What is a spinner type filter?
A8: A spinner filter works by spinning dirt out of the oil. The filter must be cleaned regularly to remove the build up of spun out debris. A spinner filter will normally only extend oil life by x3 times, because it is unable to remove water. Federal Express went from monthly to annual oil changes by using Filtakleen, a factor of x11 oil life extension. Some reports would suggest additives can be spun out of oil.
