Yup that's what I had always thought too. Recently I've become curious if in reality the same exact additives are put into all grades of Shell (or Exxon etc), but just at different percentages - premium containing the highest % obviously. Which means omitting the "corrosion, wear, and friction" language from the benefits of regular-grade is a marketing tactic to push people toward purchasing the more expensive and profitable product. I figure maybe GoldDot40 might know since he works around the terminal and might be able to see if there is a dedicated storage tank of additives just for premium.

But when they talk about the V-Powerd Nirto+ they add corrosion, wear and friction.

So I would say it's a different additive package. www.shell.us/ motorist/ shell-fuels/ shell-v-power-nitro-plus-premium-gasoline.html
