(Adds close of U.S. markets)
By Herbert Lash
NEW YORK, April 28 (Reuters) - Oil struck a record near $120 a barrel and U.S. stocks were little changed on Monday as caution ahead of a key Federal Reserve decision on interest rates this week overshadowed optimism over a $23 billion takeover offer for chewing gum icon Wm Wrigley Jr Co <WWY.N> .
The Dow closed lower in a late sell-off that also dragged down the broad S&P 500, while the Nasdaq managed to eke out a small gain.
A recent rally in the dollar stalled as investors bought euros to square up positions ahead of the Fed's interest rate decision.
Oil prices hit a fresh peak as supply outages in Nigeria and Britain cut output, but prices retreated from their peaks as the dollar slipped against the euro, reflecting rising but still minor speculation that the Fed may not cut interest rates.
Trading was sluggish before the two-day meeting of the Federal Reserve Open Market Committee gets under way on Tuesday. The FOMC's decision to be released on Wednesday is expected to include a quarter-point rate cut and could mark the end of a campaign that has reduced the Fed's benchmark lending rate by 3 percentage points to 2.25 percent since September.
Another Fed rate cut would further erode an already weak dollar and likely fuel higher prices, especially of dollar-denominated commodities. But if the Fed holds the line on further rate cuts that could cause oil prices to drop.
"We're doing quite well, considering how much we've bounced back from the March lows," said Joseph Battipaglia, market strategist at Stifel Nicolaus in Yardley, Pennsylvania.
"You had a push with that major buyout in the food category but now you're now starting to get comments about the Fed bringing an end to the rate cuts and we're doing well despite that."
Uncertainty over the Fed tempered Wall Street's mood.
The Dow Jones industrial average <
> was down 20.11 points, or 0.16 percent, at 12,871.75. The Standard & Poor's 500 Index <.SPX> was down 1.47 points, or 0.11 percent, at 1,396.37. The Nasdaq Composite Index < > was up 1.47 points, or 0.06 percent, at 2,424.40.Tech bellwethers Microsoft Inc <MFST.O>, Cisco Systems <CSCO.O> and International Business Machines <IBM.N> led tech shares lower.
Microsoft shares closed down 2.8 percent at $28.99 after Yahoo Inc. <YHOO.O> let the deadline for it to respond to the software maker's threat to take its acquisition offer for the Internet company directly to shareholders pass with no new development.
But the proposed takeover of Wrigley by M&M's candy maker Mars Inc and billionaire investor Warren Buffett, and an investor's bid to boost a stake in Ford Motor Co <F.N> showed investors are still willing to put money in areas that hold promise.
Wrigley's shares surged 23.2 percent to $76.91.
Ford shares shot up 9.5 percent to $8.21 after Kirk Kerkorian's Tracinda Corp said it intends to make a cash tender offer for up to 20 million shares of the automaker's common stock at a price of $8.50 per share.
A bleak assessment of the economic outlook, however, by Buffett injected a note of caution. Buffett told CNBC television that the United States could be mired in a longer and deeper recession than most people think.
Weighing heavily on the financial sector was a report from Morgan Stanley cutting its profit forecasts on several U.S. banks, including Bank of America Corp <BAC.N>, whose stock declined 0.3 percent to $38.18 .
European shares advanced, led by banks such as Swiss bank UBS <UBSN.VX> on hopes that asset write-downs are over and miners such as Xstrata <XTA.L> thanks to higher metals prices.
The FTSEurofirst 300 <
> index of top European shares ended 0.6 percent higher at 1,338.60 points -- the highest close since Feb. 27 and fourth consecutive gain.With UBS up 3.2 percent and rival Swiss bank Credit Suisse <CSGN.VX> 2.7 percent higher, the DJ Stoxx bank index <.SX7P> was the day's top sectoral performer with a gain of 1.1 percent, followed by insurance <.SXIP>, up 1.06 percent.
Among mining stocks, Xstrata rose 2.4 percent and Antofagasta <ANTO.L> gained 2.6 percent, lifted by higher copper prices <MCU3>.

Energy prices were higher, but off the day's peak. Prices are up almost 25 percent since the start of the year.
U.S. crude <CLc1> settled up 23 cents to $118.75 a barrel. London Brent crude <LCOc1> settled up 40 cents to settle at $116.74.
"Continued attacks in Nigeria and refinery closures in Scotland ... may see the U.S. target $121-122 a barrel this week, with longer-term charts all pointing to $130 or higher," said Ben Coleman, senior commodities trader at TradIndex.
In currencies, the dollar was down against a basket of major trading-partner currencies, with the U.S. Dollar Index <.DXY> down 0.19 percent at 72.589 from a previous session close of 72.728.
The euro <EUR=> was up 0.10 percent at $1.5639 from a previous session close of $1.5623. Against the Japanese yen, the dollar <JPY=> was down 0.25 percent at 104.14 from a previous session close of 104.40.

Investors have pared bets that the Fed will aggressively cut benchmark interest rates. Fed funds futures indicate an 82 percent implied chance of a quarter percentage-point cut in the recommended overnight lending rate between banks when the Fed concludes its meeting.
In Asia, Japan's broader TOPIX index <
> gained 1.6 percent or 21.84 points to 1,361.75. MSCI's index of stocks across the rest of Asia <.MIAPJ0000PUS> rose 0.5 percent.
