I agree about the debate part. I've been in a photography forum for a number of years and you should see how folks carry on about "to use a protective lens filter" to "not" use one. It's like a religious war, and best avoided .Oh I agree, people become very set in their ways. That's why these oil change threads always turn into a drawn out debate.
I've seen some badly neglected 3.2Ls and I would not recommend changing the oil beyond the factory recommended interval.
Haven't had any Drive-Es yet, but they are newer. If changing the oil every 10k miles is too much of a chore though, buy a Tesla or wait for the recharges to be available.
I only had my '08 V70 for 12 years and 115K. It had the 6-cyl 3.2 and and per the manual, REGULAR oil changes were recommended every 7500 miles. I remember being very surprised when I first heard the engine required nearly 8 Qts of oil! Of course it is a 6 and not a 4-cyl like the current models and European change intervals are longer than in America.
At my first oil change I switched to full synthetic and followed the mfr schedule. I didn't mind going to the dealership because I always have questions about other things and learn much about the various systems and other aspects of the car. These talks also helped build a relationship of trust and confidence. I place a lot on that when I'm having a vehicle maintained that is beyond my ability to repair.
When I traded the car this past summer it was running like a top and I never saw any smoke out the exhaust. I planned to have it for at least 10 years and that was the main reason I went synthetic. I'm sure it will be running much, much longer so long as someone takes care of it. Body and interior were in beautiful shape.
