Oldsmobile Cutlass Supreme (USA / CAN)

Additional Notes

• The Oldsmobile Cutlass Supreme 2.8 V6 (1988-1989) carries a notably wide automatic transaxle capacity range of 3.25 to 5.75 liters. A spread of this kind typically reflects the difference between a partial drain-and-fill service and a more thorough fluid exchange, where the actual amount recovered depends on how much fluid remains in the torque converter and valve body after draining.
• The 3.1 V6 (1989-1993) lists a fixed automatic transaxle service fill capacity of 5.75 liters. A designated service fill figure represents the quantity added during a routine fluid change rather than a full overhaul refill, meaning the torque converter is not fully evacuated during the procedure.
• The upper bound of the 2.8 V6 capacity range matches the fixed 5.75-liter service fill listed for the 3.1 V6, suggesting both engines share the same transaxle family, with the lower figure on the 2.8 V6 entry accounting for partial drain scenarios.
• Both configurations are noted as transaxle applications, meaning the transmission and final drive are housed in a single unit, which is consistent with the front-wheel-drive platform the Cutlass Supreme used from 1988 onward.
• Both the 2.8 V6 and 3.1 V6 entries carry a normal use condition, meaning the listed capacities and service intervals apply to standard operating circumstances rather than elevated-stress or severe-duty driving cycles.
