Hi i am new to the forum and have recently got a 2006 2.5ltr impreza turbo wrx sti type uk

It came with 3/4 tank in it
I had asked salesman what petrol i should use and he said any type is ok.
However after my 1st fill up yesterday at morrisons, i got home and wasnt sure again if this is ok.
Coul someone please advise me on this,
Thanks Gary

 

I believe it states both in the handbook and on the filler cap for super unleaded only (97+ ron fuel), running on 95 really isnt a good idea, just read the 2.5ltr engine failure thread for that

What would you advise i do now, i have drove about 5 miles on this fuel

 

I would never put anything other than v power or 99 tesco in

 

just don't boost drive carefully and fill up with the good stuff

 

do i need to get the ecu reset, or will it be fine using 1 tank of this and then always use v power

 

you shouldnt need to reset your ecu just put v power in it

 

thanks for the advice, feel a bit better now

 

I always keep a bottle of millers fuel additive in the boot, I believe it adds a couple of "ron", if in doubt of the quality of the petrol, I always add some to the tank.I get it from h..fords,

 

as above either add some octane booster or just run it off boost. I kept mine under 2.5k revs while clearing the tank of leftover methanol and ran it on v-power alone for a couple of tanks worth to get a pure v-power map done

 

ECU will probs adjust things to allow for it, but you could just buy some octane booster and put that in, probs only cost about £5-10

 

thanks
what octane booster would you recommend
