97 Integra GSR Coolant problems

[GQ Chris]

I did notice a big difference; I filled the tank up with 91 fuel as opposed to the 87 fuel I had in it for the past few weeks, and man what a difference!

I do notice that the car ran with a little more push with the 91 fuel. Never will I put in 87 again, I wouldn't want to risk detonation.

Good Job man. Better mileage as a lot more gas will be burnt and it'll be cleaner too.

Notice This from Car and Driver talking about knock sensors to prevent detonation:"According to Gottfried Schiller, director of powertrain engineering at Bosch, these block-mounted sensors—one or two of them on most engines and about the size of a quarter—work like tiny seismometers that measure vibration patterns throughout the block to identify knock in any cylinder. Relying on these sensors, the engine controller can keep each cylinder's spark timing advanced right to the hairy edge of knock, providing peak efficiency on any fuel and preventing the damage that knock can do to an engine."
