ForesterMama -
There was nothing updated in the article other than the date from the original text and the stats page showing decreased oil use over time.
I read it several years ago. Apparently you didn't.
The "expert" without any stated qualifications to comment had a vehicle that was qualified under the terms of the class action settlement that burned "several quarts" in "several thousand miles".
That would also fail the oil consumption test that the member reported above and would qualify for a short block replacement, while the CU author as well as the poster would not qualify for that repair with the reported oil use of 6 quarts in 24K.
Therefore your comment..
Unfortunate that a double standard exists here. The Consumers Union writer got an engine replacement when the oil burning was verified, but the average Joe, the OP, you, or I, get the shaft.
is totally off base and an invalid characterization of Subaru's stated policy. Hope they don't sue you for libel. They might if you repeat that untrue inflammatory statement.
As far as oil use in a Subaru boxer - Unlike steady, relatively low speed RPM's experienced in an aviation application, a vehicle motor goes through constant significant RPM variations (especially in a non-CVT transmission equipped vehicle).
High demand, and high heat (you don't get that much at 30,000 feet now, do you) with high RPM's and an oil that is close to water in viscosity gets used.
I use a heavier weight oil in the high temp summer months or when I go on long high speed trips and have no oil usage, and my car is a "problem" year... But it isn't.
Using the recommended 0-20 in the same situation is not the case. It drinks like a fish.
I'm not the only one on the forum with this experience.
