fleet trucks

It’s easier than ever to keep your fleet running smoothly for thousands of miles. If a vehicle has less than 50,000 miles on it today, chances are it still has 75 percent of its driving life ahead of it. That’s good news if you’re a company managing a fleet of vehicles. It wasn’t that long ago that hitting the 100,000-mile mark on the odometer was a major milestone. Today, vehicles are built to last. With the proper maintenance and attention, there’s no reason you shouldn’t expect to see that 50,000-mile reading on the odometer one day roll right past 200,000 and keep ongoing. Here at WORKING CLASS AUTO AND DIESEL, we're going to give you some tips on how to make that happen!
