Torrie can tune for 89. Not a big deal.
Where are you from? In Iowa, we have had 89 octane E-10 for like 20+ years, until recently. Now everything is blended and E-10 is 87. I understand that this is a decision from the Refiners and will ultimately affect everyone in US. Mason City IA Murphy used to have 89,91,93 E-10... Now no 89. Cedar Falls Murphy now is 87 & 93 E-10. Here in Naples, FL Costco has been 87 & 93 E-10 for as long as I can remember. On our recent trip from IA to FL, I never saw 89 one time. Used to be prevalent.
