Common questions about changing oils and fluids

Which automotive fluids need to be replaced?

All fluids and oils in a car need periodic replacement. This includes engine oil and transmission fluid, antifreeze (coolant), brake fluid, and power steering fluid. Windscreen washer fluid also needs to be topped up.

How often do I need to change oils and fluids in my car?

Oils and fluids should be replaced in strict accordance with the schedule prescribed by the car manufacturer. Engine oil needs to be changed on average every 10,000–15,000 km, but at least once a year. Manual transmission fluid has to be renewed every 80,000 km, and automatic transmission fluid every 60,000 km, unless otherwise specified in the car owner’s manual. Antifreeze retains its properties for 40,000–50,000 km or 4 years of operating the car. Power steering and brake fluids should be changed around every 60,000 km. In the case of faulty components and assemblies, these intervals may be reduced.

What causes high consumption of automotive oils and fluids?

High consumption of motor oil may be due to wear of the engine or loss of tightness of its gaskets. High consumption of transmission fluid could be due to a loose drain plug or oil dipstick, or warped seals and gaskets. If the pipes or the radiator are damaged, antifreeze can leak out. If you need to top up the brake fluid frequently, this indicates wear of the brake pads and brake caliper seals. Leaking power steering fluid is the result of loss of tightness of the steering rack.
