Alrighty, goofing off in the shop with a milk frother and some lab beakers.
Left to right, Mobil 5w30 full synthetic, Mobil 0w40 Euro, Supertech 15w40 conventional, Delo 5w40 XSP, and everyone's favorite foam monster............Rotella 5w40.
Added 200ml per beaker and let the foaming begin. Applied milk frother for one minute per beaker. No clue why I started right to left instead of left to right, but it seemed to make sense at the time. Did my best to hold the frother at the level of submergence and angle that produced the most bubbles, but this was never a scientific endeavor and I wasn't about to build some test rig to iron out that variable.
Photos are taken at ~1 min intervals as I try to froth each subsequent oil, and mostly to show the aeration levels in previous beakers.
Rotella:
Delo:
Supertech - This one is an outlier, the frother wasn't able to maintain RPM with the thicker 15w vs. the previous 5w oils. Did the best I could, but if I do this again I'll chuck the frother doodad in my cordless drill and will have plenty of horsepower on hand to maintain RPM even in thick oil.
Mobil 0w40 Euro:
And Mobil 5w30 synthetic.
You can see most of the beakers are pretty evenly aerated, and it's important to keep in mind that the time since frothing goes up by a minute with every step to the right. By the last photo, the Rotella had been sitting for four minutes. The Supertech is noticeably less aerated, again due to the wimpy frother not liking 15w oil.
Next installment to follow.
