Oil prices were little changed on Tuesday as investors took a more mixed view toward the loss of Russian refinery capacity after recent Ukrainian attacks while a slightly weaker U.S. dollar offered some support.
Front-month Brent crude futures due to expire on Thursday were 11 cents down at $86.64 a barrel by 1415 GMT while U.S. West Texas Intermediate (WTI) crude futures was up 6 cents at $82.01.
