Thank you for the email.
The Repco 15W-40 CI-4/SL product does not contain any friction modifiers: the boron in the formulation is there as an anti wear agent.

Thanks Alan,
Nice healthy qunatities to keep an engine running clean, but can you tell me is the Boron a dedicated "friction modifier" or anti foaming agent or a cleaning agent or a combination of these ?
Many thanks, Marty
