Cold engine accelerating?
Hey guys. I have realized something. Yesterday i had to go to a friends house real quick, i started my car that was cold and left. I drove fairly easy then about 10 minutes later i got a call from my friend that he was at my house instead. So i turned around and went back. The thing is when i went i went back i went back at a fairly "high"speed and the car was almost at its full operating temp, not fully though. The thing is I'm afraid i did some damage to the engine by doing this. Anyway i know im going to catch flack but thats fine, but in your guys opinion did i do some major damage or am i trippin? Anyway thanks in advance guys!!

Your right, it wasn't the best thing to do. i take way more care of my car and generally don't do something as careless as what i did yesterday, but i kinda had no choice. Do you think this warrants a trip to the dealer? Just to be safe?

I think it's fine we've all done this time to time despite not the best thing for the car. I think your dealer may not take you seriously....

Lmfao! this wouldn't be the first time the dealer doesn't take me seriously. Being 19 doesn't help that either. :/ but you are right, i would sound a bit ridiculous if i took my car in for this.

In 10 minutes your engine is at full operating temperature unless you were somewhere at -20 temperature, where it takes a bit time but even there after the car has been driven for 10 minutes it is warm enougfh to do what it can without causing any damage.

I don't know what kinda engine you have NA or twin turbo . Turbo engine needs to idle a few seconds before shutting it off because of turbo turbines.Because these turbines keep running on even when you stop abruptly and these remain running w/o getting oiled if you turn your engine off w/o idling ,in long term you may end up turbo failure.
This is why I turn off ECO when I do use the buttons behind the steering wheel and come close traffic lights .
These engines are warmed up quickly then other engines to optimize fuel efficiency and catalytic converters' doing it's job as well
