Additional Notes

  • The Mazda RX-8 SE (EU) automatic transmission fluid capacity differs between the two available power outputs, with the 141 kW variant requiring 8.7 liters and the 158 kW variant requiring 8.0 liters.
  • The 8.7-liter figure for the 141 kW automatic transmission represents a notably higher fill volume than the 8.0 liters specified for the 158 kW unit, a difference of 0.7 liters between the two configurations.
  • Both power variants share an identical service check interval of 20,000 km or 12 months, whichever comes first, under normal use conditions.
  • The 141 kW automatic transmission specification applies across a 2003-2011 model year span, while the 158 kW specification covers a narrower 2006-2011 range.
  • A 20,000 km or 12-month check interval, as specified for both variants under normal use, is a monitoring interval rather than a full fluid replacement schedule, meaning the fluid level and condition are assessed at that point rather than automatically replaced.
