Long term impact of repeated short trips?
#16
In a related question, how about after the engine is fully warmed up?…will idling a long time also damage the engine? I ask cause in the winter, when taking the car to a self serve wash, sometimes the line is long and you have to sit idle for a long time before it’s your turn to wash the salt off the car, and too cold to just turn off the engine.

Exactly, and that's why I started this thread - to educate myself and figure out if I should change driving 'behavior' when possible. There's so much knowledge on this board, it's a great resource.

I don't mean to hijack this thread, but I think my question is pertinent..
I've noticed that the PDK short-shifts extremely in normal mode - a steady 40 mph goes to 7th gear!
Yes, I do realize that not a lot of torque is needed just to keep steady, and that the PDK knows best etc.. But what about cold temps?
I know it's probably not lugging the engine when cold, but coming from a 997 6spd, it feels like the rpms are way too low and that the warmup is taking longer
So in cold start warm up periods, I shift manually and keep the revs around 2500-3000 rpm, except when it comes to stop-go (1st gear territory) and I switch it to auto then.
I'm still peeved by the rattles it occasionally makes during the cold runs until warmed up.
I haven't compared the warmup times of auto vs manual - but I like to believe that it warms up faster when I shift manually and keep revs near 3000 rpm (than auto that keeps to 2k rpm).
What are your thoughts on this?
