A 1990 BMW 325i wasn't really driven a million miles, but it was on a treadmill for 4 straight years starting in 1989 to test what product?

Mobil undertook this historic test in 1989 with a brand-new BMW to see how well their new Mobil 1 synthetic oil stood up to constant use. The car was set to run at an equivalent of 85 mph for four years. The results were that the tolerance levels were the same as a new engine's, a huge win for Mobil.
