I accendintly pushed the 87 ocatne(Regular) on the pump instead of 89. I had put less then 3 gallons in when I realized that I pished the wrong grade. Will this damage the engine any.

I've ran some 87 thru mine, i much prefer the 89 punch. It seems like it accelerates much more strong on the 89 octane.
