I would use straight 30w oil and a bottle of gm eos for break in. Change the filter only after the 20 to 30 min run in time. Then, add 30 w to full mark. Then, run engine with break in "package" for a while longer.
I`m not a "break in oil" advocate as a special high dollar oil.
Then, drop oil and filter and run what you want. Been working for 30 yrs or so.
