2 engine vs. 4 engine fuel burn

Hello all,

professional SLF here, I just read an article in the April 1st issue of The Economist about Boeing and Airbus and a sentence in there caught my eye:

Meanwhile, the European firm is losing out in the next size up, where Boeing sold 155 of its 777 long-haul planes last year, compared with only 15 Airbus A340's, which suffers from having four engines in a time of high oil prices.
Is that true? Sorry of it sounds like a stupid question but my gut tells me that the fuel use is sensibly the same between two. I do understand that maintenance and all that is cheaper with 2 engines, but fuel burn must be about the same no? The Economist is usually pretty good when it talks about aviation.

This may be apples and oranges, but I am just curious.

Thanks for your help.
