Things to Examine in a Gas Pressure Washer
You can barely differentiate gas pressure washers as they are functionality and outlook wise pretty similar. For assessment of the all qualitative sides of a gas pressure washer, here we have assembled and discussed some factors.

Spray Pressure
The first thing to scrutinize is the water pressure, as cleaning power is directly proportional to the pressure. But too much pressure can also damage the car paint. The pressure measurement is given in PSI (Pounds Per Square Inch).
The gas pressure washers are always high PSI machines and normally they have 2200-4200 PSI ratings depending on different cleaning requirements. Around 2000 PSI rating is safe for cars. But pressure decreases when you wash your car standing a little far.
Water Amount
The amount of water in the spray is measured in GPM (Gallons Per Minute) rating. This is another key factor in determining the cleaning power. High GPM rating refers to efficient and quick cleaning. Around 2-4 GPM rating is seen usually in gas pressure washers.
Water Source
The water source must meet the GPM rating of your pressure washer or else your machine will burn out soon. If you have a city water supply that is consistent, it will be fine. Well-water supply has few limitations. If you have no such huge source of water than first think of installing a water tank or look for pressure washers with inbuilt water reservoirs if you can compromise with run time.
Engine and Pump
The engine and pump are like the brain and heart of a pressure washer. Depending on the engine quality it can be anticipated that the pressure washer is noise and vibration-proof or not. HONDA and Generac are well-known brands of gas engines. Here, CC rating refers to the swept volume of the engine cylinder.
For generating optimal pressure, the pressure washer must have a good-quality pump. Axial and triplex pumps are generally used here. Triplex cars are designed for heavy cleaning and axial pumps are best suited for light duty.
Portability
Storage and transportation of pressure washers demand lightweight, comfortable handle, and efficient wheel system. The gas-powered pressure washers are comparatively heavy and weigh around 33-147 pounds.
Most of them have rare or both front and rare wheels with 10 inches dimension approx. The pneumatic tires have a risk of punctures as they are air-filled. So, look for quality wheels that can withstand the weight and well compatible even with rough grounds.
Construction
The housing and the connectors must be strong and made of quality material or the whole unit can fall apart after a few use. This is because there are housed heavy machinery inside which creates continuous vibration and shocks. Welded and stainless steel is often seen as frame material and often accompanied by engine mountings to isolate vibration in pressure washers.
Nozzle
Multiple nozzles are included sometimes providing various spray angles. This extends cleaning power by giving you control according to the level of the cleaning task.
Most of them provide 0, 15, 25 and 40 degrees and soap angle. So, you can easily alter the pressure of water spray with these quick connectable nozzle tips.
Hose
Long, good-quality, and flexible hose is another requirement for an extended washing area. Most of the pressure washer has a hose with a 25-50 ft length. So, find out a long enough hose for car cleaning which is abrasion-resistant and flexible.
Storage Compartments
Many pressure washers feature dedicated storage compartments to store the accessories for organized people. This includes a hose holder, nozzle compartments, and storage for other tools. Keeping everything organized makes all the tools handy and available.
Soap Tank
Many pressure washers are featured with inbuilt soap tank or attachments on board. This tremendously facilitates heavy car washing by producing soapy foam on the car surface. Bigger soap tanks have no limitations in run time. So, there is no need for a traditional rug and bucket of soap water.
Extra Features
Along with the main parts, there are few beneficial features seen in pressure washers. adjustable wands are, sensors for an auto-shutdown at low oil-level, bypass system for the pump, an auto-lock system for the trigger, etc. are few of them. So, carefully look for these useful features and have a winner feel after the purchase.
