Additional Notes

  • All six diesel configurations listed for the Renault Mégane IV carry a 16-liter AdBlue tank capacity, which is a relatively generous reservoir size for a compact car and reduces the frequency of top-ups between scheduled service visits.
  • The 16-liter figure represents a service fill capacity rather than a dry or overhaul fill, meaning it reflects the usable volume available to the selective catalytic reduction system during normal operation.
  • AdBlue, also known as Diesel Exhaust Fluid, is an aqueous urea solution injected into the exhaust stream upstream of the SCR catalyst, where it reacts with nitrogen oxides to produce nitrogen and water vapor, reducing harmful emissions.
  • The Euro 6d-temp standard applies to the 1.5 Blue dCi 95 and 115 variants from 2019-2020, as well as the 1.7 Blue dCi 150 from 2019-2022, while the stricter Euro 6d standard applies to the 1.5 Blue dCi 95 from 2020-2022 and the 1.5 Blue dCi 115 from 2020 onward. Both emission standards require SCR technology, which accounts for the shared 16-liter tank specification across all configurations.
  • The 1.7 Blue dCi 150 is the only larger-displacement engine among the listed configurations, yet the AdBlue tank capacity remains identical to the 1.5-liter variants at 16 liters, indicating a standardized tank design across the Mégane IV platform regardless of engine output.
  • All capacity values are listed under normal use conditions, meaning the 16-liter figure applies to standard driving cycles rather than severe or extended-duty operation.
  • The 1.5 Blue dCi 115 DPF Euro 6d appears across two separate year-range entries, covering 2020-2023 and from 2023 onward, with both sharing the same 16-liter AdBlue capacity under normal use conditions.
