I agree, there is no call for that sort of response.
You probably should do some research at the links mentioned, read them
carefully, and see what you can pick up.
For a long time the Slick 50 product was panned by a lot of people who 'had
heard', or 'believed', or 'imagined' it to be either trash or treasure.
The original lawsuit, I believe, had nothing to do with damaged engines nor
was it about the ability of the product to perform or not. It was that
Slick 50 made
wildly optimistic advertising claims that, when they were asked to document
them, they could not prove. They had not done the homework they claimed
they had. Maybe the product worked, and maybe it didn't, but they had
broached some serious truth in advertising rules.
I have heard a lot of anecdotal commentary about Slick 50 plugging filters,
plugging engines, fouling engines, etc but I have never yet seen proof
positive of this...just opinions, old wive's tales.
It is very possible that some engines have failed into which Slick 50 was
as a last ditch measure, and that the ultimate failure was blamed, rightly
on Slick 50.
It might be bad stuff. I really don't know. I have used it, as I said
before, with never a hint of a problem.
Don't let people dog you. Your question was a fair one, and it is a shame
you have been treated so shabbily. Unfortunately, I doubt that anyone here
the total truth about this product....
