Slippery Pete Fluid Pump for Gallon Bottles and Wide Mouth Quart Bottles - Transfer Gear Oil, Transmission and Differential Fluid, Antifreeze with This 30cc Hand Pump

I picked up this Fluid Pump for gallon bottles and wide‑mouth quarts because I was done pretending I could pour fluids without creating a crime‑scene‑level mess. This pump delivers serious value for the money—no fancy gimmicks, just straightforward performance that saves time, product, and my sanity. The instructions were refreshingly clear (a rare win), and within minutes I had it connected and pumping like I actually knew what I was doing. The versatility is a huge plus: it fits multiple bottle types, switches easily, and doesn’t make me hunt down weird adapters. Compatibility is spot‑on, and the connectivity between the pump and bottles feels secure—no wobble, no guessing, no surprise leaks. Cleanup is simple too. A quick rinse and it’s ready for the next job, looking cleaner than I ever do after working in the garage. If you want an affordable, easy‑to‑use, mess‑free way to move fluids, this pump punches way above its price tag.

I needed to change the differential gear oil in my golf cart. This fluid pump worked perfectly for the Liqui Moly Gear Oil (GL4) SAE 85W-90 liter bottle. The white screw cap that was already on the pump fit the liter bottle perfectly. If you need to change out the cap, grasp the lower body of the pump and turn the pump head counter-clockwise to release the pump head. Be careful when removing the nut above the cap in that the spring is pretty stout and parts could go flying if you don't hold both ends firmly (maybe within a towel). When you're ready to pump, you need to prime the clear tube and fill it. Each stroke of the pump delivers 1 fluid ounce. It worked flawlessly for the 0.8 liters of gear oil that I needed (25 to 26 pumps). I highly recommend this fluid pump with the Liqui Moly gear oil.

Worked well with gear oil for my Subaru, need to work out how the pump connected to the Motul oil bottle but that was my fault. The hose is long enough to get into the fill ports, is well connected to the pump. It pumps a decent amount with each stroke and I am 100% satisfied with it. The multiple bottle neck adapotors worked on teh Motul bottle, something I have read was a issue with other pumps.
