1984 Toyota 4Runner

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1984 4Runner.

Transmission Manual 5-spd

The 1984 Toyota 4Runner utilized a 4-quart oil capacity with recommended viscosities of 15W-40, 20W-40, or 20W-50 API SL, paired with a manual 5-speed transmission and EPA fuel economy ratings of 16/19/17 mpg. Reliability data for this model year records only two owner complaints, with tires representing the top complaint area, and zero recalls. This positions the 1984 variant at the favorable extreme of the 4Runner's reliability spectrum, registering fewer complaints than any year within the 1990-2026 historical range, which peaks at 707 complaints for the 2003 model year and bottoms out at five for the 2026 model year.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 1984 Toyota 4Runner predates the federal record provided, which begins at the 1990 model year and covers subsequent generations — meaning the target year sits entirely outside the documented complaint, recall, and TSB arc. The only federal data points available for the 1984 model year itself are minimal: two total complaints (one in tires, one in suspension) and two crash-related complaints, with zero fire complaints reported. By contrast, the earliest years in the dataset (1990–1994) show a relatively modest complaint baseline of 50–85 per year with 2–4 recalls, after which complaints climb sharply through the mid-1990s and peak dramatically in the early 2000s — but this trajectory reflects later-generation vehicles and cannot be extrapolated backward to the first-generation 1984 truck. The data does not specify root causes for the two 1984 complaints, nor does it provide any recall, investigation, or TSB figures for that model year. **Bottom line: with effectively no federal complaint footprint, the 1984 4Runner cannot be evaluated through this dataset — a prospective buyer should rely on a thorough mechanical inspection and enthusiast-community reliability records rather than federal data when deciding whether to purchase.**
