Hello, In the instructions for use of the car is only “OZ 96”. 90% of all petrol stations with me have only 95 Super. Gasoline with OZ96 is not available here at all. There is a single one that has 98 Super Plus. I first filled the 98er. Can I refuel the 98er Super Plus without any problems? Could I also take 95er? (is the only thing there is everywhere…) The car is a Lancia Fulvia from 1975. Thanks
