Now to be frank, given how infrequent this treatment needs to be done, the price differential should be immaterial but I am kind of guy who likes bargains, so I fell for this and ordered a 4-pack from Advance Auto.
The Sierra I got yesterday with 120k miles was very sluggish and erratic idle.
Ran 2 cans of seafoam thru it half a can at a time and let sit 10 minutes before a spirited drive to flush it out.
Each successive treatment smoked less and less and by the time I finished the second can very little smoke show happened.
So all those guys yippin about there being no need for it and whatever else are dead wrong.
My idle now runs at a steady 500,it's like night and day as far as responsiveness is concerned and it was easy to do.
I'm looking to get an inverse oiler for this truck too.
