Has anyone heard of this stuff. I searched the net but I didn't find anything that seemed very credible. To me, credible is defined as a favorable report of a product by someone NOT trying to sell it. I know that it's made in Colorado Springs and used to be called RK44. A salesman said that during testing, they ran a car with the RK additive, then drained the oil and raced the car up Pikes Peak with no oil...and it made it to the top. I'm throwing the BS flag on that one. Any other opinions in here?
