2006 Mitsubishi Eclipse — 2.4L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2006 Eclipse 2.4L.

Body PASSENGER CAREngine 2.4LTransmission Automatic (S4)

The 2006 Mitsubishi Eclipse 2.4L is a passenger car powered by a 2.4-liter engine paired with an automatic (S4) transmission, requiring 4.5 quarts of 5W-20/10W-30 API oil and carrying EPA ratings of 20 city/26 highway/22 combined mpg. Within the 1990–2012 Eclipse complaint history, the 2006 model year recorded 99 owner complaints—far below the 1995 peak of 392 yet well above the 2011 low of one—placing it in a middle band of reported issues for the nameplate. Service brakes stand out as the top complaint area, and with four recalls on record, this year reads as a reasonably representative later-model Eclipse rather than a standout problem year or an exceptionally clean one.

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 every 60,000 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 shows a low‑complaint period in the early 1990s, followed by a pronounced spike in complaints and recalls from 1995 through 2001, after which numbers fell sharply to a trough in 20042005. In 2006 the Eclipse recorded 99 complaints and 4 recalls, representing an increase from the 2004‑2005 lows but still far below the peak levels seen in the late‑1990s. Compared with the adjacent years, 2006 complaints are higher than 2004’s 14 and 2005’s 6, yet slightly lower than 2007’s 107 and 2008’s 71, while recall counts remain steady at 4, matching 2005 and 2007. The data do not specify any root cause for the 2006 complaint rise, so the reason remains unknown. Consequently, given its modest complaint and recall figures relative to the generation’s worst years and its similarity to neighboring years, the 2006 Mitsubishi Eclipse can be regarded as a reasonable used‑car option, contingent on a thorough pre‑purchase inspection.
