2001 Nissan Maxima SE automatic
Hi Scotty, Scotty my question is how do I use Slick 50 engine treatment for my Maxima with 205k miles. Should I do an oil change in my car and then pour Slick 50 on top or just put a certain amount of engine oil and then top it off with Slick 50 treatment. How do I go about doing this?
Slick50 is pure snake oil. It will not help your engine. Its only effect is to drain your wallet.
A scam that has been going on for decades...
"The Federal Trade Commission has charged Quaker State - Slick 50, Inc., the manufacturer of Slick 50, the best-selling auto engine treatment in the U.S., with making false and unsubstantiated advertising claims. According to the FTC, ads for Slick 50 that tout tests showing improved engine performance are false and its claims of reduced engine wear are unsubstantiated." (7/16/1996)
