Oil provides lubrication and cooling for the interior components in a vehicle's motor. After time and extended usage, oil becomes contaminated with worn particles from the engine's interior and becomes less effective at lubricating and cooling. It is important to know how to drain your 300m's oil so you can easily replace it with fresh, clean oil. The job requires a few basic tools and 15 to 30 minutes of your time.
