An oil change technician is responsible for vehicle maintenance and performing light automobile repairs like oil changes and tire rotations. Some employers list these jobs as “Oil Technician” or “Lube Technician.” Your responsibilities in any of these positions include evaluating what a car needs and mastering the equipment needed to repair vehicles. Other duties include assessing a car’s mechanical functionality. You also perform preventative maintenance, including checking and refilling vehicle fluids and replacing filters, lights, and wipers. You must maintain a clean and safe work environment, as working with cars can often be a dirty job.
