I have 93 octane, ethanol free within 5 miles of my home. I am so fortunate !

Yes we do to, but many states have only 91, I even have 100 on tap at my local Sunoco that goes in the other cars

I have a choice between 91 pure gas(Shell or Exxon) or 93- 10% ethanol (BP).. I asked Chris Chessnoe (Callaway Chris)about which was better for my C6 Callaway SC606.. he said go with the higher octane with 10% ethanol over lower octane pure gas. I assume that true even moreso for the LT5..

Dealer replaced compressor today. They found oil was leaking from the pressure release switch on compressor as others have experienced in the C7 general forum. They installed another compressor and stated that the replacement appears to be redesigned. They thought it would take 7 hours but they got it done in just over 5. They also stated they had to reprogram the ecm for a misfire. I believe this is the service bulletin that talks about injector 7 hanging open on decel as was discussed in another post as TSB 18267 which was not a recall last time I checked in acdelco tds but perhaps that changed. I am not sure if this means no more flames at WOT or if its just for that hanging injector issue. They wrote it up as "18267 Flames from exhaust due to misfire-flames self extinguish" "9103859 reprogram and set up ecm per recall."
