Thoughts on FI cleaners RESOLVED THANKS :-p

[GeorgeT]

do most people in the states use premium 98 fuel in their spiders? ...

I believe that octane ratings are different in the US from Australia; the highest generally available grade here is 93 octane (higher grades are available in limited locations). Fiat recommended "regular" i.e. 89 octane.

Examples of octane ratingsThe RON/MON values of n-heptane and iso-octane are exactly 0 and 100, respectively, by the definition of octane rating. The following table lists octane ratings for various other fuels.[4][5]
