maybe but i just started to notice puffs of black smoke on start up really noticed after i started useing powerservice ( white bottle) is this normal or something to be concerned

 

I would personally say no to worry about the smoke problem. Keep an eye on the oil level, and coolant level, you should be fine. Does it start good and quick as normal?
I remembered the first time I started mine in the winter, I worried about the smoke but not now, I keep an eye on things and no longer worry about things.
Does the smoke clear away after a few minutes?

 

just started ( that i noticed ) in the last week or so starts good and runs good still but just happen to notice it a couple times and wanted to check
it is just a small puff then it is gone


thanks for the input though

 

I wouldn't worry about it at all, truck in my sig does it to and I think it's cool.
