So... a number of articles out there now state warming your vehicle before driving is bad because modern engines compensate for colder temps by adding extra fuel to the mixture, which will in turn dilute your oil and add wear and tear to the cylinders, cylinder walls, rings, etc. by idling for too long without driving.
Other articles state you do need to allow warming since the oil has all drained into the pan is more molasses-like. It needs to warm to become less viscous and circulate properly. Add the fact that cold, unexpanded (near) metal on metal interaction would seem to add wear and tear.
Now, my childhood was during the transition from carbureted engines to EFI. I was taught that you need to allow your vehicle some time to warm up before driving. I still tend to believe that. A car that has idled for a few minutes runs and shifts smooth like it's supposed to. I let my cars idle before driving - 5 to 10 minutes in cold temps and 2 to 4 minutes in warm/hot temps.
So what's the ODT consensus? (A) Yes, it's bad to let it warm up? (B) No it's fine? (C) Doesn't make **** for difference?
