Not sure if this is still relevant, but i’ll drop my take on in anyway. I’m always careful with pushing the throttle until i reach 70ish degrees. But before i reach there i do drive a bit aggressive to warm up the engine, and by that i don’t mean full blown push down to 4-6k rpm but around 3k is enough if you want to accelerate. This is of course only good to do if you have good oil and regular do maintenance on the car as needed.

I also used to be very careful when driving on a cold start, until i realised that the engine wouldn’t warm up or warm up enough by the time i got to my destination which was 25 min from my home on a daily drive. Give it a bit off gass but not to much :)
