As this is your first experience with Flush Out, I recommend that you follow the manufacturer's instructions on the carton. From memory they specify something like ten minutes' running.

Yes, but you may need more than one treatment if they are badly contaminated. Start with one dose of Flush Out before refilling with your chosen 10W40 and see how the engine sounds. If little improvement, repeat the treatment at your next oil change, say after 3,000 miles. That would be my advice.
