Kyiv last month adopted sanctions blocking the transit of pipeline crude sold by Moscow’s largest private oil firm, Lukoil, to Central Europe, sparking fears of supply shortages in Budapest and Bratislava. 

[...]

Budapest relies on Moscow for 70 percent of its oil imports — and on Lukoil for half of that amount. Slovakia, which imported 88 percent of its crude from Russia last year, according to the Kpler market intelligence firm, has warned the Ukrainian measure could reduce the crude supplies for its primary refinery by 40 percent.

So if another EU country or the EU commision convinces Ukraine to allow the oil transfers to Hungary again, and it flows on 2025-01-01, this question will resolve as YES.
