Power steering fluid

Most trucks seem to use either Dexron 3 or engine oil. What's your owner's manual recommend?

DOT 4 brake fluid is not petroleum based. Not compatible with oil.

 

Check your manual or call your manufacturers dealer of your choice. Give them your vin and they can tell you what to add.

 

We always used ATF, or that fancy store bought P/S oil,,,that's mostly ATF,,

 

Yeah atf, it has the right additives but just dyed to make it look special,
