FAQs

Can You Go 10,000 Miles With Synthetic Oil?

Many synthetic oils are designed to last up to 10,000 miles, but this depends on the engine, driving conditions, and load. Heavy-duty diesel engines may require more frequent oil changes. Always follow the manufacturer’s guidelines and consider oil analysis for accurate intervals.

What's The Difference Between Air Suspension and Leaf Spring Suspensions?

Air suspension uses air-filled bags to absorb road shock, offering a smoother and adjustable ride. Leaf spring suspension relies on stacked metal strips that flex under load. While leaf springs are durable and simple, air systems provide better comfort and ride control.

What Is The Best Way To Manage Fleet?

The best way to manage a fleet is by using fleet management software combined with scheduled maintenance tracking. This helps reduce downtime, track repairs, and manage fuel use efficiently. Proper training for drivers also plays a big role in minimizing wear and tear.

What Is A Full Maintenance Program?

A full maintenance program covers all scheduled services, inspections, and repairs for a set period or mileage. It includes preventive maintenance, wear-and-tear items, and often emergency repairs. These programs help avoid unexpected breakdowns and can simplify budgeting for fleet owners.

Why Do Trucks Break Down?

Trucks break down for many reasons, including poor maintenance, worn parts, and overloading. Common issues include engine problems, electrical faults, and suspension wear. Regular inspections and timely repairs are key to avoiding unexpected failures on the road.
