Additional Notes

  • The Ford Model T (USA) differential fluid capacity is specified at 680 grams, a weight-based measurement rather than a volume figure, which reflects early automotive service practices where gear lubricants were often measured by mass due to their thick, semi-solid consistency.
  • A single capacity value of 680 grams applies across the entire 1909-1927 production span of the Model T, indicating no variation in rear differential fill quantity across model years.
  • The specification is designated for normal use conditions, meaning the 680-gram fill quantity is tied specifically to standard operating circumstances rather than severe or first-change scenarios.
