SINGAPORE, May 6 (Reuters) - Oil fell more than $1 to a six-week low under $79 a barrel on Thursday, as the euro slumped while global stock markets tumbled on fears that Greece's economic crisis may spread to other European nations.
The euro fell to a 14-month low as scepticism that Greece can deliver on its promises of strict austerity measures dominated the markets. Spooked investors turned to safe havens such as gold and the dollar, pushing their values higher. [
] [ ]U.S. crude for June delivery <CLc1> slid as much as $1.10, or around 1.3 percent, to $78.87 a barrel by 0702 GMT, the lowest intraday price since March 1 when it hit $78.70.
The contract dived more than 3.0 percent on Wednesday to below $80 a barrel for the first time in six weeks after U.S. government data showed crude stocks at the key storage hub in Cushing, Oklahoma, rose 1.6 million barrels to a record of 36.2 million barrels.
London Brent crude <LCOc1> fell 85 cents to $81.76 a barrel.
"There is still room for the euro to further decline against the dollar. Oil could possibly go down further," said Ken Hasegawa, commodities sales manager at brokerage Newedge Japan.
"We have to be careful how the euro will perform in the next few weeks."
Oil becomes more expensive for holders of other currencies when the dollar strengthens.
U.S. crude has seen strong support at $79, but prices may be capped at $82 on Thursday, Hasegawa added. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

]NIGERIA, U.S. DEMAND MAY SUPPORT
News of the death of Nigerian President Umaru Yar 'Adua may create more uncertainty about the country's oil production. [
]Analysts are also watching the U.S. jobless claims data due later on Thursday for further confirmation that the economic recovery is on track to boost oil demand.
Signs of a recovery in the labour market grew as reports on Wednesday showed job growth among private firms and plans for layoffs falling to their lowest in four years. [
]Latest U.S. weekly oil data showed gasoline demand hit a record high for any April, while diesel consumption has started to recover, analysts at Barclays Capital said in a note.
Still, Energy Information Administration data showed gasoline stocks rose 1.2 million barrels to 224.9 million barrels, well above analysts' forecasts.
"It does finally look as if diesel demand is beginning to join the path that the macroeconomic data implied it had to sooner or later," the bank said. (Editing by Ramthan Hussain) (florence.tan@thomsonreuters.com; + 65 6870 3497; Reuters messaging: florence.tan.thomsonreuters.com@reuters.net))
