I'm the same. My technique, whether for cars, boats, motorcycles, airplanes or
whatever is that when I want to use them I start them up and when done I shut
them off. There might only be slight modifications when it comes to an old
carbureted engine - with a choke on, they don't produce as much power, so
blasting out on the freeway might not work as good as I'd like. And when
shutting off after a really high power run the engine might burp some coolant
unless it is cooled off for a bit. I learned everything from my father, but I
could never quite figure out why he would normally just jump into the car and
go, but if we were going on a long trip he would warm it up first. Couldn't -
and still can't - figure out what "warming it up" actually did. I think
nothing. Idling to warm and engine has no function that I can think of (a
formula 1 engine might be the exception).

Bernard,

At 70 degrees I let my GMC warm up about 3-4 seconds before driving gently
through the neighborhood where the speed limit is 25. I don't like to "stand on
it" or rev the engine up past about 1500 or so until it's at normal temp and
driving slowly with a light load on it seems to make it warm up faster than just
sitting there not moving. In cold temps, like around 35 to 40 (it sometimes gets
that cold in Florida in the winter) I might wait 30 seconds to a minute before
driving.

Since my last name isn't Rockefeller or Trump I try to get as much value from
the gasoline I paid my hard-earned money for. I can't help it that I'm a
cheapskate!

Gary,

I am going to disagree on one point below. Harley EVO engines need to warm
up before you ride them.

A Harley tech rep told me to start the bike, put on your jacket, put on your
helmet, put on your sunglasses, then feel the rocker boxes, if they were
warm put on your gloves and go! If not wait till they were.

He told me failure to do this would result in the forward part of the front
cylinder and the rear part of the rear cylinder scuffing.

Whenever guys would come to me telling me that they were using a lot of oil
I would pull the spark plugs and use my borescope to check those surfaces
and yup they were scuffed.

Regards,
Rob M.
