Why on earth was the thermostat not put back in (or a new one - they are under a tenner)?
It will use a LOT more fuel without it as the engine can not reach operating temp.

perhaps he thought it may well overheat and cause another HG to blow?
The only reason I know of leaving out Thermostats is to hide an overheating problem when you flog a dog!

Some mechanics are lazy or might not have done the job properly in the first place and want to hide their mistakes. Whichever it is - probably the lazy bit, this is the root of your problem as a cold engine will use a lot more fuel - essentially the ecu is being told through the coolant temp sensor that the engine is in warm up cycle and more fuel is needed. You need to get the thermostat put back in so that the engine can get up to temperature - you might be grateful of it in the winter as well!!!
