Then you may have a bigger problem. Like previously mention Oil burning isn't a great sign.

What's the car? Model etc. What fuel are you using?

Another alternative is contaminated fuel.

I would suggest switching to either E10 Ethanol or 95/98RON. 89 is absolute rubbish. It's the worst thing you could so to your car.

In a saying that, that smoke could be something else. Without being there I can't really smell what's coming out.

There is a reason why the 95/98 is more expensive. In the long run it saves you money as it keeps the engine in optimal condition!

A prime example is if you eat McDonalds everyday, you'll eventually get sick! It won't happen straight away but you kill your self. Eating healthy is the key. Same for the engine. Feed it right. This car or next.

89 (R+M) in America is equivalent to 94-95 RON, and is frequently E15 but almost always at least E10. 87 (R+M) is 91-92 and is almost always E10. 91 (R+M) is 95-99 RON and will either be E10 or E0 depending on how much extra you pay. E0 costs significantly more.
