Interesting question. I will have to admit I almost "never" switch to crossfeed. My thinking is the "only" time I'd use crossfeed is in a single engine emergency. Right? Or are there other appropriate times to use.
In my three previous aircraft, all Cessna singles, I've always lived in somewhat trepidation of the fuel selector. Not wanting to have it malfunction I've never liked to play with them much. So that's carried over now to the Seneca.
However, I can appreciate that I should probably "exercise" it more often than I do so the capability is available to me in case of a single engine failure.
Where/how does yours leak?
