This has been going on, ON and OFF since I bought the car 2 years ago from my brother. It runs great otherwise. It will just start pumping out a cloud of white to blue-ish smoke and won't stop until I turn the car off and restart it. Most times it does it on the first reset, but not always. Then it is fine for a few months. GREMLIN. Something is sticking,,,,,BUT WHAT??? The car only has 140,000 original miles. Goes through emmissions great but my highway/city MPG is 12.40 as of my fill-up today. Most times it is around 17 MPG. No oil leaks but it is using oil. Any ideas, anyone.Thanks.
