Drove a 1993 850 NA 5 cylinder for 30 years and 242,000 miles. No oil problems at all. Changed oil every 5k miles. There has been reported oil consumption problems with 2012 - 2016 5 cylinder using oil and low oil light not coming on, resulting in engine failure. A google search will show some of the issues. The problem was a new type of piston ring that allowed excessive consumption. Also, the dip stick was too long, or something, and it appeared to show OK oil level when it was low.
