Buying Guide

  • Compatibility: Check that the conditioner or additive is compatible with your vehicle’s power steering system and existing fluid type (petroleum or synthetic).
  • Conditioning vs. Leak Repair: Distinguish between products designed to condition and extend life (friction reduction, noise control) and those focused on sealing leaks. Some products blend features of both.
  • Noise Reduction: For vehicles with audible pump or rack sounds, look for conditioners explicitly claiming reduced noise or howl.
  • Application Method: Some items come as fluids to be poured into the reservoir, others as additives or repair-it formulas to mix during a fluid change. Follow manufacturer directions carefully.
  • Maintenance Strategy: Use conditioners as part of routine maintenance, not as a substitute for necessary repairs or fluid changes when systemic issues exist.
  • Vehicle Type: Consider domestic vs. import recommendations and gallon-sized versus bottle-sized packaging to match usage needs.
  • Safety and Solvent Claims: Prefer solvent-free or low-toxicity formulations when possible, and ensure proper handling as per label instructions.
