Captain, this is a really good result. I never got a result nearly good with my '03 SpecV.
I do remember my QR25DE was not particular to weight of oil ... and by that I mean I got the best fuel economy while using a mix of Schaeffer 10W30 & 15W40.
My problem was and is frequent short trips of 7 miles then many hours of cool-down before heading back again. I don't think I went much (if any) past 4,000 miles on a drain and they showed signs of a lot of fuel.
(My SpecV UOAs should still be here ... if you search)
I'll be posting a UOA from my new-ish Honda Civic soon ... maybe in a month.
