Hongqi LS7/Guoyao

Differential fluid capacity & service interval

Hongqi LS7/Guoyao differential fluid capacity ranges from 0.9 liter to 3 liter depending on configuration. Four configurations are covered in the data.

Additional Notes

  • The front differential across both the LS7 4.0T and the Guoyao 4.0T carries a capacity of 0.9 liter under normal use conditions.
  • The rear differential capacity of 3 liters is notably larger than the front, which reflects the greater mechanical load and gear volume typically housed in a rear differential assembly.
  • The Hongqi LS7/Guoyao rear differential holds more than three times the fluid volume of the front unit, a ratio consistent with rear-biased torque distribution architectures common in large SUV platforms.
  • The LS7 4.0T covers model years 2022-2024, and both front and rear differential capacities for normal use conditions are identical to those specified for the Guoyao 4.0T.
  • All four rows carry a normal use condition designation, meaning none of the listed capacities are adjusted for severe-duty or first-change scenarios in the available specifications.
