When to Get an Oil Change
Routine oil changes are essential to keeping your fleet reliable and preventing costly downtime.
Most commercial trucks should have their oil changed every
5,000–7,500 miles, or sooner under heavy-duty use.
Here are a few signs it might be time to schedule your next service:
- Dark, thick, or gritty oil when checked on the dipstick
- Increased engine noise or knocking sounds
- Oil change or maintenance light illuminated on the dashboard
- Exhaust smoke or unusual odors from the engine
- Higher mileage or extended idle time since your last service
At Quirk Commercial, our certified technicians use OEM-approved fluids and filters to keep your fleet running strong, mile after mile.
