mk4 golf temp probs

im confused with this me mk4 20vt doesnt heat up fully obviously new stat needed probs sticky or crudded up but im still seeing 386miles from the tank and averaging 35-42mpg now surly if its not heating up fully the choke would be sticking open to allow more fuel threw for a cold engine

oh n the temp im gettin is just below 70 any suggestion would be good

mines doing the same mate its the colder air i think meaning a more rich mixture of fuel being used. In fitting a new thermostat to mine.

sure your not just used to it always being at that temperature? there isnt a huge difference in the fuel mix between the temps its getting to and the temp it should be at but if you put a new stat in it will most likely do more to the gallon.

tiz it usually sits just off 90(80-90) not on 70 thats y im questioning it mate

or would this be the weather effects to
