SUBJECT:
Engine Oil Consumption
INTRODUCTION
As part of our dedication to customer satisfaction, Subaru
of America, Inc. is initiating a program
to extend the original New Car Powertrain Limited Warranty coverage for excessive engine oil
consumption on applicable vehicles to 8 years / 100,000 miles from the original warranty start date.
This Warranty Extension will not cover any excessive engine oil consumption found to be a result of
any condition(s) other than those specifically described in this bulletin.
This condition must be verified during an inspection and when determined necessary, an oil
consumption test performed by an authorized Subaru
retailer. SOA will inform vehicle owners this
condition may exist via a customer letter. For vehicles within the coverage guidelines listed in this
bulletin, customers can schedule an inspection appointment with an authorized Subaru
retailer.
IMPORTANT: ALWAYS perform a Vehicle Coverage Inquiry on Subarunet to determine
eligibility for this Warranty Extension before proceeding. The VIN should also be checked for any
open campaigns or recalls at this time. See sample inquiry result below.
Effective immediately through April 21, 2017, ALL affected vehicles, regardless of mileage and
warranty start date will be covered for these repairs. All inspections and repairs must be completed
prior to the April 21, 2017 expiration date of this Warranty Extension.
IMPORTANT: In the event a vehicle has exceeded 100,000 miles prior to April 21, 2017, please
contact the Subaru
Claims Team at: 1-866-782-2782 to register the mileage PRIOR to claim
submission.
After April 21, 2017, this coverage extends the vehicle’s Powertrain Limited Warranty as it applies
to excessive engine oil consumption to 8 years / 100,000 miles from the original warranty start date
providing additional coverage for some vehicles. All inspections and repairs must be completed prior
to expiration of this 8-year /100,000 Warranty Extension.

Bulletin Number: 02-157-14R; Revised: 04/13/21

This bulletin contains several important revisions regarding warranty coverage and for determining
when an engine oil consumption test should be performed. Review the entire bulletin to ensure
full understanding of these and other changes.
Immediately delete and discard any electronic or paper copies you may have saved locally as they
are no longer valid. If you have any locally saved copies of Service Bulletins 02-143-13R, 02-14413R and 02-145-13R, delete or discard them as they have been invalid since the original release
date of this bulletin and should never be used. Vehicles confirmed as having an excessive oil
consumption condition which are within the supplied VIN ranges, will continue to be repaired by
replacing the engine short block assembly.
VERY IMPORTANT: Read and understand this bulletin COMPLETELY before starting an oil
consumption test or initiating any repairs.
It is critical to confirm the actual condition prior to attempting repairs. Some oil consumption
should be expected as a by-product of engine operation. Failure to recognize this along with
incorrectly diagnosing the condition can result in unnecessary repairs.
Examples of acceptable engine oil consumption:
•
•
A vehicle not equipped with a low engine oil level warning lamp and found to have an
engine oil level at or below the add mark on the dipstick after having traveled 4000 miles or
more since the last engine oil change does not require an oil consumption test be completed.
A vehicle equipped with a low engine oil level warning lamp** which has illuminated
after having traveled 5000 miles or more since the last recorded engine oil change does not
require an oil consumption test be completed.
The information supplied in this bulletin is only applicable to vehicles within the provided specific
production ranges and confirmed as having an oil consumption rate of MORE THAN one-third
(1/3) of a quart (10.6 fluid ounces) in 1200 miles as determined by an engine oil consumption test.
Concerns related to a possible oil consumption condition are generally initiated when the customer
believes the engine oil level on the dipstick has dropped since the last time it was checked or when
the low oil lamp illuminates. It is important to understand all the factors involved when determining
if a repair is required or an oil consumption test should even be started.
REMINDER: Some oil consumption should be expected as a by-product of engine operation.
How much and when it is consumed varies according to manufacturing tolerances, wear, and vehicle
usage patterns. With the extended service intervals commonly used for today’s engines combined
with one or more of the conditions listed below, it may be necessary to add engine oil between the
scheduled maintenance intervals:
•
•
•
•
•
When the engine is new and within the break-in period (during the first
1000 miles)
When the engine oil being used is of lower quality (other than “Energy or
Resource Conserving” API Classification SM or SN or ILSAC, look for
the
starburst design with GF-4 or GF-5)
When the incorrect oil viscosity is used
When engine braking is employed
When the engine is operated at high engine speeds (continually or under
frequent, hard acceleration)
Continued...
Bulletin Number: 02-157-14R; Revised: 04/13/21
Page 2
•
•
•
•
•
When the engine is operated under heavy loads (frequent carrying of heavy cargo, passengers
or trailer towing)
When idling for extended periods
When the vehicle is operated in stop and go and/or heavy traffic situations
When the vehicle is used under severe temperature conditions (cold or hot)
When the vehicle accelerates and decelerates frequently.
Under these or similar operating conditions, the oil level should be checked more frequently. The
engine oil and filter may also need to be changed more often.
As related information, the low oil level warning light (if equipped) is designed to illuminate when
the engine oil level is approximately 1.1 quarts below full (engine OFF). Keep in mind, oil remains
suspended in the engine while running and will not fully drain back until the engine has been shut
off for at least 5 minutes. For this reason, the oil level should not be checked for at least 5 minutes
after shutting the engine off. See Section 3 of the Owner’s Manual for more information on the oil
level warning system.
**NOTE: A procedure to reduce false illumination of low oil level warning lamp (if equipped)
is provided later in this bulletin for how to address customer concerns of the low engine oil level
warning lamp illuminating prematurely when the oil level is either full or nearly full.
PRODUCTION CHANGE INFORMATION
Redesigned piston rings were incorporated into production as per the table below. Vehicles with
VINs / engine numbers PRIOR to those listed below should be repaired following the procedures
