-- More information below and Links if you want to support me :) Quick oil change. I looked at the pressure switch to but didnt seem to help.. Its broken i think and need to order a new one. When it comes to oils most of them do fine with normal motor oil. I used some 10/40 motor oil to mine and filled half way up. ------------------------------- Do you want to support my channel?
