"When US officials say they don't see how the terrorists' oil is smuggled to Turkey... It smells badly of a desire to cover up these acts," the ministry said on its Facebook page.
"The declarations of the Pentagon and the State Department seem like a theatre of the absurd," the statement added, suggesting that Washington "watch the videos taken by its (own) drones which have recently been three times as numerous over the Turkey-Syria border and above the oil zones".
His comments came after Moscow accused Ankara of profiting from the trade.
Russia and Turkey have in recent days traded allegations that they are involved in the illegal trade, further ratcheting up tensions after Turkish jets downed a Russian bomber on the Syrian border.
The State Department has dismissed Moscow's charge against its NATO ally, which directly implicated President Recep Tayyip Erdogan and his family in the trade, insisting there is no evidence to support it.
Instead, US officials told reporters, the oil pumped in eastern Syria is refined in ad hoc desert pits equipped with crude stills and sold on the war zone black-market within Syria and neighbouring Iraq.
Allied officials estimated the IS group's income from oil at $1.0 million to $1.5 million per day, but hope that renewed US, British and French air strikes have cut that.
