MOSCOW, March 6 (Reuters) -
* Urals crude differentials in northwest Europe fell to their lowest levels in a year, losing 40 cents a barrel on Tuesday on sluggish demand and abundant supplies of alternative grades, while regional plants reduce runs as seasonal maintenance perks up, market sources said.
* In northwest Europe, Vitol sold to Total a 100,000-tonne cargo ex-Primorsk or Ust-Luga for March 21-25 at minus $2.80 a barrel to dated Brent. This compared with an offer from Vitol on Monday at dated Brent minus $2.35 a barrel.
* Litasco offered a similar cargo for March 19-23 down to minus $2.65 a barrel, but withdrew.
* Trafigura offered 100,000 tonnes of Urals for loading from Baltic ports on March 21-25 at dated Brent minus $2.30 a barrel, and a similar cargo for March 17-21 down to minus $2.40 a barrel.
* Weaker differentials in northwest Europe may put extra pressure on Urals levels in the Mediterranean, as sellers struggle to place March barrels and seek to send vessels to northwest Europe.
* In the Mediterranean, Litasco offered in the Platts window 80,000 tonnes of Urals ex-Novorossiisk for March 21-25 loading at minus $2.40 a barrel, but nobody was interested.
