The Petroleum Quality Institute of America (PQIA) recently purchased samples of passenger car motor oils in Washington D.C. To our disappointment, a significant number of the motor oils we observed and purchased on shelves at convenience stores in D.C. meet only API SA and SB Service Classifications. API SA is not suitable for use in gasoline engines built after 1930 and API SB is not suitable for use in gasoline engines built after 1951. These are obsolete specifications and oils that may cause harm in modern engines.
So one has to ask,why are obsolete motor oils that can cause harm to nearly all cars currently on the road, sold in stores right under the nose of our lawmakers in Washington, D.C.?
