Following manufacturer-recommended service is an important part of maintaining your heavy duty truck.
At TEC Equipment, we’re here to support your heavy duty truck service needs at every level. We’re Mack and Volvo experts, so we know those trucks inside and out. When your truck is due for maintenance, we’ll let you know so you can stay on top of your truck’s maintenance needs.
Routine maintenance is an important piece of owning any piece of equipment, from wrenches up to massive backhoes and bulldozers. Preventative maintenance (following your manufacturer’s recommended timeline) ensures that your equipment will last as long as you need it to. Preventative maintenance is about taking care of your equipment on its timeline, not your own.
Maintenance isn’t a one-size-fits-all though. Needs vary by usage. Is your usage normal to heavy duty? Maintenance is less frequent. Is your usage severe duty? Then you need to take more time for truck service.
The most frequent maintenance your truck will need is an oil change and a battery service. Regardless of usage, you should have your battery serviced every six months. Your battery takes a beating, and you don’t need it failing you when you stop for fuel.
An oil change depends on usage. In normal to heavy duty usage, you should get an oil change every 40,000 miles or every 1,300 hours. In severe duty situations, you should change your oil every 35,000 miles or every 825 hours.
Check out the table below for Mack and Volvo’s recommended truck service intervals. Drivers know their trucks better than anyone, so it may be advisable to schedule these earlier than recommended so you can stay on the road.
