I think everyone agrees that there is no agreement on the best brand. Everyone has his/her own brand preference (but I don't believe anyone who claims their engine is quieter and or smoother on the $12/L brand versus $8/L stuff). I buy MB 229.XX approved oil and don't lose sleep over the jug's label. IMO, frequent change intervals are more important.

Paying more for an oil to be shipped from Germany along with its Trump tariff doesn't makes my engine any happier than Mobil1 or Castrol Edge. All oil manufacturers test their competitors' products and formulate their products to meet the same approvals and standards. If there are differences, they never show up in the 5K miles during which any of them reside in my crankcase.

The extent of my expertise is:
1. Finding the oil viscosity requirement and the MB 229.xx sheet number in the OM.
2. Finding the compliant oil brands on MB's fluids website.
3. Purchasing oil at a retail location, confirming the viscosity and MB approval printed on the jug.
Cost doesn't matter to me either -- I just don't understand how 2 approved oils can be differentiated on the basis of an arbitrary psychological metric, nor why this should be decisive in purchasing.

Why do some people prefer Coke and others Pepsi? Why do some people drink rot-gut and others pay $4,000 a bottle for whisky? It is preference. Oh, and I do not allow Pepsi in my kitchen.
