Bentley Eight, Mulsanne

Coolant capacity & service interval

Bentley Eight and Mulsanne models require 18 liters of coolant. Service intervals occur every 50000 km or 36 months. The data covers 2 configurations.

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

TypeSpecifications
Eight (1986-1992)
  • Use: Normal
  • Capacity 18 liter
  • Change 50000 km/ 36 months
Mulsanne S (1986-1992)
  • Use: Normal
  • Capacity 18 liter
  • Change 50000 km/ 36 months

Additional Notes

  • The Bentley Eight and Mulsanne S share an identical coolant capacity of 18 liters, which reflects a full cooling system fill rather than a partial top-up volume.
  • An 18-liter cooling system capacity is notably large, consistent with the substantial displacement V8 engines fitted to luxury vehicles of this era, where thermal management demands are considerable.
  • The specified change interval for both models is 50,000 km or 36 months under normal use conditions, meaning whichever threshold arrives first would govern the service timing.
  • A 36-month maximum interval, regardless of distance traveled, indicates that coolant degradation over time is treated as a factor independent of mileage accumulation.
  • The normal use condition tied to the 50,000 km / 36-month interval applies uniformly across both the Eight and Mulsanne S configurations for the 1986-1992 period.
