What is “engine knock” and why does it matter?

“Knock” is an uncontrolled and explosive ignition of a hydrocarbon fuel, such as gasoline, in the combustion chamber. It causes a knocking or pinging sound, robs the engine of power and, left unchecked, causes serious engine damage. Fuel’s tendency to knock is measured by its octane number. Lower numbers denote greater knock tendency; higher numbers denote greater knock control. Knock may be eliminated with the appropriate octane number.

Must have for Friday Night Lights!

I use this in my 2012 Cadillac CTS-V, 6.2L, Supercharged Motor. Friday nights here are big for Street Racing. I'm a 64 y.o., gearhead, so when I pull up in the Caddy, I get some raised eyebrows. I always use, non-E-85, premium fuel and dump a bottle of the go-juice in the tank at the beginning of the evening. It is noticeable in the seat of the pants feel from the stock 556 h.p. LSA. We race everything from hopped up diesel trucks (yes, this IS Montana!), to 5.0 Mustangs to JDM projects. I'm not saying I beat the 'stangs all the time, but enough of the time to get some notice and respect.

Great boost in power

I extract ethenol from gas and use this to replenish the octane. Works wonders and much better than 105 or any other brand!
