Friend owns a CPO 22 E350 with the 264.920 engine and left it with me for an oil change.
MB service information lists the following oil options in this order: 229.71 (0W-20, 5W-20), 229.61 (0W-30, 5W-30), 229.72 (0W-20), 229.51 (0W-30, 0W-40, 5W-30, 5W-40), 229.52 (0W-30, 0W-40, 5W-30, 5W-40).
It is my understanding that most dealers are filling the "older" 264 engines with bulk 229.52 5W-30; the newer 264 engines are now requiring 229.71/229.72 only.
Question A: Based on the Lubrizol comparison tool, I am not seeing any advantage to using 229.52 over 229.71. 229.52 appears to be a low-saps oil that was originally developed for diesel applications. 229.71 appears to be developed for gasoline engines and has more detergency, presumably making it more suitable for long drains. Thoughts?
Question B: What is the difference MB 229.71 and 229.72? For the 2022 revisions, Lubrizol's tool shows 229.72 to have slightly stricter fuel economy standards. In the market today, I noticed that very few oils are approved for 229.72 and of the ones that are, they are also approved for LL-17FE+. MB is also mandating 229.72 only for certain higher performance models (e.g. GLE450 and AMG GLE 53 4MATIC+ Coupe), which leads me to believe that 229.72 has some performance benefits over 229.71?
On the other hand, 229.71 oils tend to be cross-approved for DexosD, VW 508/509 and Porsche C20.
