Question about 1995 Buick Park Avenue
You need to have the trouble code pulled so vehicle can be diagnosed. I suspect the engine is dumping fuel into the oil. If your fuel pressure regulator diaphragm ruptured this would give you the gas in the oil and a rich DTC. You could also have a coolant temp sensor that failed, making the computer think it's -40 degrees and commanding too much fuel-this too would make your oil smell like gas.
Trouble code would help in determining the cause. You can also remove the vacuum hose at the fuel pressure regulator-front left side of engine, on the fuel rail. It should be dry inside vacuum hose, if there is gas, the FPR diaphragm ruptured and more than likely that's the root cause of your problem.
