Oil change in a generator
I have a 2017 Thor Synergy Diesel with a 3.2 KW Cummins Onan diesel generator, Model HDZAA. Has anyone changed the oil in this generator and if so, do you know the size wrench needed for the oil drain valve cap. To open the drain cap, do you push the wrench towards the unit, or do you pull the wrench away from the generator and towards yourself. My drain valve seems very tight and I cannot remove it. Any help will certainly be appreciated. Thank you!
