Does 99 RON make much difference?
I filled my blob STI with Tesco 99 RON for the first time on Sunday. It may be my imagination but my car definitely seems to like it. The throttle response seems better and it seems noticeably quicker.
Am I imagining this or does 99 RON really make much of a difference?
Until about a month ago I always filled my car with V-Power but my two nearest Shell stations both closed recently so I've been using Esso 97 RON for the last few weeks.

With 97 Ron the ECu will pull some ignition timing to stop det. On 99 Ron it will allow full timing so the engine will be more responsive. I normally run on Tesco 99 as I fill up when shopping.
