Have you switched to regular gas to save money?

A lot of people think that a knock sensor will take care of that.

IMO they are incorrect -

When a knock is sensed - pre-ignition - changing the timing will NOT help - it is firing before ignition occurs.

The computer adds fuel to cool the offending cylinders

The result is poorer mileage.
