West Texas Intermediate crude fluctuated on Tuesday traded close to the lowest level in more than a four-month period amid concerns that stockpiles in the world's largest consumer, U.S., increased for the seventh straight week. WTI for settlement in December added 8 cents to $94.70 a barrel on the NYMEX as of 2:30 p.m. in Singapore, after it reached the weakest level since June 21 at $94.61 on November 1.
