Additional Notes

  • The Mazda MX-5 / Miata NC (EU) power steering system holds 1.2 liters across all four configurations covered in the specifications, spanning both the 1.8 and 2.0 engine variants from 2005-2015.
  • A 1.2-liter capacity for a hydraulic power steering reservoir is a relatively modest fill volume, consistent with the compact rack-and-pinion systems typically found in lightweight roadsters of this class.
  • The 1.8-liter variants from 2005-2011 and 2011-2015 share an identical service action described as a check at 20,000 km or 12 months under normal use conditions, whichever comes first.
  • A check interval, rather than a change interval, means the fluid level and condition are inspected at each service point without a mandatory full replacement being scheduled at that same interval.
  • The 2.0-liter variants from 2005-2011 and 2011-2015 are specified for a full fluid change at 40,000 km or 48 months under normal use conditions, a notably different service action compared to the 1.8-liter rows.
  • The 48-month time limit on the 2.0-liter change interval means that even with low annual mileage, the fluid replacement is due no later than four years from the previous service, regardless of distance traveled.
  • The divergence in service action between the 1.8 and 2.0 engine variants is present across both the 2005-2011 and 2011-2015 model year brackets, indicating the difference is tied to engine displacement rather than production period.
