Vehicle care at Roberts
Keep dirt and water out of the fuel system.
Fuel filters trap contaminants in the fuel; water separators help remove water before it reaches sensitive fuel-system components. We offer diesel fuel filter and water separator service.
The right interval depends on your engine, model year and operating conditions. We follow your manufacturer’s schedule, including mileage, time, engine hours or dashboard reminders where specified.
Care matched to your diesel.
Include the water separator
Draining and filter replacement are different maintenance tasks. We service the separator as your manufacturer requires, including attention to water-in-fuel alerts.

Before you stop by
Your questions, answered.
Do you service water separators too?
Yes. Roberts offers diesel fuel filter and water separator service. We follow the requirements for your vehicle’s system.
How often should diesel fuel filters be replaced?
Follow the owner’s manual for your exact vehicle and engine. The interval may depend on mileage, time, engine hours and operating conditions. We can help you identify when service is due.
Is draining a separator the same as replacing a fuel filter?
No. Draining removes collected water; replacing a filter addresses the filter element. Each task follows the manufacturer’s instructions for your system.

Yes. Roberts services diesel trucks, including oil changes. Call or stop in to discuss your truck’s needs.
