Title: Not the best way to drain your oil
Review: Sediment and metal particles settle in the bottom of your drain pan and these kits can't siphon all that out. Most "quickie-lube" stations that pioneered this process have abandoned it because they were getting sued for damaging the engine.The right way to change your oil is to run your engine until hot and and drain from the bottom; that does a much better job of removing the sludge.
