Loaded question. Put "zinc" in the search box and study up.
Or buy a race type oil with zinc in it. Like the Joe Gibbs stuff. Or most diesel oils also if zinc loaded. Rotella T is like 1350ppm of zinc.
And when you “study up”, believe the non detergent advice. You can not buy non detergent oil off of the store shelf.

Just send it
Use penn grade or driven. It’s not that costly on Summit
Then reuse it in your boat or old truck.
Or Valvoline VR1, Amsoil, Redline, Mobil1 15W-50. There are several available with lots of ZDDP to protect flat tappet cams. You just might have to put a little more effort into finding them as they might not always be found at parts stores or big boxes.
As Sonny and Cher sang " And The Beat Goes On ". Lol
Where you've got extended warmup times, shell Rotella SAE-30W T-1 Off-Road diesel oil. Tractor Supply Co.
Not break in oil.......
B/in oil is for.....breaking in. You have done that now. B/in oil has different additives.
Select a running oil which has Zn/Ph in it & good to go. I would NOT use separate additive.

Non detergent is for lawnmowers! Just use the zinc fortified oils mentioned and you'll be fine.

Oh OK obviously I misread what the prior poster earlier posted on non detergent oil. (it did sound a bit suspicious!). good info, much appreciated & I will take you guys'
advice. Thank you. RR
advice. Thank you. RR
I use Summit's house brand in my "Buzzin Half Dozen Slant" as my grandson calls it. Quite a few people around this area use it in both go fast motors and stock cruisers. No issues that I know of.

What do you mean by "oil is changed after each session"?

decades ago an experienced racer told me that he changed his oil (& filter iirc) after each Saturday night session & at the time I had just accepted it as gospel thinking how toxic that a dirt track environment must be. it certainly does sound excessive & later someone else has said they changed the oil every time but only the filter after several races. I am open to thoughts/suggestions. RR
