I used to wait for 5 or more minutes until i saw the temp gauge rise to 60c or close. Now i always wait for 30 sec at the very least to a minute and sometimes a bit more while i buckle up, set my gps etc and then drive slowly, generaly shifting at 2k rpm max until the temp gauge is around 60c then shift at 2.5k max when the gauge gets around 80c and then 3k rpm and above when i'm sure that the oil is close to it's operating temperature.
This morning, like always, my girlfriend wasn't very amused at the fact i insisted to wait for a minute until high idle comes down before driving it. (with her Yaris she buckles up etc THEN turn the key, puts it in gear and flogs it not even a second after turning it on and she knows it makes me cringe but she never thinks about doing it the other way around).
Anyway, i always took for granted that you do what's best for your car in the long run and i always cringe when i hear an engine start in the morning then scream at 3k rpm a few seconds later down the road (everyone in my street). I wonder how outdated my thinking is. I always imagine the bypass valve opening fully to give the thick oil a chance to get everywhere but does my "warm up minute" even make the oil really thinner or it doesn't matter as long as oil is flowing everywhere? (i assume not more than a few seconds). What is the most important part, giving the engine some time to warm up or driving slowly like i do? I wonder how much more wear should i expect if i wasn't waiting as much, just turning the engine on, wait 15 sec then drive gently but normally.
UOAs comparing the two driving styles would be interesting. What's your take on this? How do you start driving you cold car in the morning? Any tight high mileage engines driven cold with no warm up time?
