I put a whole bottle of Lucas Stop Leak oil in my '05 Ford Crown Vic followed by 5 qts of oil.

Now, it's smoking out of the tailpipes. It is white smoke that looks like a fire being put out. I've shut the car off and am sitting on the side of the road. I'm afraid to start it back up.

Why could it be smoking?

  • Were you doing an oil change in the car? Why did you add 5 quarts of oil? – Pᴀᴜʟsᴛᴇʀ2 Oct 2 '16 at 2:09
  • No I was just adding oil because it was almost empty from the leak – Dora Free Oct 2 '16 at 2:13

    check the pcv line for oil. when you added the 5 quarts including the 1 qt(?) stop leak was the crankcase completely empty? how's the oil level now? – Ben Oct 2 '16 at 3:30

Did you check the oil level when cold and on a flat surface?

Checking the oil when at normal operating temps will give you an inaccurate reading. The oil needs to be in the pan to check.

If you checked while it was hot and then added too much, you most likely blew the engine.
