Computerized automation has been designed and installed on to two laboratory engine stands in a pilot project aimed at improving repeatability and efficiency of motor oil testing via ASTM MS sequence VB. Although testing experience is limited, practice of operating the stands automatically has been confirmed; compliance with test specifications has been tightened; and potentials for reducing operating and clerical support have been demonstrated. Impact on improving repeatability of engine deposits is still inconclusive. The computer-aided capabilities are proving highly useful in evaluating the adequacy of the test itself.
