Changing engine oil can be messy, time consuming and there is no good way to dispose of old oil. The LiquiVac is a new user friendly and environmentally safe oil changing system. It is fast, convenient and eliminates mess and clean-up. The LiquiVac works by creating a powerful vacuum that draws the used oil out of the engine and into a holding tank for easy disposal to a recycling center. Simply insert the extraction hose into the dipstick tube, pump the handle 20 times, release the hose clamp and LiquiVac extracts the oil directly into its plastic holding tank. Works great for lawn and garden engines, go-karts, generators, ATVs and more. USA dimensions: 15-1/2 inches length x 8-3/4 inches width x 5 inches, tank size: 3/4 gallon, suction hose length 48 inches.

Your small engine's oil change has never been simpler, cleaner or faster. That’s right, no more oil spilling out all over your driveway or trying to tip your mower, snow thrower, generator, etc. over to access the drain plug. The LiquiVac oil extractor actually vacuums oil out through a hose into a portable reservoir.
From the heavy walled construction HDPE tank to the long lasting leather piston inside, you'll love the LiquiVac’s durable design. Sealable caps and pumps make it easy to transport the oil to your local recycling center.
Make oil changes a snap with LiquiVac
The LiquiVac oil change vacuum works on any kind of small engine including the following:
- Briggs & Stratton
- Toro
- Snapper
- Yardman
- Troy-Bilt
- Husqvarna
- Cub Cadet
- Bolens
- Honda
- Kubota
- Ariens
- Tecumseh
Small engine manufacturers recommend changing the oil in your small engine after every 25 hours of operation. For a new engine, you'll also need to change the oil after the first five hours of operation. New engines require this extra step to flush out small particles that accumulate naturally during the break-in period. Hours of use are just one factor in determining how often the oil should be changed; the amount of wear and tear is equally important. Just like the oil in a vehicle operated in extremely dirty or dusty conditions or at high speeds, the oil in a lawn mower or other small engine breaks down faster under tough conditions, such as wet grass, heavy dust, high temperatures and rough or hilly terrain.
Applications
Just think of all the small engines you own they all need regular oil changes to keep them running for a long life. Engines such as tillers, ATVs, snow throwers, push and rider mowers, Harleys, generators, power washers, 4- cycle power sports engines (outboards, personal water craft, go-karts, snow mobiles). The list goes on and on. Fortunately, the LiquiVac makes oil changes so easy, clean and fast.
Which Model of LiquiVac Is Right for You?
LiquiVac Small Engine Model
Small Engine Model
Small engines seem to be the most ignored engines that a consumer owns. This has occurred because there are consumers who have their car oil serviced at the quick lube places. And, have entirely forgotten that all the small engines in their garages need their oil changed too. 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, then engine 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. The LiquiVac Small Engine Model works by creating negative pressure, or vacuum power in the tank by pumping the tank handle. Each pump stroke takes air out of the tank creating a vacuum. Just 20 quick pump strokes creates vacuum power in the tank. This vacuum is powerful enough to extract used oil out through the dipstick/fill tube with the release of the suction hose clamp, in just 14 seconds. (Extraction time is based on the typical 4-cycle engine containing 1 quart of oil). With this kind of powerful performance and ease of use the LiquiVac Small Engine Model takes maintenance on 4-cycle engines very easy. Perfect for lawn mowers, lawn & garden tractors, tillers, generators, snow throwers, ATVs and outboard motors as well as.
LiquiVac Large Project/Engine Model
Large Project/Engine Model
It is called the Large Project/Engine Model for a reason. Its 8 quarts capacity is large enough to handle several oil changes at one time, without recycling/emptying it. For example you can change your boat engine and several small engines in one session. Because of this, many do-it-yourself people love to knock out their oil change projects in one fell swoop. Plus, they can do it fast, without the mess. 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.

