Engine - Excessive Oil Consumption: Overview

BULLETIN NO.: 94-T-59A

ISSUE DATE: February, 2003

CATEGORY TYPE: Engine-16

CATEGORY: General

CORPORATION NO.: 03-06-01-001R

SUBJECT:
Oil Consumption Concern
(Diagnosis/Service Procedure)

Due to the addition of a new internal engine cleaning procedure, this bulletin has been revised and supersedes bulletin 94-T-59, which should be discarded.

MODELS AFFECTED:

All 1991 - 1997 Saturn S-Series Vehicles

CONDITION:

Some customers may comment that the engine is using 1 quart (0.951 liter) or more of oil every 3000 mi. (4827 km).

CAUSE:

Engine oil consumption greater than 1 quart (0.951 liter) in 3000 mi. (4827 km) may be caused by stuck/sticking oil control and/or compression rings. Engine deposits may build up on and around the oil control ring(s), compression ring(s) and piston ring land(s) causing the ring(s) to stick and become less effective.

CORRECTION:

Perform internal engine cleaning procedure or engine repair procedure depending on amount of oil consumption.

IF engine uses 1 quart (0.951 liter) of oil in:

1500 mi. - 3000 mi. (2414 km - 4827 km), perform Procedure-1: Internal Engine Cleaning

1499 mi. (2414 km) or less, perform Procedure-2: Engine Repair

While Saturn still considers oil consumption of 1 quart (0.951 liter) in 2000 mi. (3218 km) to be an acceptable level, the engine cleaning procedure contained in this bulletin may improve oil consumption performance to an even more acceptable level.
