Hi All,

This has probably been posted before countless times so apologies.

I live in the UK and i read a lot of talk about correct grade of fuel to use in my S.

I have two options of fuel over here its either 95 ron unleaded or 98 ron premium unleaded.I read a lot about US people buying 91 and less and running their cars on this quite happily..Does this mean that i can happily use 95 ron unleaded in my car without problems or should i be using the 98 ron unleaded?

The reason i ask is that petrol costs the same as gold over here and 98 ron unleaded is more expensive so as to save a few pound everynow and then and be able to afford a beer once a week.

Many thanks..

 

Pump octane ratings are not the same in the UK as in the US.
