I'm following suggestions to use 1 qt of EOS on the break-in. I should be firing the motor tomorrow. Do I leave this in for 500 miles, or change the oil and filter after I fire it for 30 minutes?
Thanks

I drained the crankcase and changed the oil filter after breakin. (I used EOS too).

Ditto to what Joe said. I used 2 pints.
