European emissionsMobile sources - Pollutant exhaust gases created by the combustion of fuel. Water and CO2 are not included in this category, but CO, NOx, and hydrocarbons are and are thus subject to legislative control. All three are emitted by gasoline engines, while diesel engines also emit particulates that are regulated. Stationary sources - The release of sulfur oxides and particulates from power stations that can be influenced by fuel composition. Local authorities control the sulfur content of heavy fuel oils used in such applications. regulations continue to become increasingly stringent – vehicle manufacturers (OEMs) have had to evolve their hardware designs and integrate these with advanced after-treatment systems to ensure compliance.

BMW introduced their Longlife-04 specification back in 2004, responding to hardware changes implemented to meet Euro 4 emissions, and upgraded further in 2009 when Euro 5 emissions came into effect. BMW recognized that the existing tests included in their Longlife-04 specification needed revised to ensure the compliance of their latest gasoline direct injection (GDI) engine systems with the introduction of Euro 6 hardware in 2014.

BMW developed new engine test requirements such as the BMW N20 durability test for advanced gasoline cleanliness and durability in GDI engines. This has been included in their lubricant approval specifications to supersede the BMW N52 durability test. All BMW Longlife-04 approval applications will require supporting BMW N20 test data from December 2018 onwards.

This latest generation of BMW’s Longlife-04 lubricant performance standard will ensure the availability of formally approved lubricants. This enables oil marketers to continue to address their channel partners’ needs in this growing global market space whilst retaining backwards compatibility to a wide selection of the existing BMW range.
