what up guys...i just put my b16 into my crx...not fully wired yet...but....i have half a tank of gas regular octane (87) and its from the past march which is about 7 months old...what do i do to get rid of this gas or make it to like a 93 octane? and also wha is best gas to run with the jdm b16?

 

siphon as much as possible. Then fill it up with 93.

 

bah, use regular if its stock. no need to use high octane, unless you've got high compression.
