Wait, wait !! ......
We're mixing apples and oranges here as it relates to fuel quality.
USA and Europe use two different octane rating methods...the methods used by USA result in octane ratings typically 5 points lower than similar fuels in Europe.
Meaning? Euro 98 octane = US 93 octane..
Let's be careful out there....some guys are actually "using" this info
