The oil remains liquid and will lubricate your metal bits even when very cold. What you are concerned with is the metal bits and how they expand with temperature. This is the thing you want in the normal operating range before giving it some right boot. Moving parts expanded to their normal operating clearances.

Sir, with all respect I do believe you are mistaken. A multigrade oil specified as 5W30 means, its like a 5-grade in Winter and a 30 in summer. This goes back to when multigrade oils were invented, before which you would have to change it twice a year.

Only been in the profession 28 years and I deal with tiny electronics. But that guy - well put it this way, I would have sat a the other end of the lecture room.

Never looked at those things, but go ahead and use it if it suits your purposes. FWIW its easy to say "kills 99.99% of viruses" with no basis in reality. Viruses, even this horrible coronavirus, can survive in water droplets and on surfaces and yes the primary means of transmission is usually by getting onto your mucous membranes (the wet skin inside your nose, around your eyes, in your throat, in your ears, up your urethra, etc) and into your cells where they can replicate. Either through airbourne droplets or on your fingers. But they don't survive outside the body very long. A few days perhaps. Surfaces and those water droplets dry up and the virus particles break down. Cool and damp conditions are kind to them which is one of the reasons why viruses spread more easily in winter conditions. Don't over worry it.

Gaaaa! I can't stand that Engineering Explained you tuber. Patronizing american twerp. As Bret says, once you get a reading from the oil temp display it's OK to consider it warmed up. The water cooling circuit on these engines (you and I have the same) is complex, designed to bring it up to temp quickly for emissions and fuel efficiency reasons.

There is a setting in AA that allows it to pair with a new car. Its in the settings tab (somewhere) and it's off by default.

But how do you stay awake? For motorways I have the "Individual" driving mode set to Eco for engine/DSG and Sport for the steering, and usually but not always the DSG will be in manual and the stop-start will be off.

Eco mode with the DSG is useful in slow moving traffic queues, you get a smoother ride.
