I need the knowledge of the engine experts on this forum....
Every vehicle I’ve owned in the past has had higher RPMs upon cold startup. After about 30-45 seconds the RPMs would reduce down to a “normal” idle speed.
I’ve always made it a practice to start the engine, wait for the RPMs to lower, and then place the vehicle into gear to drive. I remember being told that this was best for the engine.
The Ascent seems to run almost two minutes at higher idle speed before slowing down. Outdoor temps in our area have been in the 70s and the vehicle AC has been on - not sure if those factors make any difference.
So my questions are 1) is it “normal” for the Ascent to take so long to come to a regular idle speed? 2) should I wait until it comes to a regular idle speed before placing into gear? 3) would I be doing any long-term harm by only waiting a few seconds (say 30) after startup before driving?
It seems I would be wasting lots of gas over time if I always need to wait for the RPMs to slow down.
Thanks for the knowledge.
