Peugeot 508 II, R8

Manual transmission fluid capacity & service interval

Peugeot 508 II, R8 manual transmission fluid specifications cover capacities ranging from 1.7 to 2.9 liters depending on configuration and fill type. The data includes dry fill and service fill options with and without fins. Two configurations are covered in the data.

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

TypeSpecifications
508 II 1.2 PureTech 130, HNS (2018- )

  • Capacity 1,7-1,8 liter
  • Code: MB6 6/1
508 II 1.5 BlueHDi 130, YHZ (2018- )
  • Use: Normal
  • Capacity 2,2 liter (Dry fill with fins)
  • Capacity 2,9 liter (Dry fill without fins)
  • Capacity 1,9 liter (Service fill with fins)
  • Capacity 2,6 liter (Service fill without fins)
  • Code: ML6C 6/1

Additional Notes

  • The Peugeot 508 II 1.2 PureTech 130 with HNS transmission carries a manual transaxle fluid capacity of 1.7 to 1.8 liters under normal use conditions, reflecting a range rather than a fixed value.
  • The 1.5 BlueHDi 130 with YHZ transmission presents four distinct capacity figures depending on fill type and whether the unit includes cooling fins, making fluid quantity selection more involved than on the 1.2 PureTech 130.
  • A dry fill on the YHZ transaxle with fins requires 2.2 liters, while the same fill type without fins rises to 2.9 liters, a difference of 0.7 liters attributable to the additional internal volume when fins are absent.
  • Service fill capacities on the YHZ transaxle are lower than dry fill figures in both fin configurations. With fins, a service fill calls for 1.9 liters, and without fins, 2.6 liters, since residual fluid remains in the unit during a drain-and-refill procedure.
  • The gap between dry and service fill on the finned YHZ variant is 0.3 liters, whereas on the non-finned variant the gap widens to 0.3 liters as well, indicating a consistent retained volume regardless of fin configuration.
  • Both transmission types are classified as transaxles, meaning the gearbox and final drive share a common fluid sump, which accounts for the relatively higher capacities compared to a standalone gearbox.
  • All rows carry a normal use condition, meaning the listed capacities and any associated service intervals apply to standard operating circumstances rather than severe or first-change-only scenarios.
