Road tests with a fleet of 45 passenger vehicles and trucks on an unidentified commercial re-refined oil, a re-refined oil from the U.S. Department of Energy, Bartlesville Energy Research Center, and a virgin 10W-30 showed that over-all, the two re-refined oils performed at least as well as the virgin oil. The re-refined oils, particularly the commercial one, provided good engine deposit control, although vehicles using this preparation generally had higher oil consumption rates. The virgin oil has a marginally low base reserve (total base number) for a 13,000 km drain interval and showed a larger, and unacceptable, viscosity increase than the other oils. For the tests, partly sponsored by the Iowa Department of Transportation, oil samples from vehicles operated for two years at 6500, 13000, and 16,000 km oil drain intervals were analyzed and 12 representative engines were dismantled so that deposit ratings could be obtained. Used oil analyses and deposit ratings were not segregated according to driving conditions.
