Oil gains on gasoline demand, technical buying

By Simon Falush LONDON (Reuters) - Oil prices rose slightly on Thursday to around $46 per barrel, supported by demand for gasoline and on technical buying after a sharp fall the previous day. Brent crude futures were at $45.90 by 0429 ET, up 9 cents following a 3.4 percent fall on Wednesday. Gasoline margins in Europe have tripled since mid-October as low prices boosted consumption.
