I’m using the FilterMAG on a spin-on transmission filter for my Dodge truck. With the FilterMAG, the trany filter does capture a lot of fine metal dust. I also have one of the FilterMAG’s differential magnets, which also captures a lot of metal dust. I’ve never put one on an engine oil filter, so I was curious what some of you thought. I change the oil once per year on my Dodge and Jeep Liberty, so I was thinking that the FilterMAG may keep the engine oil a bit cleaner. Based on all my UOA’s, I don’t see much metal debris in the engine.
Here’s a link for those who don’t have a clue what I’m talking about.
