U.S. base oil producers this week completed a roundof paraffinic price increases that began last week. Six more suppliers followed a pattern set by ExxonMobil Jan. 27, adding 2 cents per gallon to light and medium grades, 4 cents to heavies and 6 cents to bright stocks.
This was the first complete round of price movements since August, although suppliers of Group II-plus oils lowered their postings in November. Citgo imposed its markups Jan. 28. ChevronTexaco made its effective Sunday, while ConocoPhillips, Calumet, Valero and Sunoco all moved Monday. Motivas increases were reported last week.
