LiquiVac Large Model


Which Model of LiquiVac is right for you?

Small Engine Model:
Small engines tend to be the most ignored engines that a consumer owns. There are not “quick lube” stations for these engines. Unfortunately this neglect can be very costly since these engines run very hard and in dusty conditions, which can lead to dirty, grimy oil and ultimately can lead to engine wear and breakdowns.

But, now there’s a simple, fast and clean way to change your lawn and garden equipment’s oil. It’s the LiquiVac Oil Changing System. With the LiquiVac oil changes are a snap. Perfect for lawn mowers, lawn & garden tractors, tillers, generators, snow throwers, ATVs and outboard motors as well as.

Large Project/Engine Model:
It is called the Large Project/Engine Model for a reason. Its 8 quart capacity can handle LARGE PROJECTS, such as doing multiple oil changes in one session. Its 8 quarts capacity is large enough to handle several oil changes at one time, without recycling/emptying it. Plus, the Large Project and Large Engine Model works great for LARGE ENGINES such as hard to change boats (inboards and outboards), trucks, and cars too. It is also very handy for to change transmission oil and hydraulic fluids too.
