Well in Italy we’re not so distant with a +180% ca.
Fuel taxes in Germany are €0.6545 per litre for conventional unleaded petrol, plus Value Added Tax (19%) on the fuel itself and the Fuel Tax.
so the 19% VAT is 30cents + 65 cents petrol tax is 95 cents in total for tax
the remaining 65 cents are for fuel price and profit
so it's more like 150%-200% but not 300%
I can't vouch for the accuracy of either of these sites but they have nice historical price charts:

Italy also doesn't seem to be even close to 180%: https://tradingeconomics.com/italy/gasoline-prices
