Many, many years ago, when windage trays were first being thought about,
but slightly before *I* thought about them, I switched to Mobil 1 in my
FV. The carrousel at RA = "It Done Blowed up". Since it hadn't done
that before, I was inclined to think that oil control with the thinner
oil was more important than it had been with the conventional oil. But
I also quit using Mobil 1 in the Vee.
