LONDON, April 24 (Reuters) - Oil fell towards $117 a barrel on Thursday amid a strengthening U.S. dollar as traders continued to lock-in profits after its rally to record highs earlier this week.
In contrast, London's gas oil set an all-time peak because of concerns a refinery problem in Finland and a strike that threatens to shut a refinery in Scotland may further tighen fuel supplies in Europe.
U.S. crude <CLc1> fell 72 to $117.58 a barrel by 0951 GMT, dropping for the second straight session after it hit a record high of $119.90 on Tuesday.
London Brent crude <LCOc1>, which also hit a record high of $116.75 on Tuesday, dipped 32 cents to $116.14.
Brokers said Thursday's gains in the U.S. dollar against the euro had added to oil's bearishness, a day after an increase in U.S. crude oil inventories triggered selling by investors.
The euro slid further from this week's record high against the dollar on Thursday after Germany's Ifo corporate sentiment index eased, joining with recent soft data to fray the edges of confidence in the euro area. [
]Crude oil stocks surged by 2.4 million barrels in the world's top energy user last week, double the forecast level, mainly due to an increase in inventories on the U.S. West Coast. [
]Meanwhile, London's gas oil futures <LGOc1>, European benchmark for distillate products such heating fuel and diesel, struck their all-time peak of $1080.75 a tonne.
"The ICE London gas oil contract is a key leading indicator. It is still showing strength, much later than normal," said Jan Stuart, economist with UBS.
Refinery workers at Britain's Grangemouth refinery will begin a two-day strike on Sunday that will shut the plant and squeeze fuel supplies in Scotland and northern England.
Talks between the union and the plant's operator, Ineos, broke down Wednesday over a company proposal to modify the salary pension plan, a union official said. [
]Finnish refiner Neste Oil said its diesel production line would be closed until the end of May. [
]Disruptions of some exports from Nigeria, Africa's largest exporter, were likely to provide limited support to crude oil prices.
Royal Dutch Shell <RDSa.L> on Thursday reaffirmed its outages stood unchanged at 169,000 barrels per day since the latest spate of attacks to its Nigerian oil facilities. (Additional reporting by Felicia Loo in Singapore; editing by Santosh Menon)
