How long is power steering fluid good for?

The replacement interval for power steering fluid is usually recommended to be every 2 years or approximately 40,000 kilometres, with specific adjustments required based on fluid type and operating conditions. Mineral oil-based power steering fluid should be replaced every 3-4 years or 60,000 kilometres, while synthetic oil-based fluid can last 4-5 years or 80,000 kilometres. Regularly inspect the fluid's colour (normally transparent red) and odor; immediate replacement is required if it appears black or emits a burnt smell. Persistent low fluid levels in the steering system may indicate leakage, requiring prompt inspection and repair to prevent damage to the steering pump. For routine maintenance, always use the manufacturer-specified fluid to ensure proper lubrication and thermal stability, which are essential for maintaining steering responsiveness and prolonging system lifespan.
