Pro tip: Don't buy those cheap fuel injector cleaning kits off Amazon

I wasted $45 on one of those in-line cleaning kits last month and it did nothing but clog my filter on a '06 Cummins, has anyone else had better luck with a specific brand or method?

Man I learned that lesson the hard way too lol. Tried one of those cheap kits on my old Duramax and it just made everything worse. Ended up taking it to a shop and they told me to just run a good quality diesel cleaner through the tank every oil change. Been using the Hot Shots EDT+ for about two years now, just dump it in before a fill up on the highway. Cleans everything out slowly without wrecking your seals or clogging things up. Way cheaper than those inline kits and actually works.
