There is some good stuff in here. I cannot believe the dates that are on the first page of this thread. It's been a long speculative road fellas. Some of the info on the first few pages is not accurate anymore.
Instead of debating the cost v benefits anyone looking to this thread should really consider purchasing an Infiniti Elite maintenance package. It covers ester with no question and will pay for itself within the first 30k.
There is a ton of apprehension when it comes to servicing ones car. Everyone has a bad story, hell I have had a few bad days and left a drain plug or two loose.
S happens, where any facility should graded is on their response. I have driven out to customers houses on my own time to address. That is why I tell everyone to not bring their car in on a Saturday, while you are almost guaranteed to not get the technicians full attention. But that is another thread.
I know I have personally said "this stuff works" on more than one occasion. My basis for this is not an oil analysis. I have a trashed vvel engine out on the floor and even after sitting for over a month and the cams still had a perfect coating of oil, unlike the several other engines I have disassembled where the top rotating parts get dry. A carbon analysis and remaining chemical composition test will never tell you details like that. I have noticed idle quality difference when switching, whether the ECM learns to adapt to that one I return the car to it's owner they are not this is one of those things that you use your senses to prove.
Any mechanical engineer should be able to agree that lowering the µ and thermal energy displaced in a normal internal combustion engine will improve efficiency, and economy as well as parasitic loss. We all know that an ic engine runs <30% efficiency on average, while gasoline is full of potential energy. One of the the many ways Nissan is doing this is providing owners with an ideal oil.
It would not really make sense for Nissan to make their own fluid if they could just get some from Motul or Amsoil. There is a bunch of money in that type of agreement. It is not something they appear to be marketing like Porsche and MB do with M1. I am skeptical of the comment that was made in regards to this oil not being used during the design and emissions testing of this vvel engine, everything I have heard goes the opposite way. The vvel technology is a new set of rotating parts added to the cams, that in itself might require special lubrication. Nissan has also been using special finishes on cams and cranks for years, in an attempt to be on the leading edge of efficient technology.
I love a good educated debate, but it's funny that one thing that polarizes people worse than politics is oil.
I saw this picture a while back and thought that it would fit this thread perfect. lol, have a good weekend y'all
