Has anybody used...
 

The friction reducer that hot shot makes? I used the stiction eliminator when I had my 6.0 and it worked pretty good so I'm wondering if the friction eliminator is worth using in the 6.2. only thing I dont care for really is that is says it swells seals. My truck is new so I don't really need that part of it lol

I don't add any snake oil to mine. Don't need it.

Thats kind of the way I look at it too but I did use the stiction eleminator woth good results . I was tickled with anything that helped my winter start-ups.

Yeah the 6.2 is pretty much bullet proof from the factory!

and here I though it was Mouse Milk... and works just as well. (NOT)


144k and never had an additive.


my last car, 255,000 miles and same NO MOUSE MILK... body failed by rust .. mechanics was fine.

I am not an engineer, but I do work with a bunch of them and they can be a real pain sometimes. However, I have found that they generally know what they are talking about, so when my owner's manual says do not put any additives in the engine, coolant, or fuel, I trust they know better than me what their engine needs.
Plus, who needs swollen seals in a brand new engine?

Thats pretty much where I was with that but was curious about what others thought.
