What gas octane do you use?
#106
The only benefit to a high octane fuel is that it allows an engine to run at a higher temperature and with a higher compression ratio without pinging. Higher octane fuel does not provide more energy, more power, better mileage, more torque, burn cleaner, clean your engine, and is not better for the environment.
If you run too high of an octane, you car will not be able to properly burn it. It will lead to increased carbon deposits and can foul your plugs and clog your catalytic converters. (especially the fools that run leaded race fuel).

Also the owner manuals for non revup sedans suggests 87 Octane.

That fact alone should increase his quarter-mile time by nearly half a second...

Why? Many people run regular unleaded with no issue. Unless you experience knocking, there is no difference. Most new cars, including the G35 have knock sensors that automatically retard timing a couple degrees if any engine knock is detected. If this happens, you may loose a fraction of performance, but it would not be detrimental to the car. You run more risk of damage to the car running higher octane than recommended than you do lower.

The sedan drivers typically choose Premium at my gas station. The drivers I was referring to were Coupe owners.

My mechanic, a close family friend, begged me to not even consider anything lower than 91 for my G. He told me of the horror stories of discovering the majority of G owners engine problems were from lower octane fuel. Choosing premium fuel is only 5-8 bucks more for each fuel up, that small toll is worth saving myself a costly headache in the future.
