RS-R RAN-UP oil additive

[ck-GT86]

I got a bottle of this, seems to work just fine. Just switched to E85 so it's a little hard to tell how effective it is.

Yeah that's true. Instructions say it's good for two oil changes. Everyone seems to be putting I full bottle- dev RSR in original post

What does an oil additive have to do with ECU programming? Did the additive magically change the ECU targets for idle speed?

There's less friction, so the engine spins slower?

Smells like snake oil, sounds like snake oil and costs about what snake oil normally costs.

Has anyone sent their oil to blackstone for analysis after using this stuff?

Any updated before/after dynos with the rsr additive?
