2021 Accord 1.5T. I bought it in December, changed the factory fill in May at about 7500 miles with Castrol Edge 0W-20 & Fram TG. It's now at about 12K, 50% on the MM. The plan is to drive from Chicago to central Florida, so at least 2500 miles round trip, probably 3000 when all is said and done. I'm sure the MM would be fine with a 7500 mile OCI, with plenty of highway miles, but what does BITOG think?
