I'm not doubting it but it would have to work over long periods of time with the detergents, is there a price difference? I work for BP and we used to be able to get our gas at the plant. When the 87 was blended you could just imagine what was added for performance LOL. Nobody ever had to buy the 93 Ultimate which is clear like water, you could see the 87 was the same way. The station has since been removed and now I have to buy Chevron.Still great gas! I know nitrogen enriched gas could have Nitrates similar to Nitromethane and others. I'm sure it's a propreitary blend and until we enrich our gas I'll never know what it really does.
