I recommend emptying the tank before storing the pressure washer. Doing this will help prevent any deposits from building up in the tank and ultimately prevent your pressure washer from starting.

Also, be sure to disconnect the hose from the petrol pressure washer before starting the cleaning task. It is a must to wipe down all its parts before storage.

So, we suggest you to check the user manual of pressure washer to know about the exact information on what type of gas to be used in the device. In case, if you use any wrong type of fuel, then it damages your engine and the whole machine as well.

How to pick the petrol pressure washers based on terrain?
