Started my car up when I got home tonight and the slight ticking still existed and I was about to pull out of the garage it totally went away :). I proceeded to drive around about 20 miles and when I stopped to get gas I noticed that the ticking had started again. When I got home I am not sure if the noise was less or not but still not bearable to me. Any suggestions going forward? The oil and filter change currently has approximately 30 miles on it without any additives. Thanks,
