Maintenance Intervals by Vehicle Class
Oil, brake, and tire schedules differ dramatically by vehicle class. Get the right intervals for light, medium, and heavy-duty fleet vehicles.
Key Facts
- Light-duty gas: oil every 5K-7.5K mi; heavy diesel: 15K-25K mi
- DOT tire minimum: 4/32" steer, 2/32" drive — pull earlier for safety
- Severe duty cuts all intervals by 25-50%
