2008 Mitsubishi Eclipse — 2.4L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2008 Eclipse 2.4L.

Body PASSENGER CAREngine 2.4LTransmission Automatic (S4)

The 2008 Mitsubishi Eclipse, a passenger‑car equipped with a 2.4‑liter inline‑four engine and an automatic S4 transmission, achieves EPA fuel‑economy ratings of 20 city, 26 highway and 22 combined miles per gallon. Its engine requires 4.5 quarts of oil that meets 10W‑30/5W‑20 API specifications, defining its maintenance parameters. Reliability data show 71 total owner complaints for the 2008 model, with service‑brake problems representing the primary complaint area and a single recall issued, positioning the year near the lower end of the Eclipse’s complaint history that spans from 392 complaints in 1995 to just one in 2011. Consequently, the 2008 Eclipse exemplifies a later‑generation example of the nameplate that balances modest performance figures with a comparatively restrained reliability record.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs at 105,000 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 2008 Eclipse sits near the low end of the complaint and recall arc for Mitsubishi’s 1990‑2012 record, with 71 complaints and only one recall, well below the peaks of 392 in 1995 and 314 in 2000. Compared to the preceding year, 2007’s 107 complaints and 4 recalls, 2008 shows a modest decline in both metrics, while the following recorded year, 2011, reports only one complaint and no recalls, indicating a continuing downward trend. Across the generation, the most frequent issue for 2008 is “Service Brakes” (46 complaints), but this is a smaller share of the total complaints than in earlier years where brakes were not the dominant area. The crash complaint count of nine and zero fire complaints suggest a relatively clean safety record for that year. Given the lower complaint and recall figures and the downward trajectory, 2008 is a solid choice if you prioritize a year with fewer reported problems, though attention to brake maintenance remains advisable.
