Power washers that work on fuel need a fuel stabilizer in the fuel tank to protect the fuel system. Fuel stabilizer breaks down sledge and water in ethanol and prevents fuel problems. This allows the engine to burn up smaller particles safely and increase the performance and efficiency of the engine. It also prevents fuel lines from getting clogged during storage.
You can add pump saver oil or RV antifreeze to the pump. Check the manual of your pressure washer to make sure you follow the manufacturer’s directions and use the correct pressure washer pump saver.
Fuel stabilizer prevents the gasoline fuel from degrading in the fuel tank. Also, it prevents harmful varnish or gum from forming inside the engine.

You can use a funnel or a piece of garden hose to fill the pump with solution. Or you can fill the pump inlet with R.V. antifreeze or Pump Saver until it runs out of the outlet i.e. where the high pressure hose is connecting to the pump.
