1986 Toyota 4Runner

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1986 4Runner.

Transmission Automatic 4-spd

Defined by its automatic 4-speed transmission and an engine requiring 4 quarts of specific multi-grade oil (15W-40, 20W-40, or 20W-50 API SL), the 1986 Toyota 4Runner returned EPA fuel economy figures of 15 city, 17 highway, and 16 combined mpg. The model generated just 12 total owner complaints focused on Engine & Engine Cooling, alongside zero recalls. When contextualized within the 1990–2026 complaint history—which saw a high of 707 complaints in 2003 and a low of 5 in 2026—the 1986 4Runner's low complaint volume places it firmly on the reliable end of the spectrum, meaning researchers will find fewer systemic faults here than in the nameplate's most problematic years.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 5,000 mi; spark plugs every 30,000 mi; coolant every 30,000 mi. The big-interval services (every 30,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

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 federal record for the 1986 4Runner is sparse, with only 6 engine complaints, 2 crash complaints, and no fire incidents reported—far lower than any year in the 1990–2026 dataset, where complaints often number in the hundreds. Because the provided year-by-year data begins in 1990, there is no direct comparison to earlier model years, but the 1986’s complaint count is dramatically below the rising trend seen from 1990 onward, which peaks in the 2000s before declining. The absence of recall data for 1986 in this record means potential safety issues are not captured, but the low complaint volume suggests the first-generation 4Runner in its third model year is relatively reliable. Given the minimal reported issues, the 1986 4Runner appears to be a good buy, though buyers should independently check for any unlisted recalls.
