Basically the argument is adding an extremely small amount of olive oil to your cooled wort is just as good if not better then oxygenating. Yeast need oxygen to reproduce and create unsaturated faty acids(UFAs) which help them maintain a strong cell wall. Olive oil is very high in UFAs about 55-85% according to the article. By supplying these to the yeast they can strengthen their cell walls and reproduce w/o having to create their own UFA's and all the sterols as a biproduct. It also helps the yeast create more esters and stabilizes the flavor longer. The amount you need to add for a five gallon batch is miniscule 0.000085mL or 0.085microliters. Unless you have a lab grade pipette you're not going to get it exact. Its suggested that dipping a toothpick in olive oil then into your wort works just fine. The downside to this is a slightly slower fermentation but the final gravity will be the same. This was all tested at New Belgium Brewery on a large scale and I guess has been around for a while but is just getting mainstream notice.
I might try this before dropping $65 on a oxygen regulator.:hmmm:
