Thanks Terry for coming back to report a successful outcome.
Since you used
Flush Out followed by a lower viscosity oil than is usual, it is not safe to conclude that the improvement is due to the 5W40 engine oil. It is very likely that you'd have got the same result had you used 10W40.
At the next oil change I'd recommend another dose of
Flush Out to try to eliminate any remaining hydraulic tappet noise. It's the removal of contamination which is important and
Flush Out is specifically intended to achieve that. Don't leave it anywhere near as long as 15,000 miles though will you!
