Subaru Impreza 2010: Can the RS fit a Holden LS1 engine?

Answered by CarsGuide 22 Feb 2019

It won’t fit without a lot of engineering. If you seriously want to do it you will need to talk to a qualified engineer recognised by Vicroads, and have a large amount of money at your disposal.

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.

Holden Commodore: What's a good replacement?

Answered by CarsGuide 17 Feb 2017

All of the cars you name meet your criteria of size, economy, performance and handling.

You could also add the Mazda3 and 6 to the list.

Of all of those I would nominate the Camry as the great all-rounder.

Subaru Impreza: What is the right oil?

Answered by CarsGuide 21 Dec 2012

We checked with Subaru and were told that you should follow the manufacturer's recommendation for engine oil as specified in the owner's manual. Subaru also told us that 0W-20 engine oil is available in Australia and can be purchased through Subaru dealers. They also said that you could rest assured that although the engine will not be delivering maximum power, maximum torque, best fuel economy or best exhaust emissions, no harm will have come to the engine by using 10W-40 engine oil.

Subaru Impreza 1997: Timing belt replacement interval?

Answered by CarsGuide 23 Dec 2010

Subaru says the belt should be changed every 100,000 km or four years, whichever comes first. If it hasn't been changed since new then it should be changed as soon as possible.

Subaru Impreza 2006: Why won't it start?

Answered by CarsGuide 11 Sep 2009

WE CONTACTED Subaru with your question and asked for their response, which was: ``We recommend the use of fuel additive SA718 every 6000km to prevent flaking of carbon in the combustion chamber that can be caused by additives in some brands of petrol. Typically what happens is after a short run, usually just moving the car on a Sunday afternoon to wash it, the additive in the fuel soaks on the carbon deposit in the combustion chamber and causes it to flake off. Because of the characteristic of a boxer engine with its cylinders lying on their side, the flaking carbon falls onto the seat of the open exhaust valve. When the engine is cranked to start the carbon particle prevents the closing of the exhaust valve. This means no engine compression and therefore the engine doesn't start. The spark plug is soaked in fuel and this also prevents starting even if the carbon particle becomes dislodged during the cranking. If the engine starts it often runs roughly for a while as the excess fuel is burnt off. The additive that we recommend, SA718, acts to counter the additive in the fuel and stops the carbon from flaking.''

Subaru Impreza 2005: Can a WRX be converted to LPG?

Answered by CarsGuide 18 Sep 2008

THE short answer is yes, but it might not be all that easy. There is no technical reason why it can't be done successfully, but you need to find an approved kit with emission compliance and an installer experienced in doing the conversion. I would talk to WRX specialists and get their opinion.
