Enhanced wear protection, resists thermal degradation, evaporation and foaming. Provides continuous high pump performance, suitable for most power steering units. Light fluid prevents power loss 50% higher viscosity at high temperature and 1/5 the evaporation at high temperature Greater heat resistance helps prevent overflow. Helps prevent steering fade at high temperatures and unwieldy effort at low temperatures. Compatible with petroleum and synthetics. 1/4 of the oxidation of petroleum-based power steering fluids. Helps prevent leaks and squeaks. These fluids offer efficiency through a lower, more stable viscosity while offering maximum protection.
