Now I've seen that you have put OMV, in my town I don't have OMV, just Petrom, and Castrol.
I can't buy neither gas with vouchers. 😂
I'm stuck with my Bitcoin in my wallets 😞

Have you tried crypto creditcards? Nexo is not too bad. Regulated outside EU. Virtual credit cards works. Of course again not the optimal way but still a way. Try with small amounts. Custodial risk exists, bit still cool.
(Not endorsing Nexo, or getting payed in any way.)
