Diesel always higher hereWas always cheaper than non-leaded here too, but earlier this year it seemed to go more expensive than non leaded for a short while, then back down again.
Most French cars are diesel so, maybe Macron tried seeing how people would react? He soon did another u-turn, if so!
I think the EU is trying to phase out Diesel. In fact, I think the EU is trying to phase out everything!
