Summit Racing oil

Not saying it's a brilliant idea, but....
I broke in my .557 purple shaft solid with a witches brew of diesel oil, OLD very heavy racing oil with lots of zddp in it, and some Lucas breakin additive. Probably had way too much zddp in it. No problems however. Even made a few laps before changing the breakin oil out.
Gonna keep using the diesel, and the old racing oil, cause I have lots of it.
