Yeah, I found it strange that Anthony states grade 50 as I knew that the factory spec is 40. Anyway, I will be happy as long as I can get rid of the noise regardless of the grade.

Any owners here with noisy engines?

It could be that the previous oil was a 30 oil. Which is actually less "noisy" cos it's less viscous. I personally do find a diff between 30 and 40 oil. Both in terms of sound and "smoothness". But for the price of a Shell 5w40, saved quite a bit of money there. And, the oil does what it's supposed to do. Lubricate and keep the engine clean.
