IF you have a car that was being filled with sythetic oil, is it bad tyo change to regular oil on the next oil change?

Depends on the mileage . On cars with little or no miles(35k or less) no there isnt any concern . with high mile cars/trucks(100k+) yes it could be a problem , as syn oil cleans more and could actually cause the car to use more oil as it cleans out the sludge the motor has accumulated over its service span .

That is a worry when chaning from Dino oil to Syn, not the other way arround.
