NEW: Review of our new STIHL Pressure washer BR800
Each of our pressure washing outfits consists of two machines. A 13 horsepower Dewalt with a Honda motor, and a small 6.5 horsepower machine as a backup. We avoid losing time due to equipment malfunction by always having two machines on the job site. The larger machine has a drain plug while the 6.5 Honda requires us to get creative in order to remove the oil. Let’s talk about how to change motor oil on a Dewalt pressure washer.

How often should you change the oil in a pressure washer?
We change ours every 6-8 houses. Each house takes an average of 5-6 hours, so the oil in our machines is changed after every 30-40 hours of use. The machines in the photos are 6 and 10 years old and they have both worked flawlessly the entire time, with minimum maintenance.
What type of oil to use in pressure washers?
We use automotive 10W-30, and as I mentioned we have had great results for several years.
What you need:
Wrench to undo the drain
Container to hold the used motor oil
Motor oil 10W-30 (automotive engine oil)
Funnel
PVC pipe for the machine with no drain
Cleanup rags
