I was told by a GM shop that Stanadyne was the only fuel treatmant approved by GM? Also, I tried a bottle of the red Stanadyne for U.L.S. diesel, and I swear I picked up 1.5 MPG's. Anybody else have this same experience? Thanks!
Probably a stupid question, but here goes. I have a case of Stanadyne Winter1000. I want to run the Stanadyne Performance year round, but want to use up the Winter1000 first. Question is, can I run the Winter1000 additive in the summer too to use it up or should it only be used in the winter...
I am new here so if this question has already been asked.. sorry!!
we are looking at getting a 2001 LB7
My brother recommends Stanadyne. (he drives a 1997 Dodge Cummins) Just want to know who uses this and if you like it or not?? I have heard it it's best.
Oh if you do use it where do...
