I used Shell 100 weight because the local supply shop carried shell and nu-calgon brands, and the shell was in stock and cheaper. It's the same grade as the sunoco 5gs. At this level of quality, I would imagine the different brands are very much the same composition. They may differ a few ppm in minor additives (which may or may not make any difference).
