Re: Changing Oil - an easier way?
I have the West Marine version of the Moeller and I love it.
You only pump a few times at the beginning, to build the vacuum. Either way, you should run the engine for a few minutes to warm the oil. If you're pumping cold oil, it will take an eternity because it's very viscous.
