I am not sure if this is the right section, but I would consider it preventative maintenance. I was hoping people could help my find where I can purchase 93 octane gas in the southern Maine area. I live in Brunswick. I plan on modding soon and I will need 93. People have mentioned specific gas companies, but I have had no luck finding it anywhere. If you know of a location, please let me know. For now, 91 will suffice, but I will need to locate some 93 soon.
If I cannot find 93, does anyone know if octane boosters (STP) are effective/appropriate?
Thanks in advance!
