IMHO
Draining your old dirty oil then filling it back up with more dirty oil only to drain and fill with new oil was one too many steps and did nothing
Changing your oil frequently is what longevity is about.
I do oil & filter changes every 5000 miles.
Sure I could go longer between changes.....could even send off samples for analysis.
But for me......simple. Change it at 5000 miles and go on.
ALL of my vehicle engines last a LONG time
Oil is the blood, fuel is the heart, air filter is the lungs...keep them clean and all's good
(If I would have used same concept for my body I would be in much better condition but have enjoyed life regardless. 'Rode hard and put away wet' :B )
