Professional Fleet Maintenance Services for Colorado’s Western Slope

At JW Diesel & Automotive, we specialize in keeping work trucks working, because we understand that every hour of downtime costs your business. When a vehicle’s off the road, productivity suffers, schedules slip, and revenue takes a hit. That’s why our fleet maintenance program is built around one core goal: keeping your business moving. Whether you manage pickups or a 20-truck operation, we deliver diesel-specific expertise, priority service, and reliable turnaround times you can count on.

What Counts as a Fleet? And Why Maintenance Matters?

If you’re managing two or more work vehicles under one business, you’re managing a fleet, and every vehicle in it plays a role in keeping your operation running smoothly. That might include:

  • Diesel pickups used for construction or contracting
  • Service vans for HVAC, plumbing, or mobile repair teams
  • Utility trucks for landscaping or electrical work
  • Light-duty work trucks used for deliveries or site visits

No matter the industry, fleet maintenance isn’t optional, it’s the foundation of reliability. Neglecting service can lead to breakdowns, safety issues, and lost time you can’t afford. At JW Diesel & Automotive, we take a proactive, tailored approach to fleet maintenance, helping you prevent surprises, reduce long-term costs, and keep your team on the road without the stress.

We Service Diesel and Gas Pickups

At JW Diesel & Automotive, we don’t just specialize in diesel. We also provide full maintenance and repair services for gas-powered fleet trucks. Whether your vehicles run on diesel or gasoline, our team has the tools and expertise to keep them running strong.
