You can just make out the ghost of the English “Unleaded Fuel Only” text at the bottom of the black trim

So one of the more interesting details on the Lancia Betas I’ve seen is that they all have this warning to use unleaded fuel written in French whether it is this little metal plate on the Scorpion or stickers.

I would assume it’s just because of lingua franca, but was it just a thing with Euro manufacturers to include both English and French?
