I use Mobil-1 oils,gear oils,and ATF in my 4 cars and 2 trucks. I want to change out the power steering fluid in my Nissan Titan and Frontier. Manual says Nissan power steering fluid or Dexron III. Mobil-1 ATF meets Dexron III specs. I think I am going to try it. Anybody else using this in a Nissan power steering unit?
