The big reason for needing ZDDP is for engines with flat tappets.
Last time I checked, no Harley has flat tappets.
Nobody is wearing their engines out by using automotive 20w50 of any brand.
There is no such thing as Mobile 1...

^ and that's why I had to change my rockers and I believe that's where the noise comes from. Also ratblog says that zddp is not the only thing, it's the whole package. He has me rethinking alot. I'm going to try mobile 1, 10-30 in the primary. I wish he tested more 20-50 oils.

I just replaced with new stock ones like these. They only need replaced if pitted out on the end. I had one that was started pitting at 70,some miles, ran them till 110,some before replaced. The one was worse and the other had started. Rollers would of been nice but never heard of anybody on her doing that with stock rods and everything coming out the same. Never really heard anybody talk about roller rockers at all on here.

Here you go: https://www.ebay.com/itm/Benol-Racin...1/302981702025
But I'm not sure what product it is.
Is it castor oil that you can use in your bike for racing?
Or is it the oil you'd use when racing castors?
