1999 C230 Oil smells like gasoline???!?!
A few days ago I changed my oil and noticed a strong smell of gasoline coming from my oil. Changed the oil right away but the smell is still there. I am not sure what to do at this point. 188XXXk miles, maintained regularly and still runs and drives perfect.

Did the oil have gas in it during the oil change? If worried i would drain your oil again to see if there is gas in the oil. There smell of gas might be coming from elsewhere like the fuel system. Look for leaks.

No leaks in the fuel system, the smell is defiantly coming from the oil. The car sat for a couple months prior to me owning it, would that have anything to do with it. Maybe sticky injectors? I'm due for a fill up today, I am going to run some chevron techron through it to see if that may free something up

That’s right you might have an injector leaking. Also check on the fuel pressure regulator, slightly suck on the vacuum port, if it taste gasoline or if there are obvious presence of gasoline you have a broken diaphragm and eventually causes a high pressure build up during idling. It can also cause by incomplete combustion, check the spark plugs and other component associated with it. You may also have a defective TPS switch, but the worst things are worn-out valves or piston rings.
