Nissan Ester Oil is part synthetic or full syenthic

I was pretty sure it wasn't a synthetic. Weird how Nissan recommends an oil change at every 3750 even if it really is a synthetic.

Seeing how easily this oil shears out of grade to a 20 weight within the first 3K miles on various Blackstone UOAs, I'm not surprised that Nissan wouldn't recommend OCIs longer than 3750 mi. Personally, I wouldn't push this oil past 3K miles unless I was doing only low-speed driving where oil temps never got above 220 deg F.

Seeing how high the flashpoint is, about 230 deg C, I would suspect that the base stock oil is probably a PAO with very little, if any, conventional oil in it.

Most of the Blackstone UOAs I've seen on this oil in a VQ37VHR engine look okay at the 3K to 4K mile mark, except for a consistent hot viscosity breakdown from a midline 30 weight to an upper 20 weight. I'm running NEO in my Z but will not push it past the 3K mark if I'm planning on doing any kind of spirited driving.
I do believe Nissan's claim that this particular oil reduces engine friction significantly, as I get 32 to 33 mpg in 6th gear at about 60mph on a level highway. My combined highway/city mileage is about 18mpg - I often late shift and run at higher revs than necessary. My good highway mileage was a surprise to me as I was not expecting highway mileage numbers that good in this car, a Prius it is not.

As for Nissan I don’t see why they are recommending going 3750+ on OCI’s on anything more than normal conditions when the oil analysis I have seen are showing not going past 3K miles is a good idea using NEO regardless of being synthetic or dino based.
