Yup. I know i've used it just based on the name.I think the NOS ocatane booster might have been one of the best marketed products in a while!
Nope. It either takes effect right away or it doesn't at all. They're supposed to mix with the gas and raise the octane rating of the gas by a few points. Which according to the test didn't happen at all.Really it seems that based on the test nothing happens right away. In defence of the manunfacturers maybe its acumulative?
