Synthetic or Mineral lube properties are nearly identical at 3K miles. I like the additive package in the 15w40, keeps things squeaky clean and no ticky lifters. The 5w40 is a must in the winter in MN or IL. I've had issues with 0W40 Mobile One--ticky lifters and erratic oil pressure at idle after warmup.

ReRouting CCV lines on E300 [NON-Turbo]
As far as oil..... Others may chime in. Best to stick with one oil year-round. Different additive packages from different oils may have adverse affects on long term reliability / oil comsumption. Mobil 1 5w-40 TurboDiesel is an excellent oil to run in these OM606's... I have run mine w/ 5k filter changes and topping off to 14k w/o adverse affects confirmed via oil analysis.
No need to get creative with different oils for different times of year. I have run my E300 in cold and hot climates. Since I've relocated to a warmer climate the past 2 years I changed from the Mobil 1 Turbodiesel to AmsOil 15w-40 Heavy Duty Diesel & Marine. Slightly thicker oil, slight margin of additional cushion.
