Summary:

A significant deterioration in low temperature pumpability properties (as measured by the mini-rotary viscometer; MRV) was observed in certain commercial-quality engine oils in a taxi field test program. A detailed investigation demonstrated that contamination by carry-over of the factory fill oil in combination with oil aging was the cause of the marked deterioration in low-temperature pumpability properties; no evidence of new oil incompatibility was observed using industry-standard test procedures. A subsequent investigation identified a number of commercial ILSAC GF-2 quality engine oils which also caused large MRV viscosity increases when added in concentrations as low as 1 wt% to used engine oils. A root-cause evaluation established that low concentrations of certain viscosity index improvers caused large MRV viscosity increases when added to used oils. Results from this investigation suggest that a new industry standard may be required to ensure used oil compatibility over a lubricant's normal drain interval
