Question about Mercury Cars & Trucks
Saw the MIL illuminated (don't know how long). After I looked in the manual, I haven't driven it since. Have appointment on Tues & would kinda like to understand what's being said. Any other options besides $$$? Thanks

Most big chain autoparts stores like Autozone and Oreilly will check it for free and report which codes are present.

I had the samething happen to my Jetta. I took it to the dealer and nothing was wrong.
I would think it's safe to drive until Monday when the VW shop opens.
My 2 cents

Yes it can be caused by low quality fuel, and your gas cap not being installed properly. Best bet is the gas cap, so take it off and screw it back on. Then take your vehicle to autozone and hook up diagnostics to clear your MIL.

The Malfunction Indicator Lamp or MIL (Also called the check engine light or service engine soon light) comes on when the on board computer detects an issue with the operation of the engine or transmission.
The best thing to do is to take the vehicle to an auto parts store like Autozone and have them hook up their scan tool to the vehicle and read the code. They can read it, tell you what it is and also tell you what the code means.
If it is pointing to a faulty component or sensor and you replace or repair the component the the light will go off on its own after the computer sees that the malfunction is no longer present.
You can have the code cleared, but if whatever caused the light to come on in the first place is not addressed then it will just come back on eventually.

The check engine light also called the malfunction indicator comes only when the computer control unit (called the PCM) senses a fault in the electronic controls of the engine and/or the emission system, there are about 200 possible faults that turn the light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen and Autozone parts stores do this testing for free.
