So I've understood the crux of what people have mentioned with things such as:
- Let the car run idle for 30-60 seconds and wait for the RPM's to drop (giving time to lubricate all components).
- Drive the car for a while to let oil reach operating temperature, especially before pushing it hard.
- Don't turn off the engine immediately after pushing it hard.
Based on these three things, I have some questions:
1) How long after pushing it hard should you drive before turning it off again?
2) If I drive for a long time, kill the engine for two minutes, then turn the engine back on, are the parts of the car still lubricated with oil? Or do I have to wait for the idle period again? I realize my oil is still at operating temp at this point, obviously.
3) Is there "harm" in turning on your car (on a cold start) to move it very briefly, then turn it off again? I'm talking about 10 seconds of activity. I'm quoting "harm" because people are going to assume I'm overreacting, but I'm asking what the difference is between doing that (when parts haven't lubricated and oil hasn't reached operating temp) versus driving the car for five minutes and not letting the oil reach operating temperature as well, which is an ill-advised plan in the long term.
4) If my oil reaches operating temperature, is there a gradual rate at which I should work toward pushing my car hard? Like if I drive normally for 30 straight minutes and never hit higher than 3.5k RPM, should I slowly work to higher RPM's and higher boost first before doing a straight pull, or if I did a straight pull at that point (immediately go to 20 psi and redline) is all good without having to "work toward it?"
5) Where is the harm hit in turning off the engine if not letting it warm up fully? Is it in turning it off, or is it in leaving it off thereafter? For example, if I’m running errands and my first stop is only three minutes out, but I’m only there for a short while and make multiple trips thereafter (to warm up dat engine), did I “harm” it the same way as I would have if I stayed in that first stop for a while? I guess I just don’t know what exactly is the problem for the oil to not fully be warmed up if you’re not pushing it, and where the actual deterrents lie.
6) I know running the AC will run the engine hotter, but is it okay to “artificially” warm it up that way, or should I let the engine naturally warm up and then do something like run AC?
Then I have a general question related more so to boost that I never really got answered in another thread of mine before: how often should I be using boost in my car? Clearly it's a turbo engine, but could I drive five minutes on a highway in 4th gear with 5 psi and be cool? Or is boost supposed to be a short-term accelerating thing only? How many times in a trip should I be allowed to go above like 15 psi? Like am I limited? This is assuming I'm fully hot-oiled up and such, of course.
Thanks.
