It had been suggested to me months ago that denim can make a pretty good filter for waste oils. Since I am trying to reduce my filter costs both in the obtainment system and under the hood I thought I would cut up some old jeans and try out the theory. I am really impressed with the quality of the oil I am getting with two layers of denim as a filter. It takes hours to get a few gallons of oil filtered, but I’ve come up with a extremely minimal setup that can be run in parallel.
If you haven’t check out “Holy Scrap Hot Springs” – I suggest getting a tall glass of iced tea and spending an hour skimming all the posts – it’s worth it, it makes me want to moved out there and join in.
