STP Oil Treatment

My cam supplier said to run STP rather than any other ZDDP additive.

Blue bottle says it has more ZDDP in it than any other.
 
If you believe the several analyses over at Bob Is The Oil Guy, Lucas is nothing more than ~250 weight oil. There isn't a damn thing in it....virtually nothing except a viscosity increaser.

Schaffers does samples for $9a pop. You can buy the sample box for $54 with 6 jars. They come self addressed. You pull your sample. Fill out the form and put it in the plastic jar. Put it in the mailbox. They can email you results or mail you a sheet.
