I've looked around everywhere and can't find anything saying if I can or can't use any 'ole anti gel formula! I've got a whole bottle of Power Serve. but if I need to get something more taylored to the ULSD then so be it!

The temps are sure falling around here and it's getting to be that time, just don't want to put the wrong stuff in!

 

I haven't heard any problems from people using Power Sevice in there 6.7L. The most popular additive is Stanadyne

 

i talked to my dealer and they said that the fule has to have it. it has to be in there by the gov. also they have a mopar fule something. its about $6.00 a bottle. i tryed it and didnt care for it. Bc its $6.00 per 30 gal's of fule.

 

It should say on the bottles if ok with ULSD. Here's another that is ok to run and also give you the temps it's good to:

Power Service can be used in the 6.7L engine. Some older PS jugs don't have the label on them but it can be used with ULSD as it has been ULSD complaint for almost 2 years now.
