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?
No it will knock you need to run premium or you will damage the engine they wouldn't recommend it if didn't need it
it will not cause problems, just give a little less power when accelerating
