Sure you might not get the full performance of the engine, but as stated elsewhere on the previous page, the car has a knock sensor. It's purpose is to detect knock and retard ignition timing if present. I wouldn't lose any sleep over it. On occasion, if i'm doing all interstate driving, i'll fill up half or 3/4 with 87, and alternate between the two during the trip.

Doesn't really work that way. You are most at risk from peak cylinder pressure. This is in the midrange at peak torque. So you can innocently hit the happy pedal while at 3K on the HWY or in town to pass someone and there you go with a 4000 RPM pull. You won't likely be able to hear any knock.

Yes, there is knock detection in just about every modern car which helps to shift the timing map entirely upon detection but why rely on that if you don't have to

I read your second post.

If Katie Upton walked by as I was getting Gas, i may have pushed the wrong button..

You are forgiven.. Drive mellow and no hard driving...You should be fine...Like her..

Reading this from the Nissan Asist TSB:

Find a heavy block (nissan part #PA2390)
Start vehicle.
Place block on gas pedal.
Allow vehicle to redline while in neutral until all gas is expended.

Have vehicle towed to nearest Nissan Dealership and let them know what you have just done.

Understandable. Was a passenger in a friends gorgeous 72 Vette once when a nice looking woman in short shorts and a tank top was walking on the side of the street (gotta admit, I was looking too). He ended up rear ending a US mail truck for rubber necking. Truck was fine, Vette's front end was no longer gorgeous

At least we laugh about it today, just not in front of our wives

Just to update the thread, I ran the car under 4k rpms with slow acceleration between gear changes and decided to fill up when my car had 1/3 of a tank left. Aside from the immediate improvement in engine idling and responsive acceleration, my car runs as good as new. Thanks for all the feedback
