Fuel additives

[6.7LRigby]

Are these good additives for the Cummins 6.7L?

What does RAM recommend? OH, nothing? I know that Ford recommends a FOMOCO additive, however I have never seen a RAM recommendation.

From the 2015 diesel supplement:

• Commercially available fuel additives are not necessary
for the proper operation of your Cummins®

From the 2018 diesel supplement:

• In addition, commercially available fuel additives are not necessary for the proper operation of your Cummins diesel engine. However, if seasonably adjusted fuel is not available and you are operating below 20°F (-6°C), Mopar Premium Diesel Fuel Treatment (or equivalent) may be beneficial to avoid fuel gelling.

It looks like they recommend both of them, or am I missing something?

Thank you for the reply.

No additives needed for proper operation, ok. But I was thinking about maintaining a better 'health' of the engine. Or...??

Thank you for your reply

Yep, you can go 500K miles with a fuel supplement and 499K miles without one. Filtration is more important than additives. The newer RAM have a good filtration system with the Racor sourced primary filter plus an engine mounted secondary filter. The 2019's may have a different primary filter according to some that have watched the videos and looked at pictures.

When I ran additive, I used Stanadyne. not an endorsement, just saying. I recently was told that Power Service contains alcohol, which apparently is not good. I have read that you want to avoid products with emulsifiers, and you want demulsifiers which help push the water to the separator. This will be even more important with the CGI 6.7 with the CP4. The Cummins endorsement is pretty bizarre.

Well.....as of recently, Cummins has been OK with Power Service in regards to promoting their product.
Required? No.....

Endorsed? Yes....

Who warranties the RAM engine? Not Cummins!

Warranty was never brought up by any of the other posters.....not sure why YOU chose to interject it now. Will Power Service kill the warranty? I’d be more concerned running that AZZZ/OIL stuff in my crankcase than Power Service in my fuel system.

Who do you think steers the recommendations on oil viscosity, service intervals, etc. Definitely not Ram. If it is being endorsed or recommended there is merit, that is for sure. The ad specifically calls out fuel gelling as a concern, for those that live in climates that have wide temperature swings it is a real problem.
This is something that Cummins has recommended for a long time. Just because Ram doesn't necessarily promote it really only tells me they're only concerned about getting you through your warranty.

I believe you’ll find Cummins recommends Power Service for the same reason it endorses Valvoline Premium Blue. It does no harm. It performs as advertised and Cummins has a marketing agreement with the company. That includes display of the product in a prime location at the dealership and favorable pricing for Cummins.

 

[GAmes]

I think the Business Wire article misrepresents the facts. Reading their literature I can find no "recommendation" to use additives. They just put the Fleetguard brand on theirs, so they sell it. Now they sell Power Service. I suppose that having an interest in the product is a tacit recommendation, but as jhenderson pointed out, it is marketing. How many of you don't use Fleetguard filters or Valvoline Blue and don't think a thing about it? https://www.cumminsfiltration.com/sites/default/files/LT36503.pdf is a link from their Power Service page. https://www.cumminsfiltration.com/additives

The brand isnt as important as using SOME type of antigel during unseasonably cold temps. Anyone that lives in a part of the world that has a true winter season and has dealt with unconventional cold spikes in temps undoubtedly has a story or can relate to an instance of fuel gelling if they have been around long enough. The only exception I'm aware of is areas that sell #1 fuel and for 2 reasons. 1, because it is in nature a lighter fuel (significantly less parafin which causes filter plugging) and 2, there is no mixing of biodiesel with #1 which raises the cloud point of fuel and makes it all the more important for the correct dosing when unloaded at the retailer location. Again, you are relying on individuals to play chemist to ensure the proper (antigel) additives are used and assuming the underground tanks are sealed. Im sure there is a point where#1 clouds up, but growing up in Wyoming on a ranch I don't recall near the issues ive witnessed in Northern Ohio with #2 B5 and B10.

I don't use an additive year round but I add it to my bulk tank at home during the winter months. Just this year alone I've had to deal with 2 instances of gelled fuel, one at work and one with the wifes car - as a result of NOT fueling up at home - which I discussed in another thread somewhere here recently.

 

[GAmes]

I can't argue with anti-gel in the winter. I toted 50 gallons of gelled fuel (that I had bought in MS) from northern IN to WA one winter. Now if I buy fuel in the south I dose it if heading for the great white north. I have never needed to add anything to the fuel I buy up north though.

I agree. How can a few ounces of "anything" in 35 gallons of diesel fuel, do all the improvements as advertised?

 

[Dan_69GTX]

Regarding the amazon links, that seems very pricy for around here. (Virginia)

I can go to the local Carquest store and buy the 80oz size for about $19. I can go to the local truck (semi) parts store and get the 80oz cheaper than the 16oz on amazon.

Just an FYI.

I guess they can change the cloud point, and my main concern was always lubricity. Again, that will be a concern with the dreaded CP4. The rest of the claims from faster starting, to better mpg, to stopping hair loss, I think are a bunch of hooey.

I guess it is some of the lubricants that are put into warm weather blends that can gell or get waxy in cooler weather. When i drive north from South Florida 8n the winter, i have used stanadyne extreme winter formula (the exact name eludes me right now). I think a small amount can break apart the molecules in the additives that would gel or turn waxy? I use it as a precaution when i think my tank may have incorrectly treated fuel for the weather i might run into

I was talking about additives in general, however, to zero in on anti-gel there is probably some truth to what you posted. My guess is, by the time you traveled from south Florida to your final destination, your fill ups as you traveled north had more to do with anti gel then the additive did.

Take Arizona, the state of extremes. I would bet money that Phoenix has blended fuel or travelers to Flagstaff would be dead in the water. Even here in Snowflake, it was -5 Sunday morning. There is not enough Power Service Anti-Gel on the mountain to make up for blended fuel for all the diesel trucks that flow up this way from Phoenix.
