Are any of the fuel additives worth using? I just read about the bullydog Rapid Power Fuel Reformulator. Are these just gimmicks or do they really work? Especially on new (06) vehicles?

 

There just gimmics on the 2nd gens, thow it does make mine smoke less, but idk... I heard the 06's do need something... You'll get some healthy replies later....

 

most guys here tend to run the power service or stanadyne. There are some more out there that use others but these are the most popular. I use a power service/ marvel mystery oil mix. good results

 

some good old fashioned 2 cycle oil mixed in will help bring up the sulphur level and keep your pump lubed,also do a search on cetaine its suposed to be very good,

 

I use the Power Service, inexpensive, but I am not sure if it works or not. I have ran it from day one, can't hurt, but then again I have had no problems yet with anything (knock on wood)

 

I use 4Plus Premium with BioArmor from DSG. It is a highly concentrated high quality additive. It cost's less then 4 cents per treated gallon. (I get it at a price lower, then what's listed). http://www.dieselservices.com/html/bioarmor/

No matter what Cummins says I believe that a quality additive is a required with all diesels nowadays, this is especially true with the new low sulfur diesel that is coming out.

 

Mix with biodiesel

 

I use PS/MMO mix every tank. A full year use and still running strong.
