Ergon, Calumet and San Joaquin Refining will be increasing naphthenic base oil prices this week, joining Cross Oil, which had announced an increase last week. A vast majority of paraffinic base oil producers also communicated increases between 15 and 40 cents per gallon, with effective dates dotted between April 26 and May 5.
Paraffinic base oil suppliers informed their customers that posted prices would be increased by 15 cents/gal, 30 cents/gal and 40 cents/gal, depending on the viscosity and location. Motiva appeared to be an exception, as the producer has not made any adjustments this week. API Group I light-viscosity grades will be moving up by 15 cents/gal, while heavy-vis grades and bright stock will, in most cases, climb by 30 to 40 cents/gal, with these cuts reported to be the tightest and most difficult to source.
