DOC'S DIESEL CRANKCASE FILTERS - Doc’s Diesel Closed Crankcase Ventilation (CCV) Filters are designed to keep your engine running strong. By trapping harmful vapors and blow-by gases, they help reduce sludge buildup, oil breakdown, and engine wear. That means cleaner oil, fewer repairs, and a longer-lasting diesel engine. You’ll get better performance, lower maintenance costs, and a cleaner-running rig.
REPLACEMENT GUIDELINES - Above all recommendations, change according to your vehicle’s manufacturer's warranty. CCV Filters should be changed every 50,000-60,000 miles or 67,500 miles maximum.
