I was wondering if the winter fuel is not as good as the summer. My 7.3 has been noticeably noisier idling and during accleration. I keep it pluged in for all starts so it is not exteremly cold, and I always let it warm up before I drive it. If thats just the way the winter fuel is, is there a addative I can put in it to make it run a little smoother?

 

Winter fuel sucks, truck is noisier and burns more diesel as well. Its the winterize stuff they put in it.

 

I run the Power Service Fuel Supplement (white bottle).

Seems to help.

Power Service Products, diesel fuel additives, prevent gelling, clean injectors, disperse water, boost cetane, reduce emissions, improve fuel economy

 

Haven't tried "The White Bottle" yet, but if it does help with the winter diesel I might give it a go. I use Diesel Kleen the rest of the year.

 

Also your exhaust backpressure valve will make them run a little noisier when they're warming up.

 

Normal- Yep, I hear the injectors way more clicking away in the winter... Summer time sometimes it just purrs. I have used Howes, Diesel clean, Fords own Powerstroke additive, and a handful of others. They all seem to work great for me. I have a discount on the Ford stuff though, so thats what I run.

 

What do they put in it during the winter?

 

I think its just anti-gel or something isnt it??? I really dont know, but my injectors sure dont like it.

 

Anti gel with lubrication additive since ULSD has lower lubricity compared to LSD. I use howes meaner power cleaner for more power, and howes diesel treat for anti gel. Both are at the fuel co ops so I just buy them.
