Additional Notes
- Both the 1.6 JTDm (88 kW) and the 2.0 JTDm (125 kW) variants of the Alfa Romeo Giulietta 940 (EU) share an identical AdBlue tank capacity of 12.5 liters, meaning the two engine outputs do not produce any difference in reservoir sizing.
- A 12.5-liter AdBlue capacity is a moderately sized tank by passenger car standards, generally associated with extended refill intervals before the driver receives a low-fluid warning.
- Both configurations are noted as operating under normal use conditions, which in fluid service contexts typically refers to standard on-road driving as opposed to severe or fleet-duty cycles.
- The AdBlue system in both variants is identified as a selective catalytic reduction (SCR) system, a technology that injects diesel exhaust fluid into the exhaust stream to convert nitrogen oxides into nitrogen and water vapor in compliance with emissions regulations.
- The 12.5-liter figure represents a tank fill capacity rather than a system-level overhaul volume, as AdBlue reservoirs are topped off during routine service rather than drained and replaced as part of a mechanical overhaul.
