Run it for a single duration and test it. Simple enough. The motor and associated emissions controls very likely won't experience any detrimental effects.

How does a consumer test an oil to determine it meets or does not meet the requirements of a Mercedes-Benz approval?Run it for a single duration and test it. Simple enough. The motor and associated emissions controls very likely experience any detrimental effects.
You don't, an oil is either approved or not. (I know this was a trick question) It's like looking at an SDS for oils to see which one is "better"How does a consumer test an oil to determine it meets or does not meet the requirements of a Mercedes-Benz approval?
They really need to develop an approval process for oils. I am tired of having to send my oil in for analysis to see if it meets the required specWhat? Millions of $$ of product development and rigid documented tests can't be validated by a 7oz of oil thrown into the mail and a $30 test?

You were the one who said run it and test it. I just wanted to know how you test it and what you look for.Jesus. This is like fretting about who makes the best burger, but never trying any. Pick one and try it. Use whatever "tools" are at your disposal. Weigh the pros and cons. But is it impossible to just move on? It's motor oil, not a mission to the outer planets.

You're overthinking it. Castrol and Pennzoil 229.51 are the least expensive on the Bevo list when purchased from Walmart; $22 to $25 for a 5 qt jug. If you actually go check the specs, the difference in viscosity and HTHS between the 229.51 30 weights and 40 weights is less than a sneeze. The 40 only gives you some decimal points. Doesn't make me sleep less to use 30 weight.In our case, with the Sprinter, we need an oil that (ideally) is on the Mercedes 229.51 Bevo list, or at least one where the mfr swears on their mother's grave that it meets/exceeds 229.51. Diesel particulate filters (DPFs) are expensive. On top of that, MB over-engineers everything. Any number of things -- like a partially clogged DPF -- can put the Sprinter into "limp home mode" (LHM). That is no fun for the owner, or anyone stuck behind them on the highway. That has not happened to us, and I'm trying my best to avoid it!
