1986 Subaru DL

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

Transmission Manual 5-spd

The 1986 Subaru DL is a compact model that pairs a manual five‑speed gearbox with an engine requiring 4.2 qt of oil, typically serviced with 10W‑30, 10W‑40 or 10W‑50 viscosity oils meeting API SM standards, and delivers EPA‑rated fuel economy of roughly 22 mpg city, 29 mpg highway and 25 mpg combined. Its modest oil capacity and the flexibility of viscosity choices stand out among its contemporaries, while the manual transmission underscores the vehicle’s driver‑focused character. Reliability data show an exceptionally low incidence of owner complaints—only one reported—with the electrical system identified as the primary trouble spot and three recalls recorded for the year. This combination of sparse complaints and limited recall activity places the 1986 DL toward the more dependable end of its generation’s reliability spectrum.

Reliability & federal safety record

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

Owner complaints about the 1986 Subaru DL dominate in one area — the electrical system, 1 of 1 reports (100%), well ahead of the next concern. None of this vehicle's 3 recall campaigns target the electrical system, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 0 of the reports describe a crash and 1 a fire — a small share of the total, but worth weighing against the electrical system pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
