I've used a LiquiVac for the last 2 years to change oil on almost every engine around the place, including my '97 E320, a Mazda Millenia, Ford F250, Kohler & B&S small engines on yard and farm equipment with no problems. The only thing it won't work well with are a Honda and a Yamaha ATVs because there are mechanicals between the oil fill and dipstick tube and the bottom of the sump that keep the suction tube from reaching bottom. I prefer the LiquiVac to the Topsider because it is a little easier to work around and empty.
