About Doc's Diesel
At Doc’s Diesel, our mission is simple: make diesel truck maintenance easy and affordable. Frustrated by overpriced dealership service and hard-to-find parts, we set out to create premium replacement filters that meet or exceed OEM standards—without the middleman.
We offer premium diesel filters, oils, and additives for Cummins, Powerstroke, Duramax, and EcoDiesel, which have been tested by leading labs for reliability and performance. Our lineup includes engine air filters, cabin air filters, fuel filters, oil filters, and more—engineered for trucks that work as hard as you do.
Proudly rooted in small-town Ohio, we’ve quickly grown into a trusted name serving all 50 states with fast shipping, expert customer service, and a seamless ordering experience. At Doc’s Diesel, you're not just buying filters—you’re joining the spirit of working hard, dreaming big, and family values.
