Do you guys recommend letting the engine idle down before driving off?

I've always done this. I don't ever warm my cars up by letting them just idle for a long time but I have always let them idle down on their own terms before taking off and kept revs pretty low until the engine is at operating temperature. Do you think there is any benefit to at least let the engine idle down or do you think it's better to just cold start it and immediately start driving before it idles down?

Give it about 30 seconds to a minute. You need time for the oil pressure to come up and for the oil to get sprayed around the engine. You can use the time to check your seat belt, adjust the climate control and entertainment.

@ThreePedalPlow I do exactly what you do. I don't think it hurts anything at all. I like knowing that all the parts are well lubricated.

I've alway gone by the adage to make sure it's warmed up before any spirited driving, that goes for any gas engine. When I was bit younger I had some 2 stroke toys, atvs quads motorcycles. If you didn't warm up your 2 stroke motor it can kill it pretty quickly. Few friends of mine had this happen to them. Killed perfectly good motorcycles by starting then jumping on the gas then dead. Better to safe and get it warm. Can a modern motor probably handle it yes but why take the risk. Just my opinion

1st start of the day in cold temps, I'll idle it until some heat is showing on the gauge. Otherwise I'll just let the fast idle reduce and go.
I'll never cane any engine until it's showing normal driving temps

I always let it idle down atleast, let the fluids cycle through a bit. Id say atleast 2 mins before driving off. Ive known people that just jump in their cars and go which i always cringe at but to each their own lol

Yes, let it come down from fast idle and then what I do is go.....somewhat gently for a bit Watch the oil temp. and when it comes up to what your normal is, it's good to go harder. I'm easy on a cold car. Parts, including the oil haven't come up to operating temps. which is what the car is engineered to run at. Hammering a cold engine is just hell on it, IMO. That's what's worked for me in every single vehicle I've owned. I don't have engine problems either after a long time of car ownership. That's what works for me and it's too late to de-program me on that. :)
