How Often Do Diesel Trucks Need an Oil Change?

Most people choose a diesel-powered vehicle for two reasons, increased torque and inherent fuel economy. Diesel engines were once the sole domain of large commercial vehicles but both Chevrolet and GMC have changed the game, offering several diesel platforms – including SUVs. There are several fundamental differences between gasoline and diesel engines. However, one thing that remains unchanged is the necessity of oil changes. So, how often do diesel trucks need an oil change? It depends on a few factors. Let a Budds’ Chevy Service Technician walk you through a few things you might need to know.

Chevy & GMC Diesel Service Intervals

Every vehicle has a precise maintenance plan that was specifically developed by the automaker. Certain tasks must be performed after the vehicle is driven a certain number of kilometres. These intervals can change by model year, and depend on how a specific platform is configured. However, the following benchmarks are broadly applicable to many Chevy and GMC diesel trucks and SUVs.

  • Every 12,000 km: This is the common oil change interval for many diesel-powered vehicles. During an oil change appointment, a qualified service center will also check the oil filter and air filter, changing them if necessary. The vehicle’s tires should also be rotated at this point so they wear evenly. Trucks used for heavy towing or that work in dirty environments may need service before the 12,000-km mark.
  • Every 24,000 to 36,000 km: In addition to an oil change and tire inspection, service visits falling between 24,000 and 36,000 km are where the cabin air filters will be inspected and changed. Vehicles with four-wheel drive will get fresh transfer case fuel during this visit. Finally, windshield wipers are replaced as well.
  • Every 72,000 km: At this point, diesel vehicles owners are due to have their automatic transmission fluid and filter changed as well as the transfer case fluid on four-wheel-drive-equipped models.

Long Term Diesel Maintenance Intervals

Once a diesel truck has been driven for more than 100,000 km or 10 years, more intricate maintenance tasks need to be completed. After a decade owners will need to consider:

  • Replacing hood gas struts and tailgate dampeners
  • Inspect or replace glow plugs and wires
  • Drain and refill the entire coolant system
  • Inspect or replace accessory drive belts
