Rated 4 out of 5 by from I like the slick 50 brand I originally got this in the past because I was satisfied with the results of using their Engine Treatment. I don't know if the fuel system treatment is better than others (I haven't compared), but it seems to work okay. It was hard to find locally and I had to order online at pepboys.com.

Rated 4 out of 5 by from did the job slick 50 seemed to do okay, wanted royal purple but store didn't carry it, seemed to work about the same as sea foam.

Rated 5 out of 5 by from A Very Good Buy! I have a high mileage vehicle and had been looking for Slick 50 in all of my normal haunt's, however it seems that it were no longer readily available. I spoke with an employee at Pep Boys and he also helped me search the shelf's. No such luck. So he suggested that we order the product. I were expectant at a week wait and they had it available for me two day's later. Glad I followed through and didn't switch to an alternative.
