Toyota Starlet, P
Differential fluid capacity & service interval
Toyota Starlet, P differential fluid capacity is 1 liter. Service intervals include checks at 10000 km/6 months or 15000 km/12 months and changes at 30000 km/24 months or 40000 km/24 months. The data covers 5 configurations.

Additional Notes
- The Toyota Starlet P series carries a uniform rear differential fluid capacity of 1 liter across all engine variants and model years covered in the specifications, spanning the 1.0, 1.2, and 1.3 engine configurations on the KP6 platform.
- A 1-liter differential capacity is a relatively modest figure, consistent with the compact rear axle housings found on small economy cars of the late 1970s and early 1980s, where minimal fluid volume was sufficient to lubricate a light-duty differential assembly.
- The 1.0 KP6 and 1.2 KP6 variants produced in 1978-1980 and 1979-1980 respectively share identical service intervals: a fluid check every 10,000 km or 6 months and a full fluid change every 40,000 km or 24 months under normal use conditions.
- For the 1981-1984 model years, all three engine variants — the 1.0, 1.2, and 1.3 KP6 — share a revised interval schedule: a check every 15,000 km or 12 months and a change every 30,000 km or 24 months under normal use conditions.
- The shift from a 10,000 km to a 15,000 km check interval between the earlier and later production periods represents a 50 percent extension in the distance-based inspection frequency, while the time-based check interval doubled from 6 months to 12 months.
- Despite the extended check interval in the 1981-1984 specifications, the fluid change interval was reduced from 40,000 km to 30,000 km, meaning later-production vehicles required more frequent fluid replacement by distance even as routine inspections became less frequent.
- The time-based change interval of 24 months remained constant across both the earlier and later production periods for all variants, indicating that the calendar-based replacement schedule was unchanged regardless of the revised distance thresholds.
- All five specification rows are designated for normal use conditions, meaning the listed check and change intervals apply to standard operating environments rather than severe-duty cycles such as towing, off-road use, or extreme temperature exposure.
