1998 Mitsubishi Eclipse — 2.4L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1998 Eclipse 2.4L.

Body PASSENGER CAREngine 2.4LTransmission Automatic 4-spd

The 1998 Mitsubishi Eclipse 2.4L is a passenger car built on the E平台上 that was powered by a 2.4-liter four-cylinder engine paired with a four-speed automatic transmission, requiring 4.5 quarts of oil with a recommended viscosity of 10W-30 or 5W-30 meeting API standards, and achieved EPA fuel economy ratings of 18 mpg city/28 mpg highway/22 mpg combined; this model year recorded 161 owner complaints with the Power Train system being the most frequently cited issue, and while 13 recalls were issued across the model's span from 1990 to 2012, the 1998 Eclipse falls between the model's peak complaint year of 1995 with 392 complaints and its lowest point in 2011 with just 1 complaint, suggesting a middle-ground position in its reliability trajectory where the complaint volume is notable but not representative of the model's worst performance period.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the 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 1998 Mitsubishi Eclipse sits within a post-spike stabilization arc: after complaints peaked at 392 in 1995, the count fell to 189 in 1996, 170 in 1997, and 161 in 1998, while recalls held steady at 13 and technical service bulletins rose to 72, the highest in that three-year decline. Compared with 1999, which recorded 138 complaints, 12 recalls, and zero investigations, 1998 is slightly higher in every federal metric but still improved over 1995–1997; it also predates the 2000–2001 rebound when complaints jumped back above 314. The leading complaint categories for 1998 are Power Train (21), Air Bags (17), Structure (15), and Engine & Engine Cooling (15), with 23 crash-related and 5 fire-related complaints recorded, though the data does not specify root causes. Given its downward complaint trend and position before the 2000–2001 spike, 1998 is one of the more settled model years of its immediate era, making it a reasonable candidate provided all recalls and applicable TSBs have been addressed.
