Did this UOA for fun. Car above has been in inside climate controlled storage for the last 3 years. Oil was last changed 6/12/14 and oil has 2500 miles on it. Car is started at least once a month and allowed to come up to temp. Oil is Valvoline VR-1 20W50 racing with a Mahn filter. I didn"t change it yet as I am going to put it back on the road this spring after a mini restoration of interior and paint. I've owned the car since October of 1993, 2nd owner and in the first 7 years I did a lot of BMWCCA driver schools, and its always been on VR-1 oil except for one change with Rotella 15W40.
