Why does Toyota use ATF for power steering fluid?
Toyota uses ATF (Automatic Transmission Fluid) for power steering fluid in some of their vehicles. The use of ATF in power steering systems is not unique to Toyota and is actually quite common in many vehicles. The main reason for this is that ATF has similar properties to power steering fluid and can effectively lubricate and protect the power steering system. Additionally, using ATF for power steering fluid allows for easier maintenance and reduces the need for stocking multiple types of fluids.
