Hello. I'm a first timer so pardon my descriptions.

When I start my engine from long periods of rest (overnight mostly), it fills up the place with visible smoke and then ceases to do so after about a minute, two max of idling. This is rather troubling as it only did this twice or thrice a week but ever since I had a mechanic change my engine oil and leaky top engine seal, it's become an everyday issue. It can get rather embarrassing.

Good morning,

What color is the smoke?

White is burning coolant.

Blue is oil.

Black is excessive fuel.

Hey. The smoke is blue in color from the examples you sent me. The engine oil dipstick shows my oil change is actually on the high point. Could this be the problem?

No, most likely it is valve seals. When they are bad, oil goes down the stem of the intake valve and settles into the cylinder on an overnight sit.

When you start it up, the oil burns off and does not smoke again until the next start with a long sit time.

This was very helpful. So I should get the valve seals replaced by a certain mechanic?
Also I noticed when I drive without the A/C on, my accelerator and general vehicle response is quick but then when I turn the A/C on, it almost feels like it bogs it down.

My question is, should this be something worrisome? As I honestly just became a Nissan Rogue user and I'm not used to a number of things. Used to use a Honda before now.

Okay, I would have the oil changed and install a heavier grade oil installed. That could very well stop smoking.

If you do not use any oil between changes, I would not do anything unless you start using oil.

Any shop can do this for you.

Heavier grade oil might fix the smoke. Noted thanks. But that doesn't explain the way the engine feels lighter without the air conditioner on.

The vehicle response is much better. I hit the accelerator and I'm off like a cheetah. But soon as the air condition is turned on, it feels like a totally different car. I need much more throttle push to get it moving. Sometimes I feel like I'll break something. That's how much laggy it becomes.

I can only deal with 1 subject per question as per the site rules.

If you would go back to the beginning and start a new question, I would be glad to keep working with you.
