"We've been using the puraDYN Bypass Oil Filtration System in our fleet of 66 trucks since 1992. We're running Cummins, Mack and Caterpillar engines an average of 120,000 miles per year. We have trucks that have gone an amazing 616,000 miles without an oil change, reducing our oil waste by 23,000 quarts. We saved $1,700 per truck last year for a total of $115,000 by cleaning our oil, instead of changing it.

Also, by reducing oil waste we've had no disposal problems. The puraDYN  system has saved us a lot of time and money and in my business, that's what it's all about. So with puraDYN , we've been saving time, money and the environment. At Vulcan Chemicals, we spec the puraDYN  Bypass Oil Filtration System on 100% of our replacement trucks because we want to keep it clean."
