Gas problem
All you need to do is pour a can of octane booster in the tank which you already did. For the majority of the rest of the tank don't go WOT or drive at high rpms, just drive normally. Personally I'd wait until about an 1/8th of a tank is left and then fill up with 93 and you'd be good to go.
Same thing happened to me. I bought my car from the dealer and they advised me they had accidentally filled up my car with 87. I had a 200mile drive back home. On the way home I stopped at a gas station and threw a bottle of booster in it and just drove normally.
Also I put Octane booster in and it didn't help. I later found out through research that you don't even gain a full octane value that you see on the pump. If its is advertised to gain 10 more octane values you get like .5. Also adding another one would only increase it to .75. So really you would be running 87.5 with one bottle and 87.75 with two.
If your really worried fill it up when it gets to half then again at half. This will dilute it enough. You should be fine and have no problems.

you'll be better off topping the tank off several times with 93 to boost the octane as much as possible...rather than running it down to almost empty.
adding 5gal of 93 to 10gal of 87 yields 89 octane.
