I know the rule is to start the car, let it idle for a short time and drive slowly till the engine warms up. I've also read this will cause the least wear as well ...
2 of my cars one with over 200K (V6 MPFI) and the other fairly new (V8 MPFI) both make some odd sounds (ticking, knocking?, etc.) when the rpm gets near 2000 or 2200 if I drive them cold. But when they are idling (700-1200RPM) they both sound very fine especially the new car.
With the new car, i typically wait till the engine coolant is near 140-160°F and then drive. With the old car I don't care as much but try to wait for 100-120°F.
The new car doesn't make as much (or as loud) noise as the old car but If I let it warm-up and drive , it sounds super smooth. I was surprised that the new car makes similar sounds when driving cold.
it's also an old habit to let it warm-up but every time I try to follow the recommended guideline (start and drive slowly) I hear the noises (not in my head lol). Maybe the noises are nothing to be concerned about but as a result, I'm sticking with the old fashioned warm-up ...
curious if you guys notice the same noises when driving cold?
