Gulf Coast oil bypass filter on a 2005 Freightliner Columbia with a 14 liter Detroit engine. I have read several posts from way back when, on different forums, that paper towel rolls (Bounty, specifically) can be used as the filter element in a Gulf Coast Oil Bypass Filter (GCF). I even ran across a city council report out of somewhere in VA that had conducted a study on using different bypass filters for their firetrucks, etc, where they quoted Mr. Simms, the owner of GCF, as having said that paper towels could be used. My question is this: Is there anyone out there that is actually buying Bounty paper towels and using them instead of the expensive elements sold by GCF? If so, how are you doing it? Are you just inserting the rolls straight from the grocery store? Are you buying cheap ladies stockings and cutting them to make a sleeve for the towels to go in, and if so, is the oil hot enough to melt them or have a chemical reaction with the nylon and dissolve them? Folks on forums say it "can" be done, but is it actually BEING done? Thanks in advance.
