I use Polaris VES in my 14 Pro. I will be doing a rebuild soon. Building car/truck motors it isn’t suggested to use synthetic oil for break in. So, what oil should be used to break in my motor?? Should I empty the VES out of the oil tank and replace with the real cheap conventional oil? Or should I keep the VES in the oil tank and add some conventional oil to the gas? Or should I just break it in on VES oil?
