I used to be that guy.....dumping $12 qt oil. Regardless, I still would not have dumped it out till at least 5-6K miles, given driving/operating conditions.

Oil has come a long way...the TI oil is along the lines of HM oil, loaded with ZDDP...

Hell, if I was the OP and was giving it long hot runs, I would not even squeam at changing it every 3 years, without even giving it a second thought.

Granted oil is cheap, so if you've got the time or dime, do whatever makes you comfortable
