I am buying a 2004 M3 with 99,000 miles. The owner said he replaced the diff fluid with Royal Purple fluid which does not have a friction modifier. He said he had it for a few months like that and before I purchased the car he would drain it and put in the OEM fluid?

Do you think this would have any negative effect or have destroyed anything?
