who uses which, and why? I'm looking at everything from the "top sider" from northern tool that kent from Mercedes source endorses.
LiquiVac Topsider Oil Changer | Oil Extractors| Northern Tool + Equipment
or the mighty vac units
Amazon.com: Astro Pneumatic 7342 Manual Fluid Extractor: Home Improvement
I'm even considering a 12 volt unit
Amazon.com : Shoreline Marine Oil Changer, 12 Volts : Oil Pump : Sports & Outdoors
thanks for the advice in advance, I don't have access to a compressor so im limited to the manual pump devices.
