Quick question about Fuel Additives in the new 6.7. I've always used lucas fuel additives in all my other dodge trucks ie..5.9L and was wondering if doing so in the new engines could cause any problems with the smog control devices or filters.

Thanks

I would only run a fuel additive that says its compatible with diesel particulate filters.

Thanks for your help. I'm not real sure if Lucas has that product yet

Depending where you are, I've had REALLY good luck with Diesel Services Group fuel additive.

I use Miligan's canola oil additive in both the 98.5 and 07.5 dodges and 3 farm case tractors. I went through 3 inj pumps on the 98.5, then started using Miligans no more problems. Been 4 yrs since last inj pump. Could it just happened that way or it could be the Miligan's I don't know. Being a lic hd mechanic, we used to sell both Miligan's and Lucas. We tested both in -30 c weather. 1L each left outside for 10 hrs. Brought inside and tried to pour into diesel fuel miligan's poured and instantly mixed into the fuel with stirring. Lucas came out in globs and we had to stir like crazy to mix. You could still see the lucas from the diesel. The miligan's you could not tell. I'd use miligan's. Just my 2 cents.

My owner's manual says not to use additives, and thats good enough for me. My 5.9 didn't need any either.

THe new diesel fuel does not have the lubercation factors that the older fuel had. Cummins representatives have told me to make sure I add an addative for lubercation and injector cleaner. I use Diesel Kleen and can tell a difference. Working in the trucking industry and dealing with many Cummins folks weekly, I listen to the factory guys.

what exactly have you noticed?

What kind of truck do you have? 6.7L? I'm sure they (the experts) say that about the 5.9L and others...

WE have the 5.9 in an 2005, 103,000 miles. We had a visit last fall from 3 Cummins representatives from the factory in Whitakers,N.C., ISX factory in New York and the other was from the corporate office. They were checking the engine shipping skids for complaince, secuirty and so forth. The representative from the N.C. plant, which is where rthe ISB,ISL engines are manufactured, remarked about the new emmissions and diesel fuel. He stated the new fuels weren't as good due to the lack of luberication properities. He asked if I ran an addative and I reponded Diesel Kleen. He then said, never stop! All diesel engines weather automotive, commerical or marine should have a addative now to keep the fuel pump and injectors lubericated and clean.. I also heard this from an owner of a motor home when his fuel system failed after 17,000 miles. Cummins advised him the same to prevent pump failures and injector failures. Also, change the fuel filter every 10,000 miles. I can say, using the addative, the throttle response is smoother and we get an average of 23MPG by the pen, 27 by the truck display around town to work. Towing a 23' CC boat to the coast and back, 16MPG. We have added the Super Chip programed for towing preformance and an K&N air cleaner. We don't dog the truck, keep it serviced every 10,000 miles and use the synethic Shell oil with a Mobile 1 oil filter.

It's interesting that the manual for my '07.5 6.7 CTD specifically states that fuel additives aren't recommended. I do agree with what you guys are saying but still wonder why D/C made that statement.

That being said, I do use Diesel Kleen but ONLY on occasion. I may start using it more regularly now upon reading your suggestions.

Still, WHY does D/C recommend against additives in the book? Any ideas?
