The Mazda MX-5 / Miata ND (EU) automatic transmission fluid capacity is 7.2 liters across all four listed engine configurations, covering both the SKYACTIV-G 1.5 and SKYACTIV-G 2.0 variants.
A 7.2-liter figure for an automatic transmission represents a full system fill, accounting for fluid held within the torque converter, valve body, and transmission case rather than a partial drain-and-fill service quantity.
The SKYACTIV-G 1.5 engine appears in two output variants — 96 kW for 2015-2018 and 97 kW from 2018 onward — yet both share the identical 7.2-liter automatic transmission fluid capacity.
The SKYACTIV-G 2.0 engine similarly spans two output ratings — 118 kW for 2015-2018 and 135 kW from 2018 onward — with no variation in the 7.2-liter automatic transmission fluid capacity between the two.
All four configurations carry a normal use condition designation, meaning the 7.2-liter capacity specification applies under standard operating conditions rather than a severe or first-change-only service scenario.
The consistency of the 7.2-liter capacity across both displacement variants and across the 2015-2018 model year span indicates a shared automatic transmission unit regardless of engine output differences within the ND generation EU specification.
