How do you quantify "it works" ? Engine runs smoother ? Better gas mileage ? Or open the valve cover before and after its use to verify that it does the cleaning ?
Smoother running, better mpgs offer some proof. There are a lot of guys here saying how much better their cars sounded and felt after adding it, a lot of people. We can't all be crazy!
I've had valve covers off many an engine over the years, not to see if MMO works but to replace gaskets. I've had a few pans down too, so I know it works. Can I prove it to you, sorry, no when I had these engines apart it was long before BITOG was even a thought. I looked into an oil fill hole on a friends car that was leaking via the VC years ago and suggested he add MMO and drive the car for the winter and we'd change the VC gasket in the spring when it got warm. We were both amazed at how clean that engine was 3000 miles later when we finally got around to replacing the VC gasket. Keep in mind if it is cleaning splash fed areas, it will do a bang up job at the bottom end of an engine.
Yes I agree with sprintman, why drop an oil pan for no reason? Or open up any part of engine today for no reason?
