During your truck driver training program, you will receive instruction on how to maintain a commercial truck. Truck driving schools offer courses that cover pre-trip inspections, basic maintenance, and more. One of the most important steps of caring for your truck is changing the oil. During your oil changes, you will need to choose between regular and synthetic motor oil. While synthetic motor oil is designed to last longer, regular motor oil is a budget friendly choice that is appropriate for many engines. To determine the best oil for your truck, you can consult the owner’s manual. When you graduate from truck driving school, your CDL training will have prepared you to care for your truck during all of your drives. By enrolling in a truck diver training school near Portland , you will be ready to start your journey as a commercial truck driver.
