i just swapped a ls/vtec with b16 pistons into my integra. my gas tank is half full with 89 octane gas, and i was told to run 93 octane. what should i do about this?? should i fill the rest of it up with 94 octane and add some octane booster to get the octane level to about 91 or so?? please help me out.

 

syphon it out and then rip out the 94 and spluge it into the tank
