BP Lubricants USA last week informed U.S. customers that prices for Castrol finished lubricants will generally increase by up to 4 percent effective May 6.
Although the March 29 letter to customers gave no specific reasons for the increase, it did note that due to market constraints with some base oils, Castrol reserves the right to limit purchases of select products on a sku basis.
BP indicated in the letter that price changes for certain products may fall outside the general percentage amount.
On March 11, Shell Lubricants notified U.S. customers that prices for Shell brand finished lubricants would generally increase by up to 4 percent effective April 15.
