Blue smoke is oil burning and white smoke is coolant burning. White smoke usually indicates a blown head gasket.

What does Blue Exhaust Smoke mean?

Blue smoke is created by the vehicles engine oil entering a cylinder and being burned along with the Air/Fuel mixture. A small amount of oil leaking into a cylinder will create blue smoke out the tailpipe. Blue smoke is more often and issue in older or higher mileage vehicles.

Sometimes using a thicker oil can help, but in most cases replacing the failed gaskets and seals is the best way to insure the issue is fixed.
