No change. I never compromise on what I consider the best oil for my equipment. PUP for the MOPARs, BMW oil for the BMW, and Amsoil Small Engine Oil for the Generator. OEM filters. Vehicles get 1,000 mile initial change followed by 6 months or 5,000 mile max OCIs. Usually works out to about 3,000 miles or less. Gen gets annual or 12 hours of run time (exercise cycles) OCI unless it runs for a long period of time in an emergency (i.e., Irma).
