The early 2V seemed to have a period where they were blowing out spark plugs. Not exactly immune to troubles.
Book may call for 5k oil changes but I am doing fine with 10k changes. Based on miles only and now with less use could be a few years between changes. Not an issue IMO.
I would assume all these motors have the exact same oil pump. Oil pumped volume is not an issue.
I had my oil sent to a lab when my Duramax had 30K miles on it. After 15 years it has 95K. They analyzed it and recommended oil change every 6500 miles based on my engine up to that point.
An oil analysis eliminates any guessing and for 30 bucks it's valuable information. As I have repeated many times, regular maintenance using quality products is the best extended
warranty you can buy.
