What's the power steering fluid 2013 Nissan Altima type?

The recommended power steering fluid on the 2013 Nissan Altima is Genuine Nissan E-PSF or equivalent. If You don't want to use or You can't find that type of steering fluid, I can help name some products for You. Some of the products that You can use are Prestone Power Steering Fluid or Lubegard Synthetic Power Steering Fluid. The purpose of power steering fluid on a vehicle is to provide smooth steering when You turn Your wheels left and right. If You are having rough steering then I would look at the power steering reservoir to check if the level is too low. If it isn't then You might have issues with the power steering system.
