Re: Changing Oil -- Universal 5424
I changed the oil on my 5424 last month, and it definitely took about 5.6 quarts. However, on my engine, someone has attached a pipe to the sump drain plug, with a brass fitting on the end. I don't know if this pipe was original equipment, or an accessory.
Anyway, what I do is warm up the oil and then insert the plastic pipe for my electric oil change pump, right up the pipe attached to the sump plug. This works great. Still, my little electric pump takes about 10 minutes to drain all the oil.
It seems the problem is that your pipe is not going all the way to the bottom of the sump (obviously!)
