Don't use any Aircraft oil in your LT! Actually, not even in a big aircooled V-Twin, which would seem to be a perfect match. They are not.
Aircraft engines are built a lot "looser", and burn considerable oil in normal operation. As much as we kid the Harley riders about their "old technology" engines, they are built quite tight. The aircraft oils are made with various levels of "Ashless-dispersant" capability, with much lower detergent levels than automotive oils. Aircraft engines run typically below 3000 RPM, and for long periods of constant 65-75% power output, and on takeoff quite a few minutes of 100% power, which means they have few "cooling" periods between high power runs. They are constantly burning oil, so have a lot less additives to reduce head/valve buildups.
Yes, go with the Rotella-T.

No bike now, but maybe in the future.
