Engine temp question

[Golf4]

Hi guys, curious on this topic as I put the 'slowness' for my engine to warm up down to the cool weather. I have also noted when at freeway speed the engine will not hit 90c and can actually drop back a fair bit from city driving temp.
It will still hit 90c but definitely takes longer with this weather - I'm just debating whether to get the thermostat done....not made of money and this car has been eating it up recently. If its going to improve economy then I'm almost convinced.

I did the thermostat replacement on my MKIV 1.6 only a week ago. Took an hour and $19 for the thermostat. If you are at all mechanically minded you should be able to do it your self.

Well the mechanic replaced the thermostat and it's running fine again. $40 for the thermostat plus labour and a bit of coolant meant it was cheaper than I expected
