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.
