During the winter i usually wait for my motor to warm up to its normal operating temp before i have a little fun. I always let it warm up because thats just what i heard you are suppose to do. Well the other day i nailed the throttle as i was getting onto the highway and i didnt let my motor warm up. it just completely slipped my mind, i was in a bit of a hurry. I noticed the acceleration wasn't as quick as it usually is when the motor is warmed up.

So my question is... Do people let their motor warm up because the car wont go as fast if they dont let it warm up or is it actually bad for your motor to nail the throttle when its not warmed up?

My Mom of all people told me about 30 years ago that the The purpose of warming up your car on cold days is to warm the oil so it is flowing smoothly into all areas of the engine before you over power it. Really cold days can make for slow flow. now my mom's no mechanic but it always made sense to me.

Letting a motor warm up allows oils to circulate and the tolerance to tighten. Metal expands when warn making the tolerances tighter. Hotrodding a cold engine means you are hotrodding a motor that has ever so slight larger tolerances in rod bearing gaps, etc. Greater tolerances means that the rods are hammering the crank ever so slightly harder. It nothing to worry about once or twice, but over time it causes increased wear.

I learned from my own experiences....every car before the mustang i could turn the key and romp on it...not discrediting the mustang by any means, but on my current junk yard motor i have to wait for the engine to warm up. I blew my old motor due to a faulty PCM module, ended up swapping with a motor from a boneyard that supposedly had about 80k on it.

With this used engine i have to take it light till the engine gets warmed up...its in the early signs of a lash adjuster going bad...if the engine is cold and i romp on it, i get a stuck lash adjuster and bad problems...but if i let the engine warm up, i can romp on it all i want

That's fun. My mother told me something very similar, not my dad.