I received this unit in April, but did not use it until Oct 2023. It did not work correctly. I followed the troubleshooting guide to resolve the issue. The steps did not correct the issue. So, I called the technical support number on the box and spoke to Matt. Within 5 minutes Matt had a replacement unit on the way. I received the new unit in two days, and this unit worked correctly for its purpose.Hopkins Mfg. is a company you can depend on, and have a good product and back it up.Bob

I just went back over my Amazon orders to check when I bought this pump. It was about 4.5 years ago so maybe I shouldn't complain. It was easy to use and the suction power was good at first, but now its zero, so I gave it 3 stars average kindof. I've used it a couple of times a year with no problem. Until now. It's not sealing any more and won't create a vacuum. I still have the instructions and they say to try putting a few drops of oil in the hole by the pump handle, to oil the internal leather parts, then work the pump handle a few time to distribute the oil, then let it soak for 12 = 24 hrs, then give it a try. Well its been several days and still doesn't work. I guess I'll take it apart and see what's inside. Got nothing to lose at this point. Since I paid over $40 for this I thought it would last longer. If I can't get it working I'll need to buy something similar but not this one. If it was like $20 then maybe I would.12/8/20 update: Ok I raised my rating from 3 stars to 4 because I took this thing apart and got it working again. If it's still working the next time I actually need to use it I'll give it the 5th star. I gently tapped the plastic end off the metal tube where the pump handle is. This allows the pump handle rod to come out and there's is a metal disk at the end of the rod with a softer outer ring (leather I guess) that should apparently create a seal against the inside of the metal tube. I wiped the leather off with a rag because it looked gritty with dirty oil, and put clean oil on it. Also cleaned the inside of the tube and put a little clean oil on the rubber gaskets as I put it back together. I pumped it up and this time it became progressively harder to pump. I stopped at about 15 pumps and opened the valve to definitely hear a good vacuum.

Bought this to change my motorcycle oil. Note that this unit is not really a "pump". You cock the pump handle a several times to create a partial vacuum in the tank then open a valve to suck out the liquid in theory.There was not enough suction power to pull much oil out of the pan. Not even close. I may have pulled out a 4 or 5 oz with each attempt. I suspect if it actually worked and the tank were to ever start filling, you would have less tank space to generate usable suction. It may work better with water or gasoline but is useless against motor oil.

I have the 3 qt model. It's a good quality product with lots of uses. Water in your boat's gas tank? No problem. Changing the fuel filter on a Ford diesel pickup? No more mess. Want to vacuum pack some stuff? Got it. Easily worth 40 bucks.My only complaint is the valve. It's a two-handed operation to open the valve when you're applying the vacuum. The valve turns counterclockwise. The lefty-loosey action unscrews the valve connection off of the tank, which then loses the vacuum you had pumped up from around the threads.Some tips and tricks:The tubing that comes with this bottle simply presses into the valve assembly. If you're not paying attention you can pull the hose out.Watch the liquid level in the tank. Don't get too ambitious with the level before you drain the bottle. Otherwise you're in for a surprise when you try to pump up the vacuum again. Whatever is in the bottle is now all over your hands, you, and everything else on that end of the bottle. Not great when it's gasoline.The vacuum is more effective if you open the valve up at least 3/4 of the way open. Trying to throttle with the vacuum valve doesn't work well and the liquid will tend to just sit in the hose. If you're only trying to pickup a small amount of fluid you don't need the bottle to be under a vacuum. Just pump the bottle while the hose is submerged, with the valve wide open. It will transfer the fluid to the bottle with each pump.For hard to reach areas you can zip-tie the free end of the hose to a stick. I use a good (Williams) telescoping magnetic pickup tool. This will let you get the water out of the bottom of a boat's gas tank, underneath the gas in the tank, without having to fight the hose. Ask me how I know. A metal clothes hanger would work as well.

This works great! Beware, though, that the plastic tube has an OUTSIDE diameter of 7/16". Unfortunately, the dip stick tube on my Guardian whole-house generator has a 7/16" INSIDE diameter, so I wasn't able to stick the vacuum line down into it. I won't be able to use it there until I add a narrower piece of hose to the end of the LiquiVac hose. But it did work well on my power washer and riding mower, both of which used to make for nasty and messy oil changes. Not anymore.The case is sturdy and easy to hold and maneuver. Note that the large tube enclosing the vacuum plunger can come loose of the case if you pull real hard on it. Be sure to unscrew the knob end before trying to pull on the knob to draw a vacuum. Otherwise. this is a great tool and I should have bought it sooner.

The pump works pretty good, but the hose is too big to fit down the dipstick. It was extremely frustrating. I had to buy couplers, new hoses, and various hardware to make this pump work. After my custom job, it did pump the oil very well. This may not be an issue for you but buyer beware. I was changing the oil in a sea doo jetski, which has a much bigger motor than a lawn mower or other small engines.
