Hi, Does anyone know if the MB oil specs for LD and HD engines (the 229.x and 228.x series) are more stringent than the ACEA tests, particularly A3/B3? I dont know that Ive seen an oil that has been 229.x rated and not A3. Since the comparrison of 228.x to A3/B3 is not direct due to 228.x being a HD diesel oil spec, how does the 228.x specs compare to the 229.x specs, particularly for diesels? Does 229.x specs take into account chemiustries to deal with Diesel EGR engines, since the engines have been using EGR since the early 80s? Thanks, JMH
