Recently when reviewing some equipment standards for a client, I noticed the requirement for a magnetic filter in the lube oil system. That made me think that a similar treatment of my Volt's lubrication system may pay off. With the high compression ratio of the Volt engine, any piston or ring wear might have serious consequences on performance. I've attached a graphic of the magnetic drain plug that is supposed to fit the Volt.
I have found two types of magnetic treatments for car engines. First is a small magnet on the end of the oil drain plug, and second is a belt-like magnet around the oil filter. I was wondering if anyone would care to comment about the usefulness of either type of magnet. Are the claims I've read about the usefulness of these plugs real? Can they serve to minimize engine wear? The drain plug is not very expensive; Amazon has one for the Volt for less than $10. The magnetic belt that fits around the oil filter seems to be a bit more pricey.
So should I buy a drain plug magnet or an oil filter magnet?
