All mileage is in kilometers not miles.
Notes from oil slip: "Upgraded oil cooler plus 12 hours of track. Did short M1 5W-30 before this one to wash out old oil. Went to M1 due to price. Is this oil bad?"
Switched to Mobil 1 15W50 since it's much cheaper at Walmart. Previous fill was a short OCI of M1 5W-30 of street use only.
