What are folks using for run-in oil these days?
Aside from new cars, which are a different situation, I haven't run in a new auto engine myself in ~30 years. I see many of the boutique manufacturers are offering them, and I expect my engine builder will recommend one but I like to get a wide pool of opinions. Engine is a 2.0L SOHC I4 M10 engine from a '74 BMW 2002. Eventually she will get my go-to oil for my Summer only vintage cars; M1 15w-50.
Thanks.
