Oil Drain Pans And Funnels Available here. Changing your vehicle's oil at home is often one of the most accessible maintenance jobs, but you can make it even easier on yourself by getting the right oil drain pans and funnels. Not all funnels and pans are interchangeable, so make sure to get specific automotive tools if you want a clean and efficient lubrication change. Excess oil spills during the process cause a persistent mess, and the presence of oil often contributes to the premature failure of various sensors in your vehicle's computer system. These oil drain pans and funnels are designed to direct and capture oil as well as simplify your disposal and recycling processes during and after your oil changes.
