    2012-2013 CTS are flex-fuel capable?

    I was reading up on it and it seems that the 2012 and 2013 model year CTS uses the LFW engine, which is a flexible fuel version of the LF1, capable of running on E85, gasoline, or any mixture of the two. The LF1 was the engine that was used in the 2010-2011 model CTS.

    Does anyone know if this is true? I didn't see any information in the manual it just says the recommended fuel is 87 unleaded, and websites like fueleconomy.gov also support this. I also did not see a flexfuel badge on the car, which most flexfuel cars have.

    Does anyone know about this?

    From wiki
    The LFW is a flexible fuel version of the LF1, capable of running on E85, gasoline, or any mixture of the two. Output is identical to the LF1.
    Applications:
    Year(s) Model Power Torque
    2011–2012 Chevrolet Equinox 264 hp (197 kW; 268 PS) 222 ftlbf (301 Nm)
    2011–2012 GMC Terrain 264 hp (197 kW; 268 PS) 222 ftlbf (301 Nm)
    2012-2013 Cadillac CTS 270 hp (201 kW; 274 PS) @ 7000 rpm 223 lbft (302 Nm) @ 5700 rpm
    2012 Chevrolet Captiva Sport 264 hp (197 kW; 268 PS) 222 ftlbf (301 Nm)

    The operative word in the wiki entry is capable, which doesn't mean warranted for use.

    I looked at my window sticker, and there was nothing about flex. If I wanted to use e85, the first thing I would do is ask the dealer to tell me if it voided the warranty.

    It would also be nice if one of the Cadillac Corp people that follow posts on this website would request that info for us.
