its time to change the oil again and ive got a bottle of slick 50 i got on sale. my friends rant and rave about how GREAT it is so i figured i would try it, but i wanted to get a few opinions on here before i throw a quart in my baby. i just ticked 108k... not sure if previous owners have regularly changed oil and/or ever used slick 50 or other additives in the past. last time i changed oil was when i got it, and it was low on oil at the time (if that means anything).... anyone have good/bad slick 50 stories?

p.s. its not regularly low on oil... lost about 0.5 quart in 3-4k miles, not too bad.
