Valvoline Premium Blue Extreme 5W40
Napa Gold Filter
no bypass oil filter
S&B Cold Air Intake
7,591 miles on this sample
This oil sample was 5W40, NOT 15W40.
I'm thinking of running extended oil changes, but wanted some input on this. I typically change out the oil between 7,500-8,000 miles. I ran 15W40 dino oil in the last 3,900 miles and will send that off to Blackstone for testing. I've filled sump with Rotella T6 5W40. Any thoughts?
