I rebuilt everything but the main bearings, pistons, conrods, rings. It had approximately 150,000 miles on it at purchase. The main goal will be to ensure the conrod bearings are not wearing, which should have another 60K miles or more remaining.
The oil analysis from 2 changes after 500 miile 'break-in" with cheap oil are provided here.
I payed for the TBN (Total Base Number) as it is the main indicator of oil ability to counter acid and other combustion by products. The numbers are 4.1 and 3.5, which are very good. The vendor Blackstone Laboratories comments can be seen as well.
Ceratec and Redline 20w-50 are an effective combination at these long intervals for a "track toy" that sees 8K RPM regularly. The Ceratec is at or near the end of life in this application at these mileage points
