Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1994 Eclipse 1.8L.

Body PASSENGER CAREngine 1.8LTransmission Automatic 4-spd

The 1994 Mitsubishi Eclipse 1.8L is a passenger car powered by a 1.8L engine and Automatic 4-spd transmission, achieving EPA fuel economy ratings of 21/28/23 mpg with a 4.0 qt oil capacity compatible with 20W-40, 10W-30, or 5W-30 API viscosities. Reliability data for this specific year shows 43 total owner complaints and 3 recalls, with the Power Train cited as the top complaint area. When viewed against the model's history from 1990 to 2012, which saw complaint volumes peak at 392 in 1995 and drop to 1 in 2011, the 1994 Eclipse sits at a lower threshold of reported issues just before the lineage's highest recorded year for owner grievances.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the 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 1994 Mitsubishi Eclipse represents a low point in federal-reported issues within its first generation, continuing a downward trend in complaints (43) and recalls (3) from the early 1990s. This contrasts sharply with the 1995 model year, which saw complaints spike to 392—nearly nine times higher—alongside a surge in recalls (13) and technical service bulletins (46), signaling systemic problems likely tied to a mid-cycle refresh or component changes. The 1994 model’s complaint profile is relatively balanced, with power train (8) and electrical system (5) issues leading but no single failure mode dominating; crash (7) and fire (2) complaints remain modest. Positioned at the tail end of the generation’s most stable phase, the 1994 Eclipse avoids the escalating reliability concerns that define the 1995–2001 period, though its low complaint volume may partly reflect survivor bias in older vehicles. The data implies this is one of the stronger years to buy in the first-generation Eclipse, provided a thorough inspection confirms the absence of the power train and electrical issues flagged in the federal record.
