After 2 years and 10+ hours of use, I changed the oil on my pressure washer for the first time. It is a 4 stroke Honda engine, purchased the pressure washer at Costco. Manual calls for 15W40 oil, have lots of 5W30 M1 Extended Performance in my stash, so I drained the FF and added the M1 5W30EP. Ran it for 45 minutes today on the fresh oil and it runs perfect, however...
What is your opinion should I keep it in the washer or should I drain it and run a 40 weight? Please share your thoughts??
