Has anybody out there noticed a tremendous increase in power(quicker response & acceleration) after reaching the 9,000 - 10,000+ miles point? I can't believe it.. earlier I was using oil at about 1 quart every 600 miles- - -lately its every 800-1000 miles.. I've also found looser handling, much quicker engine response, and a deeper engine rumble than before.. Anybody have similar observations ??.. This car is a dream - - and its just getting better !!
