LONDON, June 21 (Reuters) - Oil extended gains to rise more than $1 on Tuesday, with traders looking to buy in at lower levels, taking advantage of weakness in recent sessions, while a lower dollar also supported prices.
By 0713 GMT U.S. crude for July delivery was traded $1.06 higher at $94.32 after it closed at $93.26 the previous session.
The dollar index <.DXY> was down 0.4 percent. A lower dollar makes crude more attractive to holders of other currencies.
U.S. crude is still down 8.2 percent this month after it fell almost 10 percent in May, pressured by worries about the demand outlook.
