I have noticed that my truck is smoking alot lately. It has been colder lately but not below 15 degrees. My first problem is with white smoke. After long idles it will smoke alot of white smoke for a few minutes. Now i have noticed that when accelerating the truck is smoking (black smoke). I have checked the oil and the level is fine and does not smell like fuel. The only thing that changed was I had my oil changed and switched to synthetic about 2000 miles ago. I now have 5000 miles on my truck any help would appreciated.

it has nothing to do with the synthetic. mine s bone stock with 2500 miles and it smokes white after long idling periods. i think it is normal but my lly doesn't do it at that amount of smoke.

i may look into it further to see what it may be.

I have already changed my oil again and switched to amsoil 15w40 synthetic and also switched from the fram oil filter to a mobile 1 filter for synthetics. It has not smoked from idle (white smoke), nor does it smoke during normal accelaration (black smoke). Dont understand it, the weather is the same but everything is fine now.

White smoke is condensation and black smoke is just diesel smoke. I think all trucks do this when it is cold out, I know mine does.

the smoke i am seeing has a direct connection to sitting idle. it is real thick white smoke and only last a little while. After idling for more than 10 minutes, it won't smoke until you put it in gear and get underway. i can rev it up a couple of times and see no smoke. it almost loooks like when jets are leaving their streaks in the sky.

Ibfarmer,
I believe awhile ago there was information posted on NOT to use fram oil filters. They have a paper in them and can blow apart under cold start-up taking out the engine. Any other fram oil filters you have return them.

On my 05' on cold morning's I pump Whiteish/Blueish smoke LOTS. I'm pretty sure your motor is just to cold in the morning to burn all the fuel so It's unburnt diesel were seeing. Tony who makes the moonshine tune also agree's. I actually made thread on this a couple of days ago. At about 90-110 deg eng temp it's o.k. and the engine drives perfect. Hope this helps.

My truck was doing it no matter what tempature the engine was. Like I said though I pulled in at my home with it still smoking. Changed the oil and the filter, switched from rotella t 5w40 synthetic oil to amsoil 15w40 synthetic oil, and changed the filter from a fram to a mobile 1 synthetic filter, and it hasnt smoke like that since. So dont know, doesnt make since.
