Massey Ferguson MF 6S

AdBlue (DEF) capacity & service interval

The Massey Ferguson MF 6S uses AdBlue (DEF) fluid with a capacity of 40.9 liters. The data covers 10 configurations of this model.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

All Massey Ferguson MF 6S variants listed across the 6S.135, 6S.145, 6S.155, 6S.165, and 6S.180 power ratings share an identical AdBlue (DEF) tank capacity of 40.9 liters, regardless of transmission type or model year.
The 40.9-liter figure represents the total tank capacity of the AdBlue reservoir, not a per-service top-up volume. A full tank of this size is typical for agricultural tractors designed for extended field operations where frequent refilling would be impractical.
AdBlue, also known as Diesel Exhaust Fluid (DEF), is a urea-water solution used in selective catalytic reduction (SCR) systems to reduce nitrogen oxide (NOx) emissions in diesel engines. All ten configurations listed are equipped with SCR technology.
The Dyna-6 and Dyna-VT designations refer to different transmission families. Dyna-6 is a semi-powershift transmission, while Dyna-VT is a continuously variable transmission (CVT). Despite this mechanical difference, both share the same 40.9-liter AdBlue capacity across all power variants.
The Dyna-VT variants across all power ratings (6S.135 through 6S.180) are specified for the 2021-2022 period, while the Dyna-6 variants carry a 2022 start year. Both transmission types are rated at the same 40.9-liter AdBlue capacity.
All capacity values are listed under normal use conditions, meaning the 40.9-liter specification applies to standard operating environments rather than severe-duty or special-application scenarios.
