Looking for some advice on my ’13 Versa sedan…When the car has been sitting overnight and I go to start it the next morning, I see a pretty full stream of white exhaust (definitely more than normal) for about 15-30 seconds and returns back to normal. During the 15-30 seconds, there is a super strong smell of gas…Once the smoke dissipates, the smell dissipates as well. The engine bay does not smell of gas…And there is no smell of gas around the gas tank/cap. Another thing to note, my gas mileage has been less than average. As I have mentioned in a previous post, my engine revs higher than it has in the past. I’m lucky to get about 430 km’s to a tank which is about 267 miles. The car has about 75,000 miles on it.
