Since your the only one who knows your vehicle, run some MMO for the last 1500 miles till the end of the OCI.
If you think that your vehicle really needs a cleaning.....you could try some Kreen. One pint in the gas and 1 pint in the sump...run that for the summer.
FWIW....my engine, from what I could see from the oil fill hole with the baffle, looked very clean. Then I ran 2 treatments of Kreen and I was shocked at the dirt that Kreen found in the oil galleys, ring pack etc....
IMO...You should know your vehicle best....or if you don't....there are options to use to satisfy your curiosity and clean the engine well.
