Whatever time it takes for the normal idle to level off. It takes about a minute and a half for the RPMS to drop from 1200 - 1300 at start to the normal idle of 800 RPMs when warm.

 

according to Al Gore and his G4......you should be arrested for allowing your car to idle more than 10 minutes. you guy's know how many trees you are killing ? awe screw it...let em' run.....it's cold !!

 

The funniest part about the theory is that trees use CO2 for photosynthesis. You'd think running your car would help not hinder tree growth.

Personally I run my cars for about 30 seconds before I drive off taking it easy, it warms up faster that way. Mind you, I don't drive autos so tranny temperature isn't an issue for me. The only exception is when you have frost on the inside of the window.

The Stang won't see snow though, it has a nice cozy bed that doesn't get below 5*C

 

Here's a somewhat related question:

With the 8 liter capacity of the oil pan in the new Coyote motors, I'm wondering how long it truly takes for the oil to get up to operating temperature. The gauges in the car don't seem to take long, but I think those are all "idiot" type gauges that really just show "OK" or "NOT OK" rather than the actual measurements. I ask this question because in my uncle's 2001 Ferrari 360 Modena, it takes roughly 25-30 minutes to get the 11.5 quarts of oil in it up to full temp for driving it all out.

Thoughts?

 

Your temp guage is accurate. It's the oil gauge that is an dummy guage.

 

If you're worried about it then I'd get an aftermarket gauge that shows actual temp numbers and not just dashes. It's not fair to compare the new 5.0 to an older Ferrari motor. Lots of differences in motor design and technology.

 

Only comparison was that both have relatively large oil capacities so would logically take a longer time for that oil to heat up to full operating temperature than in a normal 5 quart car.

Might be older, but I'm going to go out on a limb and say a 10 year old Ferrari motor is as sophisticated as a new Ford one. Not a slam on Ford but when the car costs 5x as much, there's room for more technology.
