Do you change after the 20 min break in or should a guy drive it for a hundred or so miles????

Once a cam is broken in and the oil is changed, is it now okay to run straight syn oil???

Thanks!

i'd change the oil and filter after the initial run in period. this will flush any little bits of junk left over from machining into the filter right away.
maybe use regular oil for the first couple hundred miles to let the rings get broken in, then change to synthetic. altho many brand new engines run synthetic right away.

I run rotella for the cam break in then I drain oil change filter refill with new rotella for 500 miles then I go to Castrol synthetic. works everytime. Im young but a was a grasshopper to a GREAT/Infamous master at one time.....
