Hagerty has a video on their website with two Shell engineers. They said that the new formulation of the Shell Nitro+ gasoline premium was especially formulated with older carburetor engines in mind. They said that the fuel has a special formula that would coat the older plastic and rubber parts and protect them from the dangers of ethanol in modern fuels. Also no lead additive was needed for the older cars. Has anyone had any experience with this fuel in muscle cars, carburetor cars etc.?
No experience but here's a link to the MSDS for V-Power Shell gas. Now you just gotta figure out which ingredient does what. I do know that one of the differences between V-Power and Nitro+ is the amount of PEA. Shell advertises this on it's website. Keep in mind, being a Top Tier brand, that all grades must meet the minimum amount of detergents set forth by Top Tier.MSDS
