brad penn oil is great. however a bottle of zddp is easy to put in so not sure why you don't want to? either way your going to have to order something either it be brad penn or zddp
i have been running comps break in oil ever since i got my new motor. i have done about 7 oil changes since then. i have run out of comps additive so i will start using zddp. i used comps break in additive since thats what my builder told me to run. i bought several bottles when i picked up my motor. i am now out and he said zddp will be fine.
I agree. Even easier since the CarQuest in my town now carries ZDDP on the shelf, because enough of us have requested it. Plus they sell it for 7.39 a bottle so can't beat the price either.
