Whats up guys/ gals, been a while since I've posted on here but just a quick question (mostly to help me sleep better at night) I live on Long Island and as most everyone knows we're experiencing an absurd fuel crisis. My 2005 WRX is pro-tuned on 93 octane fuel which I always use however in this case it is impossible to find a station that has a supply of 93. I filled up with 87 this morning (I had a quarter a tank of 93 in my car already) and thought I might try to find some octane booster. That searched has proved difficult as well. Im just curious to know if this will be detrimental to my car at all. I baby the car (even more so during this fuel crisis to conserve gas) and I just want to know if mixing the 87 with the 93 will be at all detrimental to the car. Should be able to get premium fuel again next time I get gas, so I'll fill up again at about a half a tank to sort of balance it out. Just need words of assurance, I feel as though im being neglectful when I really had no other alternative. Thanks in advance to anyone willing to answer.
