Can you use transmission fluid as a substitute for power steering fluid? Yes, you can use transmission fluid in place of a power steering fluid. But, make sure you check the car manufacturer’s recommendations before using the ATF as a substitute. Automatic transmission fluids come with friction modifiers.
Q. Can DOT 3 brake fluid be used as power steering fluid?
Can brake fluid be used for power steering? The answer is a resounding no. If you used brake fluid in your power steering system, it would cause significant damage.
Q. Can DOT 3 go in power steering?
Yes they have few resemblance other than being liquid. Most brake fluid (DOT 3) is glycol based and system seals are manufactured compatible with glycol based fluid. Power Steering however is usually petroleum based and its seals and tubing are manufactured to function with petroleum base fluids.
Q. Is transmission fluid and power steering fluid the same?
Is power steering fluid the same as transmission fluid? Both of them are hydraulic fluids. But, the biggest difference is ATF contains detergents and friction modifiers. The detergents filter grease and dirt that may go into the power steering system and damage the pump and steering rack’s hydraulic valves.
Q. Will dot 3 eat paint?
All DOT 3, DOT 4 and DOT 5.1 fluids — the numbers refer to U.S. Department of Transportation specifications — are conventional glycol/ester-based hydraulic fluids, meaning they can and will damage paint if spilled on automotive bodywork.

Q. Can I mix brands of DOT 3 brake fluid?
Brands do not matter. Brake fluid is rather simple in design. Dot 3,4, and 5.1 can all be mixed. The difference is, as the number increases, so does the boiling point of the fluid.
Q. Is all DOT 4 fluid the same?
DOT 4. DOT 4 is beginning to be used more widely in by vehicle manufacturers, but is used mostly by European car manufacturers currently. Although there are different types of DOT 4 brake fluid, it has a higher boiling point than DOT 3. DOT 4 is twice the cost of DOT 3 and for most, there’s little benefit to switching.
