Additional Notes
- The Hupmobile Model D (six cylinder) 518-D carries a manual transmission fluid capacity of 1.2 liters, which is consistent with the relatively compact gearbox designs typical of mid-1930s passenger car transmissions.
- The 6-month service interval assigned to the 518-D under normal use conditions reflects a time-based change schedule rather than a mileage-based one, a common approach in an era when odometer-driven maintenance tracking was less standardized.
- The 1.2-liter capacity figure applies to the 1935-1936 production span of the 518-D without variation between those two model years, indicating a consistent transmission specification across both years covered.
