Castrol North America, Wayne, N.J., voluntarily agreed to discontinue ad claims of superior engine protection and "unique molecular bonding'' for its Syntec motor oil, said the National Advertising Division of the Council of Better Business Bureaus, New York. NAD found Castrol's ad claims weren't substantiated. Competitor Mobil Corp., Fairfax, Va., had filed the complaint. NAD said Hampel Stefanides, New York, is agency of record. Paul Waterman, marketing director at Castrol, declined comment.
