[G.A.S.]

I am from the old school and I say warm-er-up......
I know with all the modern, upgraded, fuel injected, individual coils, map sensored technoligy A car should run hot or cold from start up to warm up to shut down, but what about the oil, engine block itself.
There is no way I would get into my newer blazer, start it in 15deg. weather, drop er in gear and go.
I dont care if your the man that built the car telling me I can do this.
It Needs to be run for at the least 2-3 min for the block to start to warm up and the oil to warm and flow more freely.
This is just my opinion.
But,......... I would like to see the inside of my engine and your engine at the same millage if we both did it our way.
Think of it this way.
Metal expands when getting warmer right.
P.S.
I bought a remote starter to help keep them nads warm. No walking to the z twice.
