Default Octane Question

Engine is 2014 5.7 Hemi

Dealer is telling me 87 no Ethanol is ok to run. Guys at work are saying 10% is fine but 87 will hurt the motor, stick with 89 and 10% Ethanol.

Needless to say, Im about as confused as I can be. For last 10 years its been the same fuel in the same truck 87w/ 10% Ethanol, but that was a 4.0L V6.

Thanks in advance
