Puzzler. I'm going to guess a leaking head gasket. This is the gasket that sits between the engine block where the pistons are and the cylinder head where the valves are. Coolant passes through it and it's exposed to the high temps and pressures inside the combustion chambers. When this gasket blows, the engine still runs but efficiency can go way down, allowing coolant to leak into the cylinders, where it would burn off rather than pooling on the ground.
Not too bad to fix, cheap parts but labor intensive. Maybe 3 hours + $100 in parts?
Interesting. They took a look at it (parked, not on the lift, but still using mirrors) and didn't see anything. They were looking for leaking fluid though.
What we did find when we plugged in the computer was that a Crankshaft sensor circuit was broken. This part controls the amount of gas getting fed, based on the crankshaft speed (at least that's what I understood). So, he's either going to fix it or replace it.
