Default Blue Smoke from exhaust ??!!!

I know that blue smoke indicates fuel issue, what coukd cause blue smoke out of the exhaust pipes? Car is running 150 miles per tank (15.5 galons 96 Camaro). Is that normal for supercharged stroker? Or is it too rich to run only that much?

Any info wil be greately appreciated.

You're burning oil. Blow-by caused by weak rings can do it. First thing I would do is to run a compression check on every cylinder.

blue smoke is defanetly an oil issue, could be excessive clearance in the valve guides. anyhow blue smoke is an oil issue. check all the possibilities in the oil circuit.

Ok, thanks a lot for clearfing what the blue smoke is. I never did a compression check but it's a built 383 that I bought a while ago, and by the way, the first time I changed oil on it I found some metal sahvings at the bottom of the oil tank when I drained the oil. I did worry me a lot but I never took the engine apart to check what's going on.
What else should I check for that blue smoke.
