Hi,

Bought my MY04 UK STi (standard) today, and have a few questions on the fuelling.

Are these engines designed for uk standard fuel? Ie 95 octane? I know the imports have to have 97 and above or they die eventually. Will I ruin my engine if I put 95 in for everyday use and the odd blip on the throttle. Obviously for a day when I will drive her hard only the best 98/99 fuel will do!

Can someone give me the facts on this?

Thanks

They will take 95 but run like a bag of shte , so ive heard

ive only run mine on Shell optimax or tesco momentum

do have some octane booster just incase i need to put bogostandard in mind

afaik for them to be UK cars they need to be able to use 95 octane though?

id expect at least 3 replys before i post this from people with alot more knowledge mind

Think my previous MY05 STi Type UK said 98 octane on the filler cap!

I wouldn't run it with anything less than SUL, prefer V Power.

So the engine is only designed for SUL and 95 wont do my engine any good?

majority of the time v-power mate, however when needed in a emergency i use tesco, sainsburys bp super unleaded, but best to stick to v-power!

Minimum fuel for these cars is 97 Ron, do not use 95 Ron!

Do you not have an owners handbook? All sti's need super unleaded, ideally 99 octane which is either Tesco momentum or Shell v-power

Dan-NMF

V power or tesco for me, have used sainburys's 97 with octane booster but still ran like **** and made it miss

My 03 Sti says 98 minimum on filler cap.

Dan-NMF

Right then, 98 is what she wants so 98 she will get!

Don't put 95 in it, and if you really have to then I'd say keep off boost!

I ran my 2 classics on Shell SUL
I've ran my last 3 STI's on Sainsburys SUL
We don't have the luxury of Vpower etc over in N.Ireland

Dan-NMF

Filled her up with v power and it's lovely! These things are actually quite good on fuel! I had to put 95 in it to get it home (no other pumps) it drank that! 98 v power is being sipped even in warp drive!

Why didnt someone tell me scoobies were so good years ago!?

Good on fuel? What did you have before?!?!?!

I wasn't aware there was a 98 ron fuel ;-)

Shell/Tesco - 99
BP/Esso - 97

Before I had a single turbo converted supra at 500 bhp which did about 9mpg lol
