It takes a solid 15+ seconds after cold startup before the tell-tale change in cylinder head noises that indicates full lubrication up there (which reminds me to make a point about allowing an overnight-cold car to properly lube itself before driving to extend engine life).
Good oil is worth the investment in my opinion, and something with esters in it is staying in mine, at least until I feel like I've researched this enough to have a firm grasp on the issue.

I too have done a lot of research on oils that will work well with the VVEL system, but I haven't come across any definitive answers as to what types of "esters" are actually in the Nissan Ester Oil. I originally wanted to use Mobil 1 due to it's quick cold weather pumping, lower friction, and better durability in high temps, but I'm going to stick with the Ester Oil until I figure out if another oil is actually safe to use in the LONG TERM with the VVEL system. All the Nissan dealers I've spoke with, as well as Corporate Nissan, have told me repeatedly that the Ester Oil is required and not using it could void your warranty (despite what the owners manual says!!!).
