Hello Scotty, I usually warmup my diesel around 2 minutes daily before driving off gently. I tend to keep it max 2k rpm until coolant is fully warmup. I tend to be fussy about these stuffs but does it really matter? I seen most people start it up and drive like a maniac and rev it up.

I do same. Not only helps engine but transmission also when you allow fluids to warm up before driving hard. Ive read it does extend engine & drivetrain life, sure.

Not really I do the same thing and it has no effect on performance.
