Fred was just in shop looking around contemplating life and I looked at this and wondered if you knew about it. This oil has all the bad stuff in it zinc, lead etc. having a flat tappet cam it is a requirement. But modern oils don’t have the same lubricating qualities for your bearings either. My pal with the wheel standing scamp has been reving that 340 to 7500 rpm for 10 years and never had the bottom end apart. Mind you that only happens 8 times a year but still. It’s what I use expensive but I believe in it because that’s what was used before the tree huggers messed it up
