Why didn't you run it to 4K per the recommendation?

While it doesn't fix an injectors that's too far gone, if it doesn't fix your stiction issue, you do get your money back.

Did you regualrly drive your truck on the freeway?

Driving your truck on the freeway is how the additive works best, while this is based on my experience with it and the trucks I've used it on, I'm sure it's not far off from Lubrication Specialties recommendation.

 

Well again as I stated it was just my view from 1800 mile standpoint and I recognize the 4k call. I Personally worry about driving it too much more on that bad injector. I agree on your statement IRT too far gone injectors. I was just making a statement of what I've seen halfway to the 4k recommendation. I'm curious now if I can run another 2k as is to see if she does clear up..... I am starting to see a puff of white smoke at start up.
