Due to this panic buying disaster I now have no access to V Power in my area. They have normal Shell petrol. The other option is Total excellium stuff.
Any advice please as I'm rapidly heading to my light up
2004 UK STi by the way.

 

try tesco momentum 99ron as well

 

I'm not sure I've got enough to get to my nearest Tesco. Bad planning on my part

 

Get someone to take you and buy some, i wouldnt add 95ron on my tank even driving off boost mate.

 

Is it the standard UK map? If so its mapped for 95ron anyway so wont do any harm 99 is kind of overkill for a UK car. The car will probably feel a bit smoother on the 99 but the 95 certainly won't damage to the car that is unless you have had it remapped for 99ron.

 

Read this thread

 

That thread states at the top that the car is mapped for 99ron so may not apply here untill he says if is standard map or not.

 

Uk are not mapped for 95ron. Check filler cap, says super unleaded only.

If its not mapped specifically to vpower or tesco99 then use esso97, total97 etc.
Avoid bp and sainsbury super as subarus just dont like ir

 

Cheers for the advice everyone
Managed to get to Tesco, light came on half way there though so most economical driving I've done since I've had it.
It is a UK standard map.
Thanks for the advice on avoiding Sainsbury's & BP as I was going to fill up at both the other day but neither had any. Good job by the sounds of it.

 

It should kill it using bp etc as ecu will adjust the timing but you would lose a little power
