The old 380SL is finally going in for body and paint. I have 1800 miles on its current OCI. It goes into the body shop this week and will be there til about April of 2019. Should I change the oil now or later? Since the 5.0 MB engine was put in a few years ago, it has always gotten 15W40 conventional. I was thinking of putting in a 5W40 in the event this car is moved under its own power when its very cold. Part of me says leave whats in there now til it comes back next year.
