ExxonMobil Synergy Diesel Efficient

Has anyone run ExxonMobil next generation diesel fuel? They claim it improves fuel economy, reduces emissions and runs cleaner, and keeps injectors clean.

I've run a couple of tanks of this fuel not paying attention to the fuel economy, but I did notice a decrease in regen frequency which means it should improve fuel economy. Because of the improvement in miles between regens I decided to look at ExxonMobils website to see if there is something special with their diesel fuel and low and behold there appears to be a new gen diesel fuel being phased in.
