Use whichever comes first, miles or time. Severe service (short trips, towing, dust, extreme heat or cold) shortens the safe interval by 25–50%.
🧠 Why This Interval Matters
Power steering pumps spin constantly and run hot. Old fluid loses viscosity, allows seal material to circulate as grit, and accelerates pump and rack wear. A pump replacement is $400–$800; a rack is $800–$1,500.
⚠ Signs You're Overdue
- Whining or groaning when turning, especially when cold
- Stiff or jerky steering at low speed
- Fluid in reservoir looks dark or has black flecks
- Foamy fluid (means air is being sucked in)
- Steering effort changes side-to-side
What happens if you skip itLow to medium. Won't strand you, but ignoring whining noises leads to pump failure.

❓ Frequently Asked Questions
Does my car have electric power steering?
Most cars built after 2012 use EPS, which has no fluid. Check the reservoir under the hood. No reservoir = electric.
Can I use ATF instead of PSF?
Some older vehicles spec ATF (Dexron). Check the owner's manual or the reservoir cap. Don't guess, wrong fluid kills seals.
Why is my fluid foamy?
Air is being drawn in, usually through a loose hose clamp, a low fluid level, or a failing pump seal. Fix the source before flushing.
Turkey-baster method vs full flush?
Turkey baster (suck out reservoir, refill, drive, repeat 3–4 times) replaces about 70% of the fluid and is plenty for preventive maintenance.
Will new fluid stop the whining?
Sometimes, if the cause is contaminated fluid or low level. If the pump is already worn, fresh fluid only buys time.
Does the system need bleeding?
Usually not, just run lock-to-lock with the engine running until air burps out and the level stabilizes.
