Break in oil any suggestions on brands

Brad Penn. Just bought 12qts 30wt break in oil and 12qts 10w30 at a machine shop I came asross for $140

WOW.... That is expensive. A local engine shop sells Brad Penn for $6.50 a qt. Just bought 6 qts of the 30 wt break in oil for $39 + tax. Bought 6 qts of Brad Penn 10w40 for same price, for after break in.
