well I guess if I had a cheap car/truck, I would give there filter a try... Ultimately if you keep oil clean from contaminates, it should last a good long time. Probably longer that most users change it out. If they have samples tested, and showing good results, Ok. If you look at a hydro system, unless a hose leaks you don't change it. Now I do understand that engine oil contaminates soot and carbon into the oil system that hydro systems don't. But as for wear abilities I'm speaking of. If the data says its good, data collected from these trucking industries is good data source, then maybe its something. Its just hard to believe, coming from a mentality to change your oil often 3-5k miles that oil can last more than 10k miles little lone 100K+ as the claims.
