An oily question

[d_barker@xxxxxxxx]

I put in Slick50 the first oilchange I did on the 67 2 years ago and almost 
immediately developed a knock. I changed oil again and went back to the 
QuakerState 10-40 that my father-in-law used for 30 years and noise went away. 
One of my workmates later told me that Slick50 has lawsuits against it for 
ruined engines. Apparently it contains parrafin and had a propensity for 
clogging things in some cases.
