Subaru Liberty (Legacy) 2.0R

[han_chung]

Hi,

In Australia, they've recently released the 2006 Subaru Liberty
(Legacy) 2.0R. It's a DOHC engine and the specs recommend premium
unleaded gas of octane 95 or higher.

Does anyone know the implications of running it on lower octane gas,
other than performance?

Regards,

Han.

As the Late (and great) Possum Bourne once said to me " it'll ping the tops
right off your pistons"

If it has a knock sensor, as most modern engines do, it should just be a
performance/fuel economy issue. (Does somebody know for sure whether it has
one?) I would use premium at least during the break-in period though.

With some engines people have found the effect of relying on knock sensing
to retard the timing makes it about as economical to use premium as regular.

Running on lower octane will cause it to retard the timing, and reduce power
output, and increase fuel consumption - it's cheaper to run on the good
stuff - don't be so tight!

Off-topic but I should point out that in my family we refer to our cars
as Rus, The Red-Ru and the Maroon-Ru have replaced the Blue-Ru which
suffered a bend right front everything.

The implications are that you wont get the performance you bought with
the car for. It will ping, it will stutter it may become a death trap
because of its poor performance. It will use more petrol than if you use
premium.

I suspect that you're trying to save money by using 91 octane.

I can't believe you spent $30,000 on a car and need to save 10c litre to
run it it.

Sell the car!
