How much does it cost to maintain a heavy truck?

First of all, it depends on whether it is minor maintenance, medium-term maintenance or major maintenance. Minor maintenance includes changing oil, machine filter, air filter element, checking turbocharger, cooling system, brake drainage system, lighting system, brake, suspension and shock absorber system, tires and gearbox. A set of diesel vehicles is basically around 5000- 1W, and different models and prices do not need to clean up the carbon deposit every time. The throttle valve depends on the operating conditions.
