Once upon a time, I saw a video maybe on youtube. It showed a cool effect when pouring Mobil 1 into a funnel: Once the funnel is coated with Mobil 1, stopped pouring and let individual drops fall from the bottle onto the funnel and the drops would shoot down the surface on top of the layer oil coating the plastic funnel, like BB's.
Maybe any synthetic oil can probably put on this droplet show. I was reminded of it the other day as I was pouring Mobil 1 4T into my Ducati. Sure enough, when each bottle was depleted and dripping drops, the drops shot down the funnel like little fluid BB's.
Can't find the old video, no longer on Youtube.
