Additional Notes

  • The Triumph Dolomite 1850 and Dolomite Sprint share identical automatic transmission fluid capacities, with a base fill of 4.7 liters rising to 5 liters when an oil cooler is fitted.
  • The Dolomite 1500 carries a single listed capacity of 5 liters, which applies only to the oil cooler configuration, as no base capacity without a cooler appears in the specifications for that variant.
  • The 0.3-liter difference between the base and oil cooler capacities on the 1850 and Sprint reflects the additional fluid volume held within the cooler circuit and its connecting lines.
  • All three variants share a 10,000 km check interval under normal use conditions, applied uniformly across the 1500, 1850, and Sprint configurations.
  • The Dolomite Sprint, introduced in 1973, carries the same automatic transmission fluid specifications as the 1850, despite being a higher-performance variant with a twin-cam engine.
  • The Dolomite 1850 has the longest production span among the three listed variants, covering 1971-1980, and maintains consistent fluid capacity figures across that entire range without variation by model year.
