Many markets have only E10
I don't believe that's the case with the Camaro ZL1. I found a copy of the Camaro High Performance Owners' Manual Supplement. It's on page 33 and it looks like anything up to E15 is approved. It is different in that the base model Camaros recommend at least 87, the higher performance models recommend at least 91 with 87 acceptable if 91 isn't available. That one recommends 93 but says 91 is the minimum acceptable AKI rating. I had to reassemble the order. It's really weird how it seemed out of order with a cut and paste.

Fuel
GM recommends the use of TOP TIER detergent gasoline to keep the engine cleaner and reduce engine deposits. See
www.toptiergas.com for a list of TOP TIER detergent gasoline marketers and applicable countries.
Do not use any fuel labeled E85 or FlexFuel. Do not use gasoline with
ethanol levels greater than 15% by volume.
Use premium unleaded gasoline meeting ASTM specification D4814
with a posted octane rating of 93.
If unavailable, unleaded gasoline with a posted octane rating of 91 may be used, but with reduced performance and fuel economy.
If the octane is less than 91, the engine could be damaged and the repairs would not be covered by the vehicle warranty. If heavy knocking is heard when using gasoline rated at 93 octane, the engine needs service.
Prohibited Fuels
Caution
Do not use fuels with any of the following conditions; doing so may damage the vehicle and void its warranty:
. For vehicles which are not FlexFuel, fuel labeled greater than 15% ethanol by volume, such as mid-level ethanol blends (16 - 50% ethanol), E85, or FlexFuel.
