Just put some decent fuel in, V Power.

What is learning? just want to check im right on it. cheers.
I did take the battery off so maybe its in learning mode?

Generally do about 2 tanks of v power to 1 tank of esso super,dont know why but if i run it on v power constantly it seems to drop off performance wise, dropping esso super in then going bk to v power seems to keep it sweet.


To be honest though mine runs sound on esso anyway.Only ever put them 2 in it unless forced otherwise.

sounds more like your getting used to the power rather than it dropping power, only solution is mod it,,, lol

I had the fuel issue a couple of weeks ago down in Honiton south Devon,most garages (jet,bp0 didnt actually do super unleaded tesco had it but it was only 97ron so i limped to exeter halfolds and bought two bottles of octane booster to last the rest of the holiday

purge the shell with normal unleaded....you'll get no power loss and the fuel will last longer :-) .....tried it on my mates scooby....works a treat.

[jd]

so you are saying mix V Power with normal unleaded?


that will just give you normal super unleaded at 97ron.

[theevilone666]

Not necessarily 50/50 tho....the thing is the scooby still gets the power and the ecu has been remapped....its like alcohol...just because you might mix 40% proof with 20% proof doesn't mean that you'll end up with 20% proof alcohol .....technically you're just adding some 20% to the 40% ......not that I am saying go out and experiment with that idea...lol...or if you add a mixer to the 40% you're still drinking 40% proof alcohol...no matter how you look at it.....just takes a bit longer(in some cases) lol

Since owning my car (18 months now) I've always put (mainly) Shell 'V' power or Tesco Super unleaded - until Monday night. Went to both petrol stations and neither had any in. The Shell station was having a fuel delivery so thought I may as well go back Tuesday morning. Went back - no 'V' power. Had to fill it up with normal unleaded which I wasn't happy about. Car running ok and seems to be a bit quieter. Been driving it steady though. Will revert back to either of the above if they ever get it back in.

Unfortunately not got a BP station for 20 miles.

dependant on the model of impreza, the ecu will learn and you WILL et more power if using a higher octane fuel mix.

Goes without saying the higher the flammable chemical content in petrol the bigger and more potent the bang....my point was that I was making was that you can purge the 2 octanes obviously not 50/50 and still have the same power as you would with just the high octane....If you go back to wayback when......unleaded first came out...I was putting unleaded in my fuel tank with a gallon of four star as the unleaded didn't have the same lubricating properties as four star,nor did it burn as well. I've spent 19 yrs driving as a legally qualified driver and some of that time has been spent on seeing fuel change and the effects it has on engines and some of that time has been spent pulling engines apart and rebuilding them. And this is my first experience with scoobies so I'm learning rapidly, I will learn even more when I get my own this yr...as I haven't been able to throw it open on the motorway(being as I was picking it up for my mate..who knows little about car purchases on the 2nd hand market)...And I can't wait...Anyway...scooby recommend v-power don't they, what would interest me is....are subaru sponsered by shell...this would explain why they say use v-power rather than a different high octane fuel supplier

subaru always used to just say use 97 ron, not brands or anything like that.

I will stick to Scottimax for mine.

Iv gone back to bp ultimate and its running better again.. on my ppp certificate it says run on 97 so i`ll stick with that instead of learning it.. Gonna get a remap soon enough and then i can go back to V power and hopefully not have the same problem and get more power.

If not i will be modding it! lol
