Additional Notes
- The Fiat Doblò 263 (EU) AdBlue tank capacity is listed at 14 liters across all four 1.6 Multijet configurations covered in the 2018-2022 specifications.
- A 14-liter AdBlue reservoir is a moderately sized tank for a light commercial vehicle, generally intended to allow refills to align with or extend beyond standard oil service intervals rather than requiring frequent standalone top-ups.
- The 14-liter capacity figure applies uniformly to both the standard transmission and the Dualogic automated manual transmission variants of the 1.6 Multijet 66 kW engine, covering the 2018-2021 model years.
- The 1.6 Multijet 70 kW Euro 6 configuration shares the same 14-liter AdBlue capacity as the lower-output variants, with a model year span running from 2018 to 2022.
- All four configurations are noted as using a selective catalytic reduction system, which is the emissions control technology that consumes AdBlue by injecting the fluid upstream of a catalyst to convert nitrogen oxides into nitrogen and water.
- The capacity specifications for all listed configurations are associated with normal use conditions, meaning the 14-liter figure reflects standard operating consumption rates rather than a severe-duty or elevated-demand scenario.
- The 1.6 Multijet 77 kW variant, covering 2018-2021, carries the same 14-liter AdBlue tank specification as the other three configurations despite representing the highest output level among the listed engines.
