09 Si and white smoke is coming from exhaust. I have heard that it may be about 8 different things. it doesnt do it all the time jsut rarely. it seems like it may be too much oil maybe? anyone else had to problem of too much oil and it blowing white smoke? havent been able to get a good look at smoke cause its always been on a busy-ish road and i am more worried about getting out of the way. does not do it on start up or when it is in neutral only when i am driving and msotly on a upward incline, i tried some fuel injector cleaner and it ran perfect for a few days then did it again about 3 times in 2 days, last time it did it i heard this pop and then it felt like i had maybe 40 hp. if anyone can give any advice i would love to hear it, been really stressing as not being able to use it is affecting my school and work life.

Could just be normal exhaust condensation burn off.
Any coolant loss?
What does the smoke smell like?

Have someone follow your while driving and do hard acceleations and decelerations..have them note if there's smoke of any sort coming out of tail pipe.

I will try that tomorrow. Smoke kind of smelt like a burning smell was not strong at all. 1st and last time it smoked it was really thick and had some power loss, middle 2/3 times it was barely for a few seconds and very little smoke with no power loss. So far the main thing it seems to be is some kind of issue with some kind of oil somewhere. Was trying to get a few opinions before I take it to a shop. Also, it has almost 140k miles and I have not personally tuned it up except new spark plugs, oil, (and all the other basic things like brakes etc.)
