Running an engine some 3000 RPM below its redline should be absolutely find for extended periods of time. It might “sound” a bit revvy if you run the engine at that RPM when stationary – and indeed it might get hot quite quickly as it will not have the cooling airflow that occurs when driving.

How fast is 3000 rpm in mph?
Thus, at 6800 rpm one is going 1 mile per minute, or 60 mph, approximately. So, 3000 rpm would be about 26 mph. As a rough approximation, add 2 zeroes to the mph to get rpm: 93 mph is about 9300 rpm.
How much RPM is bad?
Incidentally, running at too low rpm can also cause problems, which is why the green zone may be 1500-3000 or 2000 to 3500 etc. Within a certain range, of course more RPMs mean more wear. Especially if your maintenance is based on time or miles. Consider a bearing that has a lifetime of 1,000,000 revolutions.
