no the car had been mapped (most likely on 99 ron) and they had suspect been using lower octane, the car had worn valve seats and low compression as a result.
The fact of the matter is you can most likely run a standard impreza (non sti) on normal 95 unleaded with no problems. They even state in the manual and fuel cap to run minimum 98 i believe on the STI's, even if you used lower then that the standard ECU would most likely still pull timing to accomodate but it wont run as good or meet power and in the long run would most likely do damage.
If you have a car mapped on 99 and you use lower you literally do run the risk of blowing it up, so either carry around octane booster, use the right petrol or if you get stuck use the highest you can find and run off boost until you can get some decent stuff in.

Anybody wants to add to this? I've always used "Wynns" but haven't for abit after using this. Stick to V-power.

That's a different argument to this though. This is about increasing octane to match what the engine was mapped to, not increasing power.

I know I know... I just wanted opinions whilst somebody previously mentioned the "octane" word.

 Where did I say that was the plan? 
My Car has had a map specifically for higher octane fuel. I did what Barnshaw suggested and ran it off boost. I filled up this morning with Optimax and have since used half the tank - so hopefully the cheap shit is nicely out of the system!
I'll pickup some Octane booster at the weekend for the event of this happening again.
On a similar topic, I was at Scooby Clinic today getting a service done - and there was a chap there who was getting a remap because the previous owner of his car had it mapped for Optimax - and the new owner was 60miles away from a Shell garage, and needed it remapping for the Total "optimax" equivelant. How's that for anal?

yea thats normal, its probably just a tweek, presumably you mean Shell Vpower, which is 99 ron, if he can only get to a Total garage then i understand their super unleaded is 98, therefore lower octane hence it needing the map adjusting

Sorry yeah I meant VPower vs the Total stuff... still goes to show how sensitive these maps (apparently) are!
