Viscosity of STP

[GreeCguy]

Howdy oily gang!
Could somebody tell me the viscosity of STP or link me to a discussion of that topic? I read somewhere that Molekule did a thread on it but I can't find it -
Thanks

No time to look for links right now, but there was a good discussion of it in the Additives forum. I believe it was on the STP 4 cylinder treatment. IIRC the company reps have said 500cSt for the regular STP and 100 or 200 for the 4 cylinder stuff. There is a VOA on the 4 cylinder stuff at this site and it shows close to 100 cSt IIRC. You probably are better off with Valvoline Synpower Oil Treatment, though twice the cost (also a recent VOA on this site for it).

Take a look in the VOA Library it's in there....
