mobile 0w-40 is still the real deal. don't trust the rest.

 

From what I understand, that particular one is still Group IV. It's a big viscosity range too. Not sure I'd want to run that large of gap

 

Hi flash. Per Infiniti engineers, the recommended viscosity for these vehicles is 5W-30. Using an oil with a thicker viscosity than recommended can cause reduced performance, reduced fuel economy, increased emissions, increased engine wear and increased engine operating temperatures. The Mobil 1 0W-40 is a European oil formulation for European vehicles that recommend a 0W-40 viscosity.
