Increased oil consumption at ~65K miles?

Lasted only maybe a minute or so, but she was so close to stalling that I didn't wait to see if the issue self-corrected: I goosed the gas a little, and as soon as I did the engine smoothed out and the voltage went back to 14.

I'll bring it back to the same shop next weekend; I can't get there today/sooner. Again, both for continuity and because if they didn't tighten something properly (or whatever) I won't pay for the fix.

*sigh*
