Bad smelling exhaust...
We have a 1990 Dodge Caravan and the exhaust is foul. Not in color, but in smell. It does not smell like regular exhaust at all - I can't describe the smell, but it's like it's burning something it shouldn't be. It is known to burn oil, but that sort of stopped after adding a Stop Smoke additive. Since it has been known to burn oil and the additive is in the oil, could it be burning that instead, causing a bad smell? Could it be related to Ethanol blended gas that is used in this vehicle sometimes?
Thanks for any ideas!

Stop using ethenol which gets way worse gas mileage then regular gas. See if the smell disappears.
Does it smell like rotten eggs?

You might be burning excess oil. How have your oil levels been?
Try running a tank or two of regular gas, and see if it goes away.

Oil burning hasn't been bad since we put in this Stop Smoke stuff. See I was wondering if the Stop Smoke stuff helped the seals and is slowly leaching into the cylinders instead of oil, and the van is burning that?

In many parts of the U.S. the gas contains up to 10% Ethanol. It's posted on the pumps. Does the exhaust smell like rotton eggs? That could be a sign of a failing catalytic converter.

If you still have the Stop Smoke container put a few drops in a spoon and hold it over a burner on your stove to see if it gives off the same smell as it evaporates, it could be whatever is in Stop Smoke creating the odor. Have a nice one. Geo

Could be your catalytic converter burning up. Are you running extra rich.
Also check the timing. if it is retarded it can do this.
I had an 87 same problem.
Is it the Mitsubishi motor ? and what size ?
