Negative. In oils, the "x" in xw-y, is the weight of the oil when cold. There is some variation in this category, but for the most part, a 5w-30 oil is as thick when cold as a 5w-40. If your talking about viscosity when hot, then yes, the 5w-40 will be a bit thicker than the 5w-30.

On the contrary isn't Rotella one of the oils that specifically does Not meet the new standards calling for less zinc in the oil to meet reduced emissions regulations.
That is of course why people like it since the zinc is what protects your motor, but it's also supposedly rotting out your cat's and killing us all
