A detailed look at our specialized maintenance plan for light-duty commercial vehicles and fleets.
Severe duty conditions include: extreme temperatures (below -20°F or above 100°F), dusty or sandy environments, frequent short trips, stop-and-go city driving, towing or carrying heavy loads, extended idling periods, off-road operations, and high-altitude driving. Any combination of these factors typically requires adjusted maintenance intervals to prevent premature wear and unexpected failures.
Generally, reduce standard intervals by 25-50% depending on severity. For example, if normal oil changes are every 7,500 miles, severe duty may require changes every 3,750-5,000 miles. Air filters might need replacement at 7,500 miles instead of 15,000. The exact reduction depends on specific conditions: dusty environments require more frequent filter changes, while extreme temperatures affect fluid change intervals more significantly.
Most vulnerable components include: air and cabin filters (dust exposure), engine oil and coolant (temperature extremes), brake components (stop-and-go driving), transmission fluid (towing and heat), battery and charging system (extreme temperatures), belts and hoses (heat cycling), and suspension components (rough terrain). These systems require the most significant interval adjustments under severe duty conditions.
Monitor key metrics including: unplanned repair frequency, component failure rates, maintenance costs per mile, vehicle availability percentages, and driver complaints. Compare data before and after implementing adjustments. Track specific components like oil analysis results, filter condition at replacement, and brake wear patterns. Most fleets see measurable improvements within 6 months of implementing severe duty schedules.
Yes, the ROI typically exceeds 300% within the first year. While preventive maintenance costs increase by approximately $800 per vehicle annually, the savings from reduced breakdowns ($1,400), decreased downtime ($2,200), and fewer emergency repairs ($800) total $4,400 per vehicle. The 4-6 month payback period makes severe duty adjustments highly cost-effective for fleets operating in challenging conditions.
