My morning commute is 12 miles on a mixture of A road and motorway and in the time it takes me to get to work [approximately 20 mins] the needle on the temperature gauge is in the centre. The homeward journey takes longer [more traffic] and the needle will have been in the centre of the gauge for a longer period of time.

Thanks to the auxiliary heater, the cabin starts warming up within 5 minutes of leaving home.

Another thing that has a bit of an effect on engine warm up time is the climate control temperature.

If you have the A/C blowing cold air into the cabin the engine will warm up slightly quicker than if you have it blowing warm air into the cabin, due to it taking heat from the engine.

This will also be influenced by the ambient temperature. At colder winter temperatures the auxiliary electric heater will be active, assisting the cabin heating. Leaves a bit more waste heat to warm the engine. Some of remember how slow diesels were to heat without the auxiliary heater elements.

The other factor which is key to heating times, besides temperature, is fuel consumption. You can’t heat the engine fast without higher consumption.

Those who heat fastest must be burning more fuel.

There's a lot to be said for these, although I've yet to have a car with one as effective and quick to heat up as what was fitted to my old Vectra ST200! That thing would be pumping out hot air in a couple of minutes.

It's interesting that the BMW gauge is for oil, I hadn't realised that it wasn't water until this thread. Good knowledge!

Don't do that!

Get in and drive it.

You will knacker your engine doing that too many times.

There was a guy on here who let his engine idle 30 mins each morning to warm up. In the end he had to fork out for a new timing chain!
