Factory vs. Aftermarket: which oil is better?

Answered by CarsGuide 20 Oct 2017

I would use the factory recommended oil, at least while the car is under warranty. Once the warranty has expired you could use the Mobil oil and shouldn’t experience any problems.

Is it worth replacing the engine on a '09 Subaru Liberty?

Answered by CarsGuide 13 Oct 2017

In going order it’s worth $7000-$9000 depending on condition, so you have to consider if it’s worth spending $5000 on it to get it back on the road. It’s eight years old, has done 180,000 km, it’s probably best to sell it to a wrecker if you can get $2000 for it.

Is Subaru obliged to fix this oil issue?

Answered by CarsGuide 26 Aug 2016

The fact is we don't have the same clout as Americans do, that's because our consumer laws are weak. Your best course of action in the short term is to talk to your dealer about the problem, and have them do an oil consumption test to establish the actual oil usage. If the test proves your assertion that it's using too much oil you will then have good grounds on which to ask Subaru to do something about it.

Subaru Liberty flat throttle?

Answered by CarsGuide 26 Sep 2014

I would be running some fuel system cleaner through it, and cleaning the throttle body.

Subaru Liberty GT fuel additive

Answered by CarsGuide 23 Aug 2013

You don't say what the fuel additives were. They could have been so-called fuel system cleaners or perhaps, given that your car is turbocharged GT they could have been octane boosters. If you detect any pinging you could try an octane booster, but otherwise I would go along with your mechanic.

Subaru Liberty water pump

Answered by CarsGuide 16 Nov 2012

It's common practice to replace the water pump at the belt change, and not just on Subarus, as the water pump is usually found to be leaking when they take off the front cover and belt etc. By replacing it when the engine is pulled down for the belt change you won't have to do it again when the water pump finally fails. If you're not sure ask to see evidence the water pump needs replacing before the mechanic goes ahead and fits a new one. $400 is about right if it has to be replaced.

Ask Smithy Xtra Subaru Liberty E10 enquiry

Answered by CarsGuide 18 Jan 2011

Yes, you can rely on E10 to have the correct level of ethanol. Subaru’s advice is that the 2004-2006 Liberty GT should not use E10, it needs a higher octane rating, but yours could, providing you use fuel of the recommended octane rating.

Change for the better

Answered by CarsGuide 30 Apr 2009

Subaru says the factory-recommended interval is 100,000km or 48 months, whichever comes first. So after nine years the belt should have been replaced twice. Wear depends not only on distance travelled but also time, because rubber deteriorates and wear is accentuated by short-distance driving below normal operating temperatures. There is some tolerance for extending the interval at low kilometres, but Subaru makes no specified allowance for this. You are strongly advised, in the interests of engine durability, to change the belt now. By not doing so you're gambling against a failure, and that's not wise.

Pinging in liberties

Answered by CarsGuide 20 Apr 2006

ACCORDING to Subaru there are no problems with pinging if you use good-quality 98 RON fuel in unmodified engines. A few primary turbos have been replaced because of seizure of the exhaust control valve that redirects exhaust gases/energy to the secondary turbo. Make sure you use good-quality fuel that is fresh. Mobil and BP are two that appear to have a decent shelf life.
