my uncle did tests on this stuff. used it on a 100,000 mile Nissan motor. pulled the plugs and used a fiber optic camera to see the tops of the pistons. ran 2 tanks of 93 octane and BG 44K in both tanks. all the carbon was gone! you could see the circle imprints and #'s on top of the piston like new!
regular injector cleaner is just snake oil. BG can only be bought at dealers also.
Yes BG 44K is good stuff, it really cleared up a very rough running motor I had years ago, made a huge difference. I thought I was told it was only available to service shops, is that not the case?
