How often should I change my oil in my medium and heavy-duty vehicle?
Oil change intervals for medium and heavy-duty vehicles are based on a number of factors. In addition to the recommendations in the owner’s manual ,we look at the type of use the vehicle is used for (long trips vs. short ones with lots of stopping and starting), how often the vehicle is driven (does it sit for long periods of time), and the kind of driving (city vs. open highways). We look at these factors for each individual vehicle in order to create a maintenance schedule.
When should I have my air conditioning serviced?
There is no recommended interval for having you air conditioner serviced, but you’ll know it’s time if the unit is blowing hot air. Of course, if you’re planning on taking a long trip you may want to have it checked before you leave, especially if you’ll be crossing the desert.
Does my air filter need changing?
Changing air and fuel filters is an important part of regular diesel engine maintenance – even more so than a gasoline engine. Your owner’s manual will list the recommended intervals for each. If you frequently drive or operate any vehicle in dusty conditions, you will probably want to do it more often.
