I will claim no personal educational credentials to disagree with the linked article...But I run a Puradyn bypass filter, and this is an excerpt from their FAQ:
http://processfiltrationproducts.com/puraDYNFAQ.html
Q. HOW WILL THE puraDYN SYSTEM AFFECT OIL ADDITIVES CONTAINED IN NEW OIL?
A. Modern additives are added to oil to combat contaminants generated by the combustion process,
and to prevent excess wear under a “load.” When the puraDYN system is used, the contaminants
are continuously removed down to less then 1 micron, and therefore fewer additives are
depleted. A portion of additives that are depleted are replenished when make-up oil is added to
the engine and when additional make up oil is added at the time the puraDYN system filter
element is replaced at normal maintenance intervals. The balance of the additives that are
depleted are replenished as they are consumed by our patented filter, the standard filter element
containing time released additive pellets. Laboratory and field tests have fully established the fact
that the puraDYN system will not filter out or use up oil additives. The additives we use in our filter
are compatible with all additives in use today and will not upset the balance of the original
additive package. (See Ana Laboratories letter in ‘Customer Feedback’ section)
Er..I THINK they're telling me their filter is great, so...I think they're selling a filter.
Is there a prize?
