Hi Stu.

The 2.0T says 95 ron only as a guide really. I think it is to stop people trying to put 4 star in!

Mind you petrol with lead in it is rare now, but even the lead replacement petrol can be hazardous to your cat I have heard.

Anyway, the point is, that to obtain full power levels on a 2.0T you do not need anything more than 95 ron. 98 offers no real benefit to it in standard form. There is ALWAYS an improvement but in the LPT car it will be too little to be readily noticed. You may notice it is smoother but probably nothing more.
however if you start to tune it then high octane becomes even more important in the LPT cars as they have higher compression ratios.

Use 98 on your 2.0T by all means but it will not benefit you as much as if it is tuned, or if the weather gets hot, or you drive hard all the time and underbonnet temps are consistently high. Under normal circumstances the 2.0T will produce its 160+BHP with 95ron no trouble at all.

Cheers,
Dan.
