Higher Octane fuel

[Chris Canning]

Unless you retune the engine to take advantage of the higher octane you will not get the benefit from it FACT.

That's complete tosh my 1100s is like night and day between stock fuel and 98/99 octane and I do nothing to it,I don't see such a vast improvement on either my K/Tiger/or XT but there's a difference alright,well in actual fact the with the K it even says on the filler 98 only.

Some interesting reading on the Shell site. They state the benefits with premium is the additives,which clean and protect engine. Anyway,watch the Ferrari/Shell film. Got to be the best commercial ad ever!

Sounds like that may be a benefit, above all else, in markets where there is less ethanol in the higher octane fuels. Over here they started with ethanol being added to the higher octane fuels and then added it across the board.

Doesn't BMW and the 1100s have a knock sensor, so effectively it is retuning itself to run the higher octane.

I view it as a tractor engine that runs better when I feed it good fuel  :icon_wink:
