Have any of you have experience with this product?

Looks pretty impressing and the site itself provides a lot good information about the octane number thing.
I for myself had no idea that there actually were test engines with variable compression ratio for determining the octane number...... very interesting.
As for standard octane boosting addtives, the Nulon from Australia seems to be the best but I could'nt find a distributor in the states...

Let me know what octane boost works the best for the car. Due to the f*cked up oil companies in So Cal, we're losing our 92 octane.

I haven't heard or tried the product you're referring to, but am interested in what you're finding out.

I'm not sure how to evaluate a given octane booster I buy.
Use butt dyno..? In their web site they claim pretty impressive increase in the octane number.. but...
Since it's very cheap and supposedly safe may be I'll just try one and see how it feels. I'll post the results if I find something significant.
