How long should you let your car warm up for before driving?

I wait till the temp get’s half way to runing temp. I never rev above 3500rpm until my engine gets to running temperature

I start the car and go immediately after. Even when its -20 celsius

I think the best thing is to start driving after a few seconds, as letting the car warm up while idling is bad for an engine too. And when you drive (even if it is rather slowly) your engine gets to it’s operating temperature much faster.

When the engine is cold I don’t let it go over 3000/3500 RPM’s (with a normal gasoline engine with a redline of at least 6000RPM, with diesel engines I would keep it lower), and I don’t put the pedal down more than about 30/40% when the engine is cold. As a high load with low RPM’s also makes the engine work rather hard.

Keep in mind that when the engine temperature gauge gets on it’s normal position, it doesn’t necessary means that the whole engine is on the correct operating temperature. There still could be parts of the engine that need to heat up more to get to their proper operating temperature. So it’s best to even at that point at least wait a few minutes before you go blasting full throttle.

I turn it on. Have a smoke, get in and take it easy for a couple of miles until the temperature is normal then I accelerate hard.

About a minute in idle seems to be good. Then just change gears at low revs for a few miles until the car has warmed up. Make sure you use a good quality oil in the winter to help look after the cold internal components. (I usually do an oil change when it comes to the end of summer to make sure everything is all good for the winter months.

I at least let it idle for a minute or two, so that oil surely makes it way throughout the valve train. Then I just take it easy until it’s at normal operating temp. If I’m going to drive aggressively, I head to the back roads anyway, which is about a 15-20 minute drive.

I put the key in, turn it to last step before launching because on diesels there’s a spiral light, (some kind of diesel spark plugs) that must heat up, in summer it didn’t turn at all, now it turns, from 1 to 10 -15 seconds, in winter maybe a minute, and after go. Also when I launch first 10 min I don’t shift higher than 2500rpm.

Usually for about a minute or 2, just until the engine starts to spin at about 1250-1100 rpm, or when I don’t have time, about 30 secs, but I will not use the throttle until the engine is warmed up.

You can start driving right away imo but just be calm, don’t floor it from the beginning.

I drive it for around 14-15km not higher than 2000-2500 rpm. After that I will go 5km under 4500-5000 rpm. After that the engine/oil should be warm enough and working fine. (mind you this is on my Nissan with the Revlimiter somewhere around 7000-7200 rpm. If yours is lower you should keep the rpms during warmup a little lower)
