London - Oil markets edged higher on Tuesday to hover just below a more than two-year high struck the previous session after a blizzard on the US East Coast boosted demand for heating oil.
US crude for February was 30 cents higher at $91.30 a barrel by 1138 GMT. It had reached a peak of $91.88 on Monday - the highest since October 2008.
ICE Brent crude traded 9 cents higher at $93.94.
A weaker US dollar also provided support, although volumes were extremely thin across financial markets in end-of-year holiday trade.
The bulls pointed to a series of positive economic figures that could stimulate fuel demand.
"Data in recent weeks have been supportive of the stocks and commodity markets globally. The U.S. will avoid a double-dip.

"I think a lot of people are expecting prices to turn higher towards $100 a barrel next year."

For oil-consuming countries, the sustained commodities rally has raised concerns of inflation, but OPEC ministers have said a change in output policy would only be justified if there were a significant shift in fundamentals of supply and demand as opposed to a speculative price rally.
The latest data from the U.S. Commodity Futures Trading Commission on Monday showed money managers had extended their net long crude oil positions to a record high.
The latest indications of fundamentals of supply and demand for the United States, the world's biggest oil burner, will not be released until Wednesday and Thursday. Figures published last week showed a big drop in crude inventories, although they were still higher than a year ago.
