Anotherscott Scotty...I have two Acura 3.5 v6’s. One with 10.5/1 and one with 11/1 compression. Acura “recommends” premium. What do you consider “high” compression? Will 87 octane cause problems with the 287 and 310 HP engines?

it will not cause problems, just give a little less power when accelerating
