Time To Reach Normal Temperature

was wondering how long does it normally take for a 1.8 tddi diesel focus to reach normal temperature (temp gauge in middle position) from cold. I go for about 8 miles in this cold weather before the needle is in mid position.

My previous petrol cars took about 3 miles.

Mine takes about that time/distance too, all previous diesels I owned always took longer to warm up than petrol cars (so it also took longer for the heater to get warm too!)

I think it's a characteristic of diesel engines - one reason they're more economical is that less of the energy they produce is wasted as heat.

I heard it was also down to the diesel engines being cast iron, not aluminium, so it takes longer to warm up...

Pass... i dont know enough about this engine yet lol!

ours might be, but i know the older ones were cast iron or something suitably heavy, and I remember being told that was one of the reasons for the slow warm up.... but i can also believe the efficiency side of things, which makes perfect sense! lol

Have to agree it takes longer due to diesels running cooler when the outside temp realy drops it can take longer as the thermostat barely opens when it does its being cooled by the rad straight away
