They're a Canadian company that makes an oil fortifier and a fuel lubricant product. They are suppose to be good products, but I don't know if they've been tested on Wankels. I sent them an email and asked, but haven't gotten a response back yet. I know Pettit recommends something called Protek-R, so I was wondering if anyone has tried using the Pathfinder products with good (or bad) results?
