It's the same basic scam all the oil additive hucksters use. First runs are done without the additive and the engine cold. You shut the engine down, install the additive, and run the engine again until it's warmer and the oil has thinned out. Now you do a couple of pulls and get higher numbers. It'd do the same thing if you poured half a cup of peanut oil in the engine instead of the additive.
I'd have to agree with 'dk' here. They say that dyno's don't lie, well, a dyno operator can finagle numbers through a variety of testing procedure, so even though the dyno doesn't lie, the operator may be.
How ironic, they just profiled this very product on Horsepower TV this morning. Test was done on a stock Dodge Charger SRT. The test revealed a 9 HP increase after using the product. Wow, I can't believe the power! (sarcasm).
On another note, I just finished reading an article about oil additives stating that they are a total waste of money that none of the car manufacturers recommend adding. At best, all they'll do is help drain your wallet, at worst, they can foul up a perfectly good engine.
I would never trust this stuff. Remember Slick 50? That company was investigated for fraud and was ordered to pull all advertising making those outrageous claims. You can still see it in stores, but you don't see the ads anymore. I wonder how many wallets were drained from that stuff!
I would doubt it works. THe only time I would believe something like this would work if it is coming from an extremely well known racing company or something. Someone unknown, I wouldnt trust at all. That is my opinion. SCAM
