Ya I'd say two at most within 1000 miles but anything more is a waste. To each his or her own tho. Your build, your money, your practices. I used tbo for like 10 miles and then conventional dynod at 500 @ 2k swapped to tr1 10-40 on my built block NA tho wouldn't recommend waiting on tune with FI. Doesn't use a drop and is 250 across board hot with 4 cranks. Biggest thing is who builds it and what it's used for.

I said common sense kind of inappropriately, because I spent a long time researching and reading practices and articles from mfg.ers and made my own practices not following any one really to a T but what felt right and why.

 

I agree with you but as i had the spare oil which wouldnt be used again i just thought i may as well use it.The best lubrication properties come when the oil is part used...so the viscosity levels come down but the sludge levels havent built up.Too frquent oil changes are counter productive but as you say i dont follew other peoples reccomendatios either,they are for the obdience of fools and the guidence of wise men,so common sense is probably the right description.

 

when I built race bike motors with the same frm tech a decade ago we found if you heat cycle twice then thrash it with a good tune the piston had no carbon past the first ring where as the backup motor got putted around with a slow break in. there was carbon to the oil rings and 10%leakdown the other motor had around 2% just something we noticed which at the time went against Honda recommendations. just some observations from an old bike tech.
