I have never used Slick 50 in any of my vehicles. I recently bought a container of it at an estate sale. Any remarks on it's use, either pro or con? My 07 LT2 has 138,000 miles with the oil changed every 3,000 - 4,000 miles with Valvoline 5W-30.

 

It will do nothing for you're engine. Plain and simple. In fact, read about this

Yeah, it wouldn't even do anything for coughs, colds, sore holes, nor ring around the doofer. Other than that, it does make a good paperweight.

Other than that, it doesn't seem that it harms anything. :)

 

I think they had a class action against them or them under a different name.

I did put it in my car once, many years ago, Didn't notice anything pro or con.

But, you seem to be into spending your money on un-needed oil changes.

 

Haven't heard slick 50 in a long time.

 

Snake oil. And no need to change your oil any sooner than the DIC says it's time to. The days of the 3k oil change are long past.

 

I like watching this guy. He is unbiased in his test of things.
