Additional Notes

  • The Maserati Biturbo power steering system holds 0.6 liter of fluid across all listed variants, a relatively modest reservoir capacity consistent with the compact rack-and-pinion or recirculating-ball systems common in performance vehicles of that era.
  • The 0.6 liter figure represents the total system capacity, which typically reflects the combined volume of the reservoir, pump, and steering gear lines rather than a partial service top-up amount.
  • All four variants — the Biturbo, Biturbo 228, Biturbo 425, and Biturbo 430 — share an identical 0.6 liter capacity, indicating a uniform power steering system architecture across the model range from 1984-1991.
  • The Biturbo and Biturbo 425 share the same 1984-1988 production window and the same 0.6 liter capacity, suggesting the two variants, despite differing in body style and engine displacement, used the same steering hardware.
  • The Biturbo 228 and Biturbo 430 represent the 1988-1991 generation of the lineup, and both retain the 0.6 liter capacity, confirming no change to the power steering system volume during the transition to the later model variants.
  • All capacity figures are listed under normal use conditions, meaning the 0.6 liter specification applies to standard operating environments without adjustment for severe or high-stress driving scenarios.
