Types of Oil Within Your Volkswagen Car

Ever wonder, “What is differential oil?” or think about what other types of oil are within your car, besides engine oil? North Penn Volkswagen takes a close look at some lubricants you might not have heard of but which play an important role in ensuring a smooth ride.

What Is Differential Oil?

Also known as gear oil, differential oil lubricates and cools the gears in your car’s differential and, on all-wheel-drive models, the transfer case. For example, in a new Volkswagen SUV, it reduces the heat and friction between meshing gears and helps protect them from wear and corrosion.

What Is Transmission Fluid?

If engine oil and differential oil are numbers one and two in terms of importance, then transmission fluid is #3. Not only does it lubricate the transmission’s valves, clutches, and gears, but it also transmits the hydraulic pressure required for shifting from one gear to the next.

What Is Power Steering Fluid?

Hydraulic power steering systems use a dedicated fluid to carry pressure from the steering pump to the rack, making the wheel easier to turn. Many newer cars, including the Volkswagen Atlas and Volkswagen Tiguan, use electric power steering instead, so there’s no power steering fluid to service. On older vehicles with hydraulic steering, the fluid still matters and is worth checking at service time.

What Is Compressor Oil?

Compressor oil, or refrigerant oil, is a key lubricant in your vehicle’s air conditioning system. It circulates with the refrigerant to lubricate the compressor and help with sealing and cooling. By reducing friction and heat in the compressor, it helps keep the system from overheating.

What Is Chassis Grease?

Here’s another lubricant that isn’t top-of-mind for most drivers. Chassis grease reduces friction and wear in components like ball joints and other steering and suspension joints. Many modern vehicles use sealed, factory-lubricated joints that don’t need regular greasing, so our team at the Colmar, PA Volkswagen dealership inspects them for wear and damage instead.
