Just run 1 bottle of SI-1 every oil change will be great.
My Toyota car doesn't like any continuous use of cleaner, but the shock dose of regane/SI-1 give better throttle response after the treatment.
One more thing, driving in higher rpm for longer period or some wide open throttle will help clean faster
