I have used Shell 5w40 Rotella synthetic in several vehicles with great success and would probably use it in my 2012 PF if the warranty did not specify 5w30 grade oil. I have just 8,000 miles on the truck now but after the warranty expires I will probably make the switch.slavabon wrote:Short 1-second rattle on cold start can be fixed by switching o better quality oil filter. The cause for this is your oil draining back from the system. Also, I don't consider OEM oil filters - best quality filters. Some of them Will cause this. Put a Bosch or K&n or equivalent and the rattle should go away. Had this tested several times on 06 Xterra and 2 pathfinders I have owned in the past several years.
The piston slap or prolonged engine rattle that goes away after a few minutes or until the engine warms up is somewhat common in VQ40, at least according to the forums. I think it really depends on how anal you are about noises. Most people don't notice it, but this slight cold engine tapping noise on my 2010 used to drive me nuts, but I can also hear faint piston slap in some new Toyotas idling in the parking lots . Then I started using 5w-40 Shell Rotella synthetic oil (its a bit thicker) and things got better.
