I wouldn't put ANY GM product in a Honda/Acura. I thought the old manuals used to say 5w-30 on the manuals(I could be wrong) I was reading that Honda MTF has additives to reduce friction and reduce noise/vibration. It's up to you I've used redline MTF too, It's ok. My Hondas all run Honda MTF. I'm with the idea that Honda Knows what they are talking about, why risk a problem?
