The 5W-30 will reverse all the negatives above and for top performance, a good performing 0W-30 is the hot ticket.

It is 2007 and not 1968 anymore, but unfortunately, as I mentioned above, sometimes you can't teach an old dog new tricks and their minds are stuck in 1968. Sometimes the grey haired bifocal crowd are not very open minded to new technology, which is unfortunate. A thicker oil, like the product you mentioned, is in fact not as wise a choice as a comparatively thinner oil that will flow faster, transferring heat away from the engine quicker and getting to critical engine parts that need lubricating as quickly as possible on engine starts so as to reduce engine wear and avoid metal-to-metal dry starts. With a good , true PAO based synthetic oil, it is unnecessary to use a comparatively thick viscosity. I have another thread in this forum regarding this very issue about thick oil improving engine protection or not. So if you want the best engine protection, get that thick oil out of your engine and use something better, that flows faster to help reduce engine operating temperatures, extend engine life and reduce engine wear. In your example, for this reason the Mobil 1 is actually the superior performing product to the lower performing Castrol product.
In my own daily driver, in search of superior fuel economy to beat the coming $4 a gallon fuel prices, I am going to be switching over to AMSOIL 0W-20 and again give the proverbial finger to the Big Oil industry! lol

If anyone wants something superior, that is of course their prerogative.

By the way, I think I should clarify that when I recommended Mobil 1 would be the better choice, I was referring to Mobil 1 0W-30 and not 0W-40. The
0W-40 viscosity is the incorrect viscosity for an Infiniti and has several drawbacks, including reduced engine power, reduced performance, increased emissions, reduced fuel economy, increased engine temperatures and an increase in engine wear. 0W-30 is the way to go.

Hope this helps.

Using a thicker oil than needed reduces power output, reduces fuel economy, increases emissions, causes internal operating temperatures to increase as it does not flow as faster and transfer heat as well as a lighter viscosity oil that flows faster. No need or benefit in using such a thick viscosity.
Hope this helps.

How about I just look in my owner's manual? It's what I did when I posted in here.
