Improvements in the Engine-Operating Sequence V Tests for MS Oils in Stop-and-Go Service


This paper describes the full-scale engine test techniques used in the “Engine-Operating Sequence V Test” and outlines improvements incorporated in 1962 for test control and oil consumption. A section of the paper is devoted to the effect of motor gasolines on varnish and sludge and their resulting rating levels. Data are also included on test repeatability and reproducibility with the designated reference fuels and reference oils.
