Twenty-five gallons of a hydrofinished virgin lubricating oil basestock was blended with additives into a 10W30 crankcase oil. After the engines had been pruged with a flush oil, 11 vehicles were charged with the blended virgin oil. Mileages ranging from 2000 to over 3000 miles of use were accumulated before the oil was drained, re-refined and recharged to the vehicles. This cycle was repeated until the oil had been re-refined three times. At each stage, detailed analyses and compound characterizations were performed on both the oil being recycled and on the same oil which was re-refined but never charged to vehicles. The data showed no significant change in the composition of the base oil, except for a minor buildup of additive base oil, which was expected.
