Fuel treatment for new emission

[freighthaulerjim]

Just want to see what you guys think about diesel fuel additives In a new emission diesel truck

I was told by a rep from cummins to stay away from it

I have three new trucks with6.7l cummins. Was curious what you guys run and why you use additives like
Stanadyne
Lucas
Fppf
Etc???

Just curious if u think it helps or hurts

If you are purchasing clean fuel from a reputable supplier, you do not need anything for the new Dodge 6.7L... That fuel system is designed for the current fuels available...
Most consumer available diesel now has 5% bio or more for a little added lubricant over the original ULSD.
If you need something for cold weather, you should still use an anti-gel....

Are you buying street fuel or do you have your own tank you fill out of?

Whatever they tell you is the fuel filter change intervals, cut it in half and that will solve a lot of issues. I change fuel filters on my F250 with every oil change, never had a problem - but I change my oil every 5-7k. Over kill, yes, but it's also highly tuned.

Do you have a link for that statement?

The best I could easily find is

Several commercial premium diesel products have incorporated the positive benefits of biodiesel as a component of their multi-functional additive packages.

From what I have read some places are selling b5 without advertising but other sell straight diesel. I run safeway diesel and I have read its likely b5. Bio does lubricate better but there is also more of a opportunity for a plugged fuel filter. At b5 I would think the risk is really low.

I change my fuel filter at the book interval because the filter works better as it loads up, until the point it becomes too restrictive of course. I always watch my fuel pressure to see if there is any negative change or lag.

I run a 6.7 Cummins and I run an additive (schaeffer diesel treat 2000). A lot of folks say they are snake oil but I think the small amount of money I paid is worth it. There are so many different opinions on the additive issue.

Seems Foxtrot08 knows what he is writing about.

Thanks for the link. I think I will start shortening my fuel filter change interval. The 15k interval in my book was before all the bio mixing. Changing it sooner certainly won't hurt anything.

Maybe its a regional thing, but every diesel pump in North Texas has a 5% bio blend sticker right on the pump, I can take a picture if you would like one.
The Cummins 6.7L has a dual stage filter that is capable of running beyond 5K miles... provided one doesnt get a bad load of fuel. My 5.9L used to get changed every 5K, but I have extended it to 10k miles, 5K has just been a waste of time and $$$.. but I am careful about where I purchase fuel from.
AS for which brand of snake oil to buy, I'm staying out of that one... that like getting into an Amsoil vs. the world debate...
I will say that I use none of them... if I need to test a faulty FCA, sticking injector, etc.. I use 2 stroke oil... but purely for testing purposes..

What is it with people who think there are some great gains for minimal expense. Just my adding mystical elixer to the fuel tank, oil sump or to thier own diet.

I do not know... there are a few diesel additives that I have seen actually work... but have not seen any that help the newer regen type diesels that have the DPF, SCR, exhaust systems. The new 6.7L Cummins has a rating for max. allowable bio blend, the new Ford 6.7l is B20 compliant. If it won't run right on clean ULSD, its pretty much headed for the shop anyway..

I have often wondered if there is really that many people buying z-max, slick 50, motor honey, etc...??..
