So I am looking at the December 2010 Import Tuner magazine.They did a short review/fact or fiction test on this oil additive that RS-R has produced. RS-R advertised to the magazine that their oil additive improved a 350Z by 20whp, and apparently 40whp in a modded R32GTR, and improved fuel economy in a Prius by 4MPG.

The magazine tested this product on a '95 Civic DX, and an S2000. For the Civic, gains on dyno showed 2.8 whp and 1.9tq. For the S2000 gains were 8.1whp and 4.2 tq.

Apparently the product does not act as an oil thinner, it simply increases lubricity of engine oil. Does anyone have any experience with this product on our beloved Mitsu's? And if so, can we get a personal review of the product?
