For your engine off coasts down hill what are you doing to take care of your turbo? What I mean is those things get hot while compressing air, and spinning at high RPM and flowing lots of hot exhaust gasses. Then with the engine off for coasting the oil lubricating and cooling the bearings stops flowing and starts to cook off in the high temp of the turbo.

Even if he short filled a whole gallon he is still in the 45mpg range. After a few more tankfulls we may know better how well a saab turbo does.
