What is the differential oil specification for the Prado?

[LaErin]

The Prado differential oil specification uses 85W-90 gear oil. Introduction to differential oil: Differential oil is a lubricant specifically designed for the rear differential lubrication of rear-wheel-drive vehicles, effectively providing protection for the differential. The functions of differential oil are twofold: first, it forms an oil film on the gear meshing surfaces to lubricate and reduce friction resistance, thereby extending the lifespan of components. Second, it serves a cooling function by flowing to dissipate heat generated by friction pairs, providing a cooling effect. Differential oil replacement interval: It is recommended to replace the differential oil every 40,000 kilometers. Vehicles requiring replacement should follow the replacement interval specified in their maintenance manual, taking into account their driving conditions.

I remember that the differential oil for the Prado generally uses SAE 80W or 75W-90 gear oil, with GL-5 specification being mandatory to prevent excessive gear wear. Anyone who drives this kind of off-road vehicle knows that the differential is the core component coordinating wheel rotation. If the wrong oil type is selected, such as using low-viscosity oil, the oil film will be too thin to protect the gears under high summer temperatures, and it will become too thick in winter, affecting power transmission. I recommend checking the owner’s manual—Toyota’s official recommendation might emphasize rust prevention and pressure resistance, especially since off-roading often involves rough terrain. If you’re changing the oil yourself, just buy a reliable brand like Mobil or Shell’s corresponding product. Don’t skimp on a few bucks—oil quality affects the vehicle’s lifespan. Regularly changing the oil every 40,000 km is crucial. Otherwise, issues like strange noises or oil leaks will lead to major repairs, compromising driving safety and wasting time and money. For peace of mind, have a professional shop check the oil condition during maintenance.
