Thanks Don.
I did the numbers and came up with it costing about half as much as Mobil1 over the 20,000 miles Neo says you can run on an oil change.
Of course, doing the filter change at regular intervals helps to extend the life of an oil change. So you have to figure that every time you change the filter, you add a volume of oil equal to the filter volume, thus adding fresh additives to the existing oil.
The specs look impressive, so it was just a thought.
Thanks again for wealth of information provided.
