Ukraine was not able to interrupt production of gasoline and diesel in Russia in a significant way after two years of targeting oil refineries. Then attacks on pipelines and their pumping stations were not effective either as Russia was able to repair damage within days and weeks. And then all Russian oil terminals on Baltic and Black seas are operational again albeit in reduced capacity after big Ukrainian attacks few weeks ago. Apparently 50-100 kg warheads that Ukrainian drones deliver is not that effective at damaging oil infrastructure.

This may change if Ukraine can sustain what they were doing last couple of months, but so far Russia benefits extremely well from US war against Iran.

Why do i get downvoted? It was reported that russia even stoped gasoline exports due to this.

They're preparing for an invasion of Taiwan, and if they do that the US will cut off their oil supply, so they need the reserves. They're betting they can take Taiwan fast enough that they can present a fait a complis, and negotiate a re-opening of trade routes before their reserves run out.
