years. They can easily have parts replaced if say, the pump develops a fault. Whereas electric models will need to have the pump replaced, making petrol models a greener option when it comes to recycling.

How Do Petrol Pressure Washers Work?

The principles of how pressure washers work are very similar, both electric and petrol-powered pressure washers are fed with low-pressure water which is powered up by a motor and a pump and leaves the machine as high-pressure water. The most notable difference is in power, and when we say power we mean Pounds per Square inch (PSi). 

Petrol models can produce almost double the PSi of electric models which means petrol models clean quicker and more efficiently. The majority of petrol models have a higher flow rate as well, which, when added to the extra power makes cleaning oil, grease or anything else a doddle. Plus petrol-powered models have greater mobility as they are not tied down by power cables.

Petrol-Powered Pressure Washers Buyers Guide

Before you rush into buying a petrol model, there are a few things to think about that might affect your decision. Firstly petrol models are considerably louder than electric models, they are heavier too as they are constructed of metal where electrics tend to be made of plastic. Think about where you’re planning on using your pressure washer the most, if it’s indoors or in an unventilated area, you don’t want a petrol engine pumping out exhaust fumes.

Carbon monoxide is known as the silent killer because you can’t see it, smell it or hear it. That’s what’s in your petrol-powered pressure washers exhaust fumes, so it should only ever be used outdoors. Thinking about fuel, you’ll need to keep petrol, engine oil, and pump oil handy as these will need topping up on occasion.

Plus the engine will need a service at regular intervals, these can usually be done at home, but they take time, energy and money. Here are a few of the relevant points to consider before you buy a petrol pressure washer.

PSi

This is the way the power of the pressurised water is measured. It’s an industry standard measurement and the letters stand for Pounds per Square inch. The higher the PSi the faster the pressure washer will clean the surface.

 Petrol pressure washers have higher PSi than electric models, but not all petrol models are equal. If speed is important to you, then choose a model with a high PSi.

Horsepower

This is how engine power is measured. It goes back to the days of horse drawn carriages, the more horses pulling the carriage, the more power it had. Now it’s used to measure an engine’s power rating. The horsepower will affect fuel consumption but the higher the horsepower the more powerful the engine will be.

Flow rate

Flow rate is usually measured in litres per hour (L/H). This is how much water flows through the machine in an hour. Dependent on how powerful the engine is and how efficient the water pump can deal with the water, will determine the flow rate. Higher flow rate plus high PSi equals more powerful water pressure and a faster cleaning time.

Nozzles

Different manufacturers use different systems for nozzles, most use the colour coded system (shown below), but some just have their own versions that are usually controlled by twisting the nozzle to change spray type (and power level).

Nozzle colour Function
Red (0 degrees)Most powerful, used for hard to clear stains, high-up areas that are difficult to reach
Yellow (15 degrees)For use on concrete, brick, and other hard porous surfaces and stubborn stains
Green (25 degrees)For cleaning painted surfaces,wood, fences,garden furniture etc.
White (40 degrees)For cleaning glass, windows, screens etc.
Black (65 degrees)The least powerful spray, used for applying detergents

Weight

The larger models with the highest horsepower, flow rate etc also tend to be the heaviest machines too. Most have wheels but if they weigh 50 kg you still have to move 50 kg.

Maneuverability

You’re going to have to move your pressure washer about, even if it’s just from the shed to the drive. It needs to be easy to move, most petrol models are on wheels and that makes it easier to move them. But the larger the wheels are, the easier it’s going to be to move, but larger wheels mean it’ll take up more storage space. 

No one model is going to be perfect, you need to find the best compromise for your situation.

Manufacturer

It always pays to go with a well trusted, reputable manufacturer. Not only will they have years of experience in the manufacture of pressure washers, and have updated models with better functionality. But they will also have better customer service departments in the unlikely event of any major problems.

Warranty

Many petrol pressure washers come with a 3 year warranty subject to T&Cs. Some have less but whatever guarantee you receive with your machine is only as good as the company that issues it. That’s why we recommend buying a well known brand from a reputable retailer.

If you do get a problem, you need to have confidence that the company are still running in 18 months to 2 years time.

Petrol Pressure Washer Prices UK

We have deliberately omitted the prices on these petrol-powered pressure washers because just by doing one quick search on google, you can save upwards of between £60 to £80. Look for sales, special offers and free delivery. We have only mentioned the models we consider to be worthy of being included in the best petrol pressure washers UK guide.

There are other makes and models available, but we are confident that the models featured on this page are genuinely available here in the United Kingdom and represent true value for money.

Petrol Pressure Washers Costs To Run

Running costs on petrol pressure washers can be worked out, if you know the prices of water and  petrol and how long it takes to do the job. So let’s imagine it takes 10 minutes to pressure wash your drive. Your flow rate average is 480 l/h which works out at 8 litres per minute.

The average cost of water in the UK is 0.1 pence per litre, so the water used in our example is going to cost 0.8 pence (or less than 1 pence). 

The average price of a gallon of petrol in the UK is £4.50 and the average petrol pressure washer uses around 1 gallon per hour. Which means our 10 minute drive cleaning will cost 75 pence in fuel. 

That gives us a total cost of around 76 pence to clean a drive in 10 minutes. Of course you’ll need to add engine oil, pump oil and maintenance but per usage these are minuscule.
