Objective

To improve filtration by the removal of ferrous particles out of the oil system of a gasoline engine with a magnetic filtration system (Halex Coil).  An oil sample was taken at end of an oil cycle.  In this case, oil is changed every 300 hr.  After the initial sample was taken, the Halex Coil was installed.  At the next 300 hr, a second oil sample was taken.  This was a dynamic test.
