Interesting the USA version I have has a different viscosity oil than yours. (30 vs 40) |
I really don't think anyone would notice any difference. I am sure your manual will advise either can be used. There will be a slight viscosity difference at elevated temperatures but not too much more than that and it is probably comes down to 95% marketing and 5% technical. The Shell 40 is being marketed as being great for twin turbos and even M. That enables it to be sold at a premium price.
