NEW YORK, Feb 15 (Reuters) - Oil prices fell on Tuesday, giving back early gains as the dollar briefly turned higher and equities slipped on mixed economic data.
Brent crude felt more pressure as traders eyed the gap between the two benchmarks.
The dollar index <.DXY> bounced off lows after its earlier weakness helped boost oil prices. The euro held on to some gains against the dollar.
Concerns about ongoing Middle East protests and lower-than-feared Chinese inflation also had supported oil prices earlier on Tuesday.
Brent crude <LCOc1> fell 93 cents to $102.15 a barrel at 12:24 p.m. EST (1724 GMT).
U.S. crude <CLc1> fell 47 cents to $84.34 a barrel.
"I see the dollar's move up from earlier lows pulling down NYMEX crude futures," said Chris Dillman, analyst at Tradition Energy in Stamford, Connecticut.
Brent's premium to U.S. crude <CL-LCO1=R> seesawed between $13.24 and $14.90 on Tuesday. Brent's premium to U.S. crude surged to a record above $16 a barrel on Friday, still measuring the two March contracts before the March Brent's expiration.
"That Brent/WTI spread may be getting a little heavy and the focus seems to be on that and less on the data and news today," said Richard Ilczyszyn, senior market strategist at Lind-Waldock in Chicago.
Middle East unrest and the potential for supply disruption remained a concern as police and protesters clashed in Bahrain. Iranian lawmakers urged death penalties for opposition leaders and hundreds of demonstrators and government loyalists fought in the Yemeni capital. [

CHINESE INFLATION
China's consumer price inflation came in lower than expected for January at 4.9 percent. A Reuters poll had forecast 5.3 percent. [
]But core inflation in the world's second largest oil consumer, stripped of volatile food prices, jumped to 2.6 percent year on year, the highest since at least 2002 and up from 2.1 percent a month earlier.

MIXED U.S. ECONOMIC DATA
U.S. stocks slid as a smaller-than-expected rise in retail sales raised doubts about a rebound in consumer spending, a vital part of an economic recovery. [
]Early on Tuesday, some brokers and analysts pointed to supportive data like the New York Federal Reserve's gauge of manufacturing in New York State which climbed in February to its best mark since June. [
]U.S. retail sales growth slowed in January, but at least some oil traders and analysts saw the data as supportive or neutral considering the extreme weather that curbed shopping traffic.
