Brad-Penn racing oil, SAE-30 break in oil is one of the higher levels of ZDDP additives.
Once the engine is broke in use there multi grade oils which also have the higher levels of ZDDP additive.
This is the thick green oil like the old Kendal oil was,
from what I can tell the Brad-Penn oil is made it the old kendel refinery, I used this stuff in my 428 break in and had no problems.
Then after it's drained out of your engine use it in your lawn mower, snow blower ect.
