I just had my oil changed. Within 10 miles my car immediately started smoking to the point of engulfing the car. I went back to Jiffy Lube and of course they couldn't have done anything to cause this problem. Prior to the oil change my car never smoked or seldom needed any oil added between oil changes. I have added Lucas Heavy Duty Oil Stabilizer. I have driven about 100 miles since adding the Lucas and it has helped marginally. I was able to add the Lucas because the car has burned a quart of oil in about a 100 miles of driving after the oil change. Any ideas and what happened or what is causing this problem?

HI there,

What weight oil did they use and was in mineral or synthetic and is it over full?

A synthetic blend 5W30 was used and I really don't know if it was overfilled. I haven't been in the habit of checking the oil level after having it 'professionally' changed. I will do so in the future however.

Hi there,

I doubt very much that Jiffy lube employ professional qualified mechanics, the oil is correct so I would be checking the dip stick and ensuring that it is not over full.

I also agree that Jiffy Lube probably does not employ experienced mechanics. Would having overfilling with oil have caused my problem? I have no way of proving this was done. Remember in my original question that I stated that my oil level was down about a quart within the first 100 miles of driving after the oil change.

Hi there,

Over filling will cause excessive oil burning, but at it was so low that really does not jell. What I would do is ensure that the level is correct and check the oil in a week's time and see if it is still dropping, I will give it a bit of thought in the meantime, let me know what you find.
