BOYNTON BEACH, FL – Approximately 200 garbage trucks in the county fleet for Miami-Dade General Services Administration have gone more than three years without an oil change. The vehicles use the puraDYN bypass oil filtration system, according to puraDYN Filter Technologies Inc. Ronald Kleintop, fleet service manager, said that Miami-Dade GSA, whose heavy-duty vehicle life expectancy is approximately seven years, has been using the bypass oil filtration system on everything from landfill compactors to garbage trucks. “Before using the puraDYN system, annual costs associated with oil maintenance and purchase were approximately $54,200, or $162,600 over the past three years. With the puraDYN installed, we’re now averaging an annual cost of $5,400 per year for all 200 trucks. By using the puraDYN bypass system on these trucks, not only have we reduced oil costs by 90 percent, but oil and related maintenance costs will continue to decrease every year we add more vehicles equipped with the puraDYN system to the fleet,” according to Kleintop.
