Long time lurker here and finally did my first UOA
3000 miles on this 5w-30 kirkland oil. Honda spec'ed this car for 0w-20
I had a few people mention this oil isnt impressive because it sheared to a high 20 weight despite the results being excellent. Shearing didnt result in more wear metals and even blackstone mentioned its harmless.
What do you all think?
Here is how the oil was used:
3 track days. 2 at Thunder hill west(about 95-100 degrees both days) and 1 at Laguna Seca(65 degrees that day)
Lots of short trips where the oil doesnt get to full operating temperature
A...
I used kirkland 5w-30 and it also sheared to levels similar to yours.
