Why doesn't Kirkland synthetic oil put a mileage rating on it?

Space is limited. I assume Costco doesn’t want to add more choices being the markup on oil is low compared to higher profit items where general merchandise is sold.

Just saw high mileage version of 5w30 at my local Cisco few days ago. Probably will pick it up for my Hondas when it goes in sale

Been using Kirkland 5-30 syn in a 2005 Pontiac Vibe the last 10 years, I changed the oil once a year which averages between 8000-10000 miles per year, the car has 280,000 k miles , it's doesn't burn a drop of oil and the motor runs excellent, this is a great oil at a great price
