I never really noticed differences in engine noise when changing oil brands, but the Green Elixir of Life has most definitely coxed some verbiage out of my little Honda Girl. When I enter the garage, she immediately tries to grab my attention by excitedly asking, "Hey Big Daddy, you gonna' take me for a ride?" I usually ignore her pleads for attention, and then she'll usually settle down and become quite unobtrusive as we cruise down the road. However, if she notices that were approaching an on ramp, she'll usually get quite vocal again. Yellin', "Spank me Daddy, please spank me hard." So...what's a feller to do? She wants to get spanked, so I spank her real good. Take up to redline through at least three of the gears. As we settle back down to a normal pace, I'll click on the cruise control for about 80. She'll then relax to a nice comforting purr. I guess that's the sound of afterglow, after a nice romp in the hey. So, yes, I guess you could say that the Green Elixir of Life has brought new meaning to my life, and to that of my loved ones.
