The udder way to change your oil. 3 in 1 oil change tool. Eliminate splashes and spills when removing drain plugs and oil filters, use as a funnel for your used oil. Keep your hands clean and protected from hot oil. Made out of thick flexible Nitrile Rubber to squeeze into the tightest spots and give you supreme grip on your filter for easy removal. A powerful magnet holds the udder securely on your oil filter regardless of how dirty it is for hands free operation. The drain kit allows you to allow oil to flow thru the udder for vehicles that discharge more oil than the udder can hold. The included combo plug allows you to cap off the drain kit when flow thru functionality is not required and also allows you to plug the included tube for drip free operation. ***Note: Compatible with spin on filters up to 3.125" in outer diameter. Works best with vertically mounted filters. Vehicles with large diameter drain plugs or high oil capacity may have higher flow of oil and can overwhelm the drain kit when using it as a drain plug catch/spill guard. For these vehicles we recommend removing the drain kit for higher flow. Oil and engine components are hot and can cause burns, please use protective equipment and refer to your vehicles owners manual for safety information.
