Hastings used to have a cotton wadding for a filtering media.
In the early to mid eighties they suffered a large law suit due to
the media breaking down and being released into the engine's
oiling system. Life seemed to stop for Hastings. They have now
re-engineered their product line, filters use a paper pleated media.
As I understand it, they are a middle of the road filter.
Not bad, but good for the price.
