Mercedes Benz 229.3 - OPEL/GM Diesel LL B-025
* The OPEL/GM Diesel LL B-025 standard requires two main properties to the lubricant : high HTHS
and very low volatility to drastically decrease oil consumption. Motul 8100 X-cess 5W-40 is especially
recommended for OPEL 2.0 and 2.2 DTI engines (extended drain interval : computer on board).
* The ACEA B4 performance requires an outstanding detergent/dispersent power and a better
viscosity increase resistance due to soot produced by Direct Injection Diesel engines (excep VW unit
injector engines that require MOTUL Specific 505.01 5W-40)
* The MB 229.3 standard is more stringent than 229.1 in terms of ageing resistance (extended drain
interval : computer on board ), detergent/dispersent power (ACEA B4) and requests fuel economy
performance : 1.2% fuel economy improvement versus a 15W-40 reference.
