Not to mention that your reference to water injection is totally irrelevant. You are correct, water injection does suppress the onset of detonation, but not by the same method as an octane booster. Nice try. Now back to your original point in your first reply: I did read the SCC article you referenced and what you failed to point out was that only 1 (or possibly 2, its been a while since I read it) of numerous off-the-shelf brands of octane booster that were tested provided encouraging results that were near or at their labelled claims. Most of them failed the test. You left that part out conveniently and made a *blanket* statement that insinuates that they ALL *work* as advertised. Which is FALSE! The test that you hold so dear was clear on that. Some (or 1...2?) work, the rest do not.
