Most of them cost less than twenty dollars. And if you drive a modern BMW, most of them will do very little for the part of your engine that actually needs cleaning. So we took seven of the fuel system cleaners and treatments BMW owners buy most often and put every one of them up against the same standard: is this bottle actually built to clean a direct-injection BMW injector, or is it mostly just expensive-smelling gasoline? Only three made the cut. And one of the ones that didn't is probably sitting on a shelf in your garage right now. Stay to the end, because I'm going to show you the one problem no bottle on that wall can fix on a BMW, and the one question to ask before anyone charges you hundreds of dollars to "fix" it for you.
