Hello Brian, How are you?
Since my post I had a look through the 'manual'. I had forgotten how bad it is.
It does not detail where the fill and drain plugs are, or how much oil is required.
Before I do anything I will post some pictures to confirm what I think the plugs.
I will speak to Warco before I order the new oil from them, but in the meantime, do you know how much oil I will need?
Ta.
