According to that white sheet you can. The computer recognizes the different fuel and adjusts for it.

Thanks for that link. There are certainly some impressive features. The E85 conflict is a bit disturbing, though this slick sheet implies there is no problem with burning it.

Sure would like some "official" clarification from GM/Chevrolet.

I have a 2012 2LS an right on the window sticker in bold black letters it said E85MAX and it is in the owners manual that E85 is fine to run as a fuel. The conflict comes from owners of a 2010 or 2011 which can't run E85 so assume no one can and keep spreading this misinformation. I run it and get about 2 mpg less than E10 89 octane with no noticeable difference in drive-ability or power. I lose a little mileage but the car the Camaro replaced got 14 mpg so I'm still ahead.

My manual says its not compatible 87 and higher only???? Anyone else check your manuals.
Read manual states the following.
"the eighth digit of the VIN shows the code letter or number that Identifies the vehicles engine.
RECOMMENDED FUEL: If the vehicle has a 3.6L V6 engine VIN CODE D, use regular unleaded gasoline with a posted octane rating of 87 or higher.

so mine is in a 3 so can we put E85 in these or not?

GVMV · 05-31-2012, 11:36 AM

I just got mine a month ago, and manuel doesn't say anything about being able to run E85. The person who said it says it in there owners manual can you scan it and post it up.

Camaro588 · 05-31-2012, 11:45 AM

it doesnt say you cant either

Fish-man · 05-31-2012, 11:54 AM

LFX goes into a lot of cars... and i beleive that the fuel system would also need to be compatible. Perhaps the Camaro doesn't have the fuel system to support, and thats why the manual doesn't state E85...

Camaro588 · 05-31-2012, 12:02 PM

The only thing the manual states is you cant put in e85 if the vehicle is not designed for it. if you read my earlier post its also states that if the vin code is D you cant. LFX motors are VIN CODE 3...so im assuming you can.

KMPrenger · 05-31-2012, 12:51 PM

It depends very much on the tune. The LFX CAN run E85 in other vehicles, but not openly advertised as such on the 2012 Camaro.

That could mean that the programming to run E85 is included in the other vehicles but perhaps not on the Camaro.

Could the camaro run it if it is tuned for it? Of course. E85 has been ran in several LLT V6s and proven to make great power at a cost in fuel mileage. I'm certain you could tune the LFX to do the very same thing.

Is E85 supposed to be used in a stock 2012 V6? Not sure about that.

I'm not "assuming" anything. After spending $150 to get the fuel system on my lawn tractor repaired becasuse of 3 years of using 10% ethanol gas... I'm staying away from E85 until someone can officially tell me my car can handle it without causing damage.

And that, I believe, is the question at hand.

CPT_Hoolie · 05-31-2012, 01:04 PM

I called the Chevrolet Customer Assistance Center (800-222-1020), and the answer was...

NO

the stock 2012 Camaro can NOT use E85.
