Blue smoke

[The_Duke]

Hey guys. Now that it has gotten cold out I have noticed blue smoke at start up. it will put out blue smoke until the engine warms up then absolutely no smoke of any color at all. what could be causing this any ideas?

[The_Duke]

aslo if its warmer out like above freezing it doesnt do it. my oil and filter was done bout 600 miles ago and checked my levels are within specs

Any one have any ideas at all it only does it when cold out and it smokes until its warmed up. its real embarising starting my truck up after sitting and looking like im spraying for misquitos

It's normal, especially if you don't plug the truck in.

it hasnt realy been cold enough here in south jersey i dont think what temp dou you plug yours in. I need to get some kinda timer because I dont wana have it pluged in all night. If a timer is a good Idea how long should it be on before starting any input?

I run Shell Rotella 15w40 year round. I plug mine in when it is 20* or below. It needs to be plugged in 2-4 hours to do any good.

OK I to am running rotella 15-40. I dont think its been been below 20 yet but its been between 20-35 for couple weeks now. Ill plug it in for a few hours in the morning before I start it up to see if it makes a difference; I sure hope it helps

It'll help, might not completely eliminate it but it will be better. Wouldn't hurt running a good fuel additive like Power Service either. Winter blend fuel doesn't burn as good and will cause lower MPG's also.
