This is misleadingÂ…. For exampleÂ….. Lets say an engine goes 100,000 miles before needing a rebuild using a Fram and its poor filtering ability.
The same engine may have went 130,000 miles with a quality filter.
So when you say "Never had a problem" its because noticing the slow destruction of bearings and machined surfaces is not as easy or as evident as catastrophic failure.
