I checked out their website and tech data and found it to be reasonable. Their basic claim to fame is that their refined form of calcium carbonate (yes, like TUMS ) is effective at filling asperities in bearings and cylinders etc and reducing friction. There are also other additives that are allegedly effective at keeping sludge build-up down and increasing oil life.

If it does what they say it would be effective IMO. What's lacking though is a statiscal data base on dyno and/or road testing engines with comprehensive tribological analyses before, during, and after application of the stuff. Of course that kind of testing costs plenty of money.

You guys use it and tell me how you like it .....
