Right, no Synerlec sightings in this one I've learned. They cut their sodium in half from what it was a couple of years ago in their same SN version then, and apparently added light amounts of moly and boron for the first time. A change in formula like that might mean they had to run all the API-ILSAC engine tests again, unless they are just buying an off-the-shelf additive package from Oronite, Afton, Lubrizol, who knows who else. Anybody know whats going on?
