Fuel and Coolant Question
Posted 30 July 2003 - 09:33 PM
What type of fuel is required? I heard the manual states 89 octane? Do many people just use 87, as long as it doesn't ping too much?
Secondly, as far as I can tell I have the traditional green coolant. Where these models equipped with dex-cool, or the other "hybrid" type coolant? I guess I should just use what I have now.
Any other tips? Thanks for the help in advance.

All the normal aspirated 2.5 liters will use 87 octane.
The only subies that require premium are the H6's and the turbos.

I would tend to think that all Subaru engines (at least the newer ones), especially turbocharged ones, come equipped with a knock sensor. In a higher output engine (turbo) with a knock sensor, you could use lower octane fuel without the danger of pre-ignition, but you would experience a loss in power due to the ECU retarding the timing.
So unless the engine is tuned for high performance, it should run well on 87 octane.
