Quick edit: I thought the olive oil was used to make up for oxygen, so if you are using a stir plate, not sure the olive oil actually gives you much benefit.
I didn't use a stir-plate as I don't have one. My laziness and lack of a stir-plate (plus a general curiosity) was the reason for adding the olive oil to the starter.
I kept fermentation temps in the low 60's for the most part and slowly ramped it up. Had the krausen excaping the air-lock after a few days in a 6.5 gallon plastic fermenter. First time this has happened for me, so I think the yeast weren't affected by lack of O2 in the brew or starter.
Will see what it tastes like in a few days.
