Will fuel conditioners (i.e. cetane boost, lubricity, etc...)harm my emissions equipm

I just traded in a '14 Cruze Diesel for a '14 GC Summit Eco-D for the wife.

In the Cruze I ran some diesel fuel conditioner for quite some time and it dramatically quieted down the rattle and seemed to make the engine run well. But I was never sure if it was a good/ bad idea long term. Will this stuff damage my emissions aftertreatment in time?

Any idea?

Thanks.

I emailed Power Service Diesel and asked them if their products will harm my Jeep Ecodiesel and or it's emissions. They replied right away and stated that "none of their product will harm any new diesel engine or it's emission when used as directed" I've been using the white bottle in the winter and silver bottle in the summer. 8oz to every tank of #2 diesel. Zero problems and have noticed a increase in fuel mileage in the summer/fall months with the silver bottle. White bottle no mileage increase.

Re: Will fuel conditioners (i.e. cetane boost, lubricity, etc...)harm my emissions eq

I added just a splash of a commercially available fuel conditioner that claims to: raise cetane, lubricate, absorb water, and clean varnish build up; to my 4000 mile GD 3.0D and it makes a hell of a difference in the sound at idle on a cold morning. The vehicle has way less clatter.

Since the vehicle is for my wife and I haven't driven it since I can't comment on any other differences but it stands to reason that less clatter means more lubricity and less shock load on injector components. Higher cetane results in less combustion delay therefore less knock as well.

I don't really try and keep up with mpg closely in my wife's vehicles since she spends a lot of time just idling for work plus the terrible traffic where we live so I'm not sure I'd be a good candidate to comment on any mpg improvements.

For those very cost conscience I paid $8.12 for a container that claims to treat 250 gallons so if I assume 25 mpg and if I measured carefully not overusing the product (I won't) the cost is non-existent at .0013 cent per mile, or basicaly $13 per 10K miles of usage.

I like the sound and I feel that the sound is indicitive of other good things happening so I'll continue to run the stuff.

The brand I used was made by FPPF and was called "Lubricity & Fuel Power" as they have several diesel products. we keep it on the shelf at the Kenworth truck dealership I sell trucks at so the actual cost for a walk-in is like 20% more as I get a small discount.

PS. It was pain to put the additive in with the capless filler valve so I guess I'll recruit the funnel included with the spare.

PSS. A friend at work tried a splash in his 7.3 and it really quieted that thing down as well.

I've put in quart of 2 stroke oil when filling up, Lucas ash less. I found while it may increase mpg, the extra cost of the oil becomes a break even.
