As stiff and rigid and vehicles become when their outdoors in extreme temps,the extra warmup time doesnt hurt a thing.
I feel the same way, I wait till the rpms get to just under 1000 rpms before I do anything. I don't think taking off with a stick shift idling at 1500 rpms or better does a clutch any good. Dropping an auto tranny into Drive or Reverse at the same idle speed isn't to good either. JMO But people are doing it all the time.
I concur!
I also agree, I wait untill the coolant temp meter starts moving. Possibly argued both ways could be using the same amount of gas, if the ECM is richening up the fuel mixture untill 160*f+ or so. Less energy is required to spin a 20lb flywheel, than an entire vehicle?
