I had put in a whole bottle of auto-rx in my 2002 accord which had about 41000, now im at 43200 still on the cleaning phase. The instructions said that I had to drain the 1500 later. I went completely passed that. Is it necessary to do the whole cleaning process all over again or continue to the rinse phase? After the rinse phase, I wasgoing to put a 3oz maintenance dose and 1 oz of LC together to ensure extreme cleanliness.
