CHICAGO -- In a move that will make the concentration of detergent in all grades of its gasoline higher than the Environmental Protection Agency minimum requirement, BP announced it will use a proprietary additive called Invigorate.
BP spokesman Scott Dean told the Chicago Tribune the new formula is from one of the nation’s largest suppliers that also serves Chevron/Texaco, BASF and Lubrizol. The chemical composition is a secret, Dean noted. However, the exclusive BP and Amoco product was designed to better clean intake valves, which provides a better air/fuel mixture to the combustion chambers unimpeded for better engine performance and fuel economy, the paper reported. Emissions are reduced when the fuel mixture is burned properly.
For regular gasoline, it is 2.4 times the EPA minimum. For midgrade it is three times and for premium, four times the minimum, reported the paper.
