hi every1 ... ... just recently treated myself to a MY05 STI uk car .. and was wondering do i have to run it on high octane petrol or just normal unleaded .. and what effects would it have ( apart from costing me a fortune ) on the engine .... Paul

 

Welcome to Scoobynet

General rule of thumb, don`t use 95ron. Use a higher octane fuel, such as Tesco 99 or V Power.

Regards

Ant

 

Cheers for that Ant Paul

 

Don't use BP would be my advice. Costs a lot & not all that good. Tesco 99 for me

TX.

 

No worries, happy to help.

TX, I`d never buy that fuel. I know a man

 

And for me

 

isent tesco fuel just esso stuff hmmmm !

 

no......its supplied by esso, but that's not the same thing...

 

v power for me, and if its sold out(regularly happens), tesco 99!

 

Your car will run 'OK' on 95RON (assuming its not been modified) but to get the best out of it you definately need to run Super at least, I'm a cheapskate and use Sainsbury's (far and away the cheapest SUL) and get about 5% better economy (so worth the extra) than I do out of '95RON' (note premium unleaded at '95RON' to the relevant BS is allowed to be down to 94RON!).

David at API told me NEVER to use BP fuel. Apparantly it's really bad for the engine

Tesco 99 Bio or Shell 98 V power

 

just driven across europe, dont own a scooby any more as i got into motorbikes but i do miss my v5 STi type R, got a megane sport tourer tdi now...not quite the same lol...anyhow they sell 101 rated fuel here in europe. just did a slog to czech republic to see relatives and also bad news for diesel owners...they starting to put an additive in the diesel that supposed to destroy your engine over time!!!
