Is this true?
Is that what that sweetish smelling blue oil in the yellow bottle Rislone stuff is..ZDDP? Or are you talking about a different Rislone product marked ZDDP?
Never opened one up nor seen it, but it is a yellow bottle looking an awful lot like PYB and it says "The ZDDP additive."

Rislone "Engine Oil Supplement" not the regular oil or engine "Treatment."
It's new. It's on Rislone's website. AAP has it. It's still in a yellow bottle...but bigger size.
Oh okay, so it's a new product! I always wondered what the regular old Rislone engine treatment was supposed to be & do. I guess it'll remain a mystery IDK. Wally's around here just have the original one.
