the first answer wasexctly what i was goingto say,,,there is no need for it until it gets ear zero anyway if the go plugs are working. there is no " requirement "to use it ever. my 6 started at 15 below without it. long warm ups hurt a diesel more than anything. its better to drive it right off s soon as it starts. unburnt fuel whle "warming up" washes down the cylinder walls and puts raw fuel into the carnk case, not good. it far better to get the combusstion temps up to normal temps as fast as possible while driving easy.

Driving a diesel cold will cause an extreme amount of wear. Especially a truck with a heui injection system you should always let a diesel warm up some before driving unless you want to buy a new engine. Its also extremely hard on the transmision due to the fact the viscosity of atf is different when cold.
You've just responded to a twelve (12) year old post, btw, to a guy who last checked in back in 2010. Just sayin'.

That depends on what ATF you're talking about. That's true for the newer ATFs like MERCON SP. It is NOT true for MERCON (non-synthetic) and MERCON V (semi-synthetic or non-synthetic.)
