I changed the oil in my 2001 Impala 3.8 and noticed the oil had a gasoline smell.

The fact that the oil level is too high and smells of gasoline suggests that fuel is finding its way into the oil pan - hence the rising oil level ..

On older cars that had a mechanical fuel pump failure of the pump diaphragm allowed fuel to leak internally and into the engine. Your car won't have an old style mechanical fuel pump but the principle is the same - somewhere where your engine oil and fuel can cross paths, they probably have.

Gasoline in the oil would be from a faulty injector or fuel pressure regulator.
You would need to change the oil and check the fuel system for leaks before you drive it.

i would change oil and filter could be dumping fuel maybe an injector

Hi,
If it IS GASOLINE GET IT FIXED ASAP...really! Dangerous to be driving it.
If you confirm it's OIL than get it to a shop and up on their hoist/rack and find out where it's coming from.

Check under the hood on the side of the fuel rail, the fuel pressure regulator value, this is a common problem.

Blown head Gasket or cracked head

your problem is a head gasket youll need to open rad cap run truck rev and see if bubbles come up in rad

plz vote comment reply if you need more help

bad fuel pressure regulator most likely

your converter is plugged

Don't know this car but from the age, I'd start looking for damaged fuel or vapor recovery hoses
