Full out, in this case, means hard accelleration on the on ramp to mix with traffic. Or foot to the floor to pass that motorhome going 30 in a 70 up the two lane road on the mountain pass. It's true. The engine will not knock on reg fuel but it's also true the same computer won't allow the engine to develop it's full potential either. It's your car and your choice.
Yup, that's all too true. Even under moderate acceleration, my '93 2.8 knocks on midgrade. For the extra 6 pennies, I use 93 octane and the knocking and pinging goes away when I'm trying to merge on a short ramp.
