Additional Notes

  • Both the 3.0 TD and 3.5 V6 engines share identical front differential fluid capacities of 1.5 liters, indicating the same front axle assembly is used across both drivetrains in the Vauxhall Monterey B M98.
  • The rear differential holds 1.8 liters across both engine variants, which is 0.3 liters more than the front unit, reflecting the typically larger housing and gear set found in rear differentials on four-wheel-drive platforms.
  • A fluid check interval of 15,000 km or 12 months applies to all four differential positions under normal use conditions, meaning the level and condition of the fluid are assessed well before a full drain and refill is due.
  • The change interval for all differential positions is set at 45,000 km or 36 months under normal use conditions, which is exactly three times the check interval, creating a structured three-check cycle before each fluid replacement.
  • All four rows carry a normal use condition designation, meaning the stated 45,000 km or 36-month change intervals are not adjusted for demanding operating environments such as towing, off-road driving, or extreme temperatures.
