The filter is easy to access and get off, it’s the turning it sideways to remove it that is obscure. The plug makes it easy enough though. As for the drain plug, I’m moving to a 3 gallon bucket drain method; from what I’ve read this significantly reduces the splash effect.Have you considered a Valv-O-Max oil drain valve that you can connect a hose to?
And would slightly turning the filter to be sure it is not stuck, and then punching holes in it with a screwdriver to drain it, work for that application? For applications where this works you gots to make several deep holes and the bigger the better.
