2017 Ram

I use Power Service Anti Gel with no problems.

Nope, no issue that I've seen or heard and fwiw, the fuel system is basically the same from 03 to present on these trucks.
By the same token, regular use of an anti gel like PS 911 is not reccomended nor needed. It's to liquefy a system already gummed up.
Other products are generally not needed at all either unless, say there is an abnormally, almost record cold snap for a particular area, where the fuel may not be treated down to that temperature, or if you're traveling to a significantly colder climate on fuel bought in a warm climate.
Needing a winter additive anymore is purely wives tale for most normal use. Commercially purchased fuel is and has been blended for the weather in the area for years.

Antigel wont hurt the system. Just use a reputable brand.

My area Cummins dealer says it won't cause issues however they did say we were far enough south (my location is in northeast OK) that gelling isn't a issue with todays diesel fuels. Your farther north can make a difference. What does your area Cummins dealers say ??

My company used Power Serve and still gave us a case to use in our depot. Didn't have good luck w/ it, yet PS also makes 9-1-1 (Good Stuff). Not sure who makes Meltdown. Many here will say to use this or that. Howes Diesel treat makes some awesome anti-gel. So does Hot Shot Secret. One of the best options is to make sure you buy diesel from a place that turns it over often and that more than likely, blends it as it gets dumped in their tanks. I buy my fuel at such a place here in NY, but still add anti-gel just as a precaution. Course Ford wants me to use their branded products, but have had very good luck w/ other products.

Cummins now recommends Power Service diesel fuel additives so I would use their anti gel product
