The detergents, aka additives, they put in it are trade secrets for each company. The rumor is among the refiners though is that Chevron Techron is the best performing detergent. They all are pretty much the same though. I must say that they're pretty stingy on how much additive they actually put in which is why you should always just buy the fuel injector cleaner every once in awhile.
