I use plain normal 95 octane unleaded fuel.. Not ethanol.
But I think the swedish petrol can contain some percentage of ethanol.. About 5%.. Is this bad for the engine?

I can not see this green/red tinge on my plug, more than on the photo..

Edit: looks like Swedish petrol stations are nowadays allowed to put in up to 10% ethanol in the 95 octane unleaded gasoline.. But I don't think it is more than 5% ethanol in it yet.
Perhaps I should get 98 octane unleaded gasoline instead of 95 p, or even 99 octane?
