[QUOTE="ddgermann, post: 123706, member: 3537"] Just in case you guys with 17 and 18 Z06s are like me and didn't bother reading the manual buying a new Z06. I traded my 15 Z06 for a new 17 and since it was the same color I didn't bother doing much but skim the owners manual for Z07 specific information. Rick you probably run premium already but will want to consider this now as well with your new supercharger getting installed. Be aware the octane requirements are higher in the 17/18 Z06s. Here's the 15/16 Z06 manual. LT4 calls for 91 or higher. [ATTACH=full]14246[/ATTACH] Here is the 17 Z06 manual. LT4 calls for 93 and minimum 91 with reduced performance. (We were on 91 last October Jeffy) [ATTACH=full]14245[/ATTACH] Quite a bit written about the 17/18 Z06 being tuned for 100 octane from the factory as part of the overheating problem solution from GM. This tune is allegedly available for the 15 and 16 Z06 at the dealers as well, but will increase the recommended octane to 93. Not sure about this as I haven't asked the dealer. From what I could find via Google in Edmonton/St. Albert the max octane rating for ethanol free fuel is 91. Available at Hughes, COSTCO, Superstore and Shell. So 94 octane from Husky = 10% ethanol in Alberta. It says my car is ok to 15% and I have no choice to run on the recommended octane if I want the performance. We've had this discussion a few times here but as 91 was recommended for my car at the time, I just glossed it over. Today I checked.... [/QUOTE]
