I just bought 4 qt of Motorcraft Super Duty 15w40 CJ4/CI4 Plus for my 285k miles 7afe Corolla, do you think it would be harmful for my engine beeing a diesel engine oil?
It doesnt carry an API S certification but I think it must work for gasoline engine. In the back it says that you shouldn´t use it in gasoline engined cars that have a cat and my corolla doesn´t have a cat (it used to).
I´m currently using a HDEO 15w40 CI4/SL so thats why I bought this HDEO Motorcraft, but I would like to know if I should worry before using it in 6 weeks when it will be time for a oil change.
