Review: FloTool Spill Saver – A Must-Have for Mess-Free Fluid Fills! - I’ve been using the FloTool Spill Saver for several months, and it’s an absolute game-changer for anyone dealing with vehicle or equipment maintenance. This tool is fantastic for getting fluids to hard-to-reach fill points without the mess. The flexible spout and wide funnel design make it incredibly easy to pour oil, coolant, or other fluids into tight spots, like my car’s engine or lawnmower’s reservoir, without spilling a drop. The spill-saver lip is a genius feature, catching any drips and keeping my workspace clean. It’s sturdy, well-made, and feels durable enough to last for years, even with frequent use. The size is perfect—large enough to handle decent volumes but compact enough to store easily in my garage. Whether you’re a DIY mechanic or just doing routine maintenance, the FloTool Spill Saver takes the frustration out of pouring fluids into tricky spots. It’s affordable, practical, and works exactly as promised. I can’t recommend it enough for anyone looking to simplify fluid changes and keep things tidy!
Review: Great product - I have been using this to refill the DEF on a late model GMC truck for about two years now. Since General Motors decided to put the refill port in the most inconvenient and difficult place to service the DEF and after spilling this corrosive liquid every time I tried to refill, I finally found the almost perfect solution by using this refill tube. The 2.5 gallon DEF that you can purchase at many locations has a very flimsy spout and was very difficult to get started and pour into the refill port. This refill spout is sturdy and has a good solid shut-off feature. I securely hand tighten the spout on DEF container and lay it on it's side while inserting the tube in the refill port. Then just twist the shut off to start the flow. I also take my pocket knife and stab a hole in the top of the DEF container so it will vent and pour smoothly. After it's empty, I shut off the valve and remove the whole thing. It works great. I then rinse out the refill spout and put in a clean zip lock bag and stow under my rear seat, ready for use when needed. GM finally got smart and relocated the fill port to a more sane and sensible spot.
