If you have a synthetic decal under the hood your car came with synthetic.
95 ti's for instance did not. If you have the dealer change the oil to synthetic they put the decal on by the info sticker.

I switched my 95 to synthetic 15W40 (Thats what BMW uses stock in the M42/M44 line) and so far so good. It definatley got quieter but thats pretty normal when I've put fresh oil in any engine.

Good Luck
Dave
