Does anyone know if it has the additive LYCOMING wants for their engines?
I'm a huge believer in Mike Busch Savvy aviator where the only good additive is Cam Guard. Since the multi-grade's will drip off the Cam first after use. The cam guard will protect from non-use. I also switch from multi- grade to strait weight in the summer for more heat protection -YMMV-Does anyone know if it has the additive LYCOMING wants for their engines?
Nothing but Aeroshell 100W Plus and Camguard in my ship.

The only problem with multi is when you need the most protection like take off in the winter the oil is real thin .

Ummm, that's not a problem--that's the purpose of a multi-grade oil. The idea is to add viscosity index improvers (VII) to produce an oil that has a specific viscosity at the engine's operating temp but still flows at startup when temps are cold and the oil has thickened. Remember that the majority of engine wear is at startup so you want an oil that is capable of flow so that it can provide adequate lubrication. IOW, straight grade can be too thick at startup so they add VII's to give it a wider temp range with acceptable viscosity.
This is why some run a straight grade in the summer when startup viscosity isn't an issue and switch to a multi-grade in the winter.
More heat protection?
The multi-weight oil is thicker than the straight weight oil when they are both at elevated temperatures.

I thought running a straight 50 wt aeroshell would be better in the Houston summers over my usual Shell 15-50. Not so.
