HD top end rebuild
Used this oil for breakin oil on my Road king. Stage 3 upgrade. New big bore cylinders, pistons/rings and cams. No issues motor runs smooth no valve train noise. Change at first 50 miles l, then 250 and 500 miles. For the price and quality this is what I use

The best NON synthetic oil
A bargain for those who do NOT need synthetic oil. I use this in 20+ year old BMW oilheads.

The only thing I put in my Big Dog
I have tried them all and this always makes it run best, smoother feel and it lasts from change to change. It is pricey but it's worth it to me. If you've tried royal purple, red line and others, give this a try.
