I have used Primrose in my PSD and now use it in my Duramax. It is the best. You will also notice a difference in engine smoothness.

I use Stanadyne with every fill up in the winter. Not as regular in the summer but it is a very good product. I know alot of guys use it with good results! I bought mine through DIS in texas. Hope this helps!

Cheers, Justin

Stanadyne and Power Service both make excellent diesel fuel additives
