I was picking up some Power Service silver the other day and I noticed a change in the labeling. On the front of the bottle it now reads "ULSD formula". I really didn't notice anything else that was different and probably wouldn't have noticed that except that the containers, old and new, were sitting side by side. Smart marketing I guess. I was in a Flying J a couple days later and was surprised that the price there had gone up about $5 a bottle on the 3 quart size. It went from $14.99 to $19.99.

 

I noticed that too last time I bought some. Flying J was pretty $$. Walmart was still $14 or $15. I can't remember. I bet the formula hasn't changed.
