A pilot that came into my work told me that a Turbo Oil 2380 is like the best synthetic lubrication oil for the chain (Mind you, this is used for turbine engines). I thought he's bsin so i brushed it off but could this be true? :dunno

2380 is widely used in industrial and aviation. It's a viable possibility, but probably not as good as a PJ1 (or other brand) product that is designed to cling to joints without being slung off or subjected to weather. The internals of engines and turbines don't have to withstand rain.

Ah, that slip my mind about the external weathers. Thanks!
