JAC M1 / Refine

Additional Notes

• The JAC M1 / Refine rear differential fluid capacity is specified as a range of 1.6 to 1.9 liters across all listed engine variants. A range rather than a fixed value reflects normal manufacturing tolerances in housing volume and the fill-to-overflow method typically used during service, where fluid is added until it reaches the level plug opening.
• The same 1.6–1.9 liter capacity range applies equally to the standard rear differential and the limited slip differential variant across every engine configuration listed. Limited slip differentials use a friction-modifier additive in the fluid, but the physical housing capacity remains unchanged from the open differential specification.
• The 2.0-liter petrol engine configuration carries the earliest coverage in the specifications, with entries beginning in 2002-2015 as well as a separate entry starting from 2008. Both share the identical 1.6–1.9 liter rear differential capacity under normal use conditions.
• The 2.4-liter petrol engine appears in two separate entry groups, one starting from 2008 and another from 2011, both specifying the same 1.6–1.9 liter rear differential capacity for normal use. The presence of two distinct start years suggests different production series or regional variants of the 2.4-liter configuration.
• Two diesel variants, the 2.5D and 2.8D, are listed with entries starting from 2008. Despite the difference in engine displacement and fuel type, both diesel configurations share the same 1.6–1.9 liter rear differential capacity as the petrol variants, indicating a common rear axle assembly across the M1 / Refine lineup.
• All specifications across every listed configuration are designated for normal use conditions. No severe-use interval or capacity variation is listed for any of the rear differential entries, meaning the 1.6–1.9 liter fill range represents the single service fill reference for standard operating conditions.
