Monitoring of the Physical and Chemical Properties of a Gasoline Engine Oil during Its Usage

Journal of Analytical Methods in Chemistry, Volume 2012, Issue 1, 2012., 2012
Physicochemical properties of a mineral‐based gasoline engine oil have been monitored at 0, 500, 1000, 2000, 3500, 6000, 8500, and 11500 kilometer of operation. Tracing has been performed by inductively coupled plasma and some other techniques. At each series of measurements, the concentrations of twenty four elements as well as physical properties ...
