Re: 100 Octane Question

There are four stations in my area that offer 100 octane at the pump. about $6 and change per gallon. Cheaper when compared to the 5 gallon pail price at a fuel store

Unless you race - there will probably be minimal gains to offset the higher costs.

The knock sensors in our cars will signal the ECU when pre-detonation occurs, the ECU in turn pulls the timing back to avoid knock. In theory, our engines should never knock, just lose power. (Unless you got really bad gasoline)

The higher the octane rating, the less likely the engine will knock (when performance driving) - and thus, the ECU won't pull timing - thus providing you maximum performance....
