Currently uses 1 fl. oz. of oil per 100 miles so I want to stay ahead of this problem. Car has 225,000 mi. Am planning on using B-12 poured in each cylinder over a 24 hour period , rotating engine by hand every 6 hours, then run on highway for 3 miles and change oil and filter. no visible tailpipe smoke at start up or when driving.chemtooler answered 3 years ago • Throttle Body Cleaner | Fuel Additives / Treatments1038 views1 answers0 votes
