Hello to everyone, As i've watched almost every possible youtube vid of people changing oil in their older Mercs and every oil related topic on benzworld, i started wondering why the oil choice is so vast and quite different in north America. Today i've spent time browsing on Walmart and it is crazy. Every possible flavour or commercial denomination exists. High mileage, HDEO, every imaginable viscosity from a lot of brands. Here if you go to Leclerc or Carrefour, what i believe is the equivalent of Walmart, you get : Total, Shell and the supermarket's brand in 15W40, 10W40, 5W40 and low saps 5W30 C2 and C3 and that's pretty much all. If you go to a specialized auto store you may also find some Castrol and maybe a jug of 0W20 at an insane price. xW30 and xW20 weight oils didnt even exist here before DPFs and low saps requirements. I wonder why they are standard in the USA while it's been exclusively xW40 here for decades. We don't have things such as HM oils and HDEO oils are mostly unavailable to the public or expensive. The smaller oil choice doesnt seem to be problematic. If you dont need something specific for a newer car you either pick the 10W40 or the 5W40 from Shell or Total. Im pretty sure that 95% of gas or older diesel cars on the road being beaters or not have their pans filled with these oils. What's your take on this ? I am very curious about what the oil market is like in other parts of the world as well.
