Reply to "Best Oil Filter"

Hi Jeff,

we use the puroilater on our Subaru Forester GT, the 5 ┬Ám is real and works,
we combine with a washable foam filter on the air induction and reduced the contamination levels in the negine oil from an ISO 21/19 back to an ISO 16/13-17/14 which is very acceptable for a rice burner with a hair dryer on it, (Turbo Charged 4 valves per cyl twin overhead cam very sensitive to dirt motor.
Ou lab has completed extensive WDA reports and images on these results and tried several filters before settling on the puroilater so we think good filter and works well
