Old gas looses its octane rating and forms big gooey polymers.
If it really smells like varnish and bad Parmesan cheese you will probably need to drain the tank and change the fuel filters.
If it still smells somewhat good you can probably get away with adding 104+ Octane boost because that will help boost the octane back up and it also contains detergents that will dissolve minor polymer deposits.

Re: how long does it take for gas to 'go bad'. (HatchBox)
my car, 91 civic dx 1.5 dpfi, sat for 3 years. after 3 years, started it up. drove to a gas station and filled up. it ran fine to the gas station. then i drove lot within the next couple days to bring it down to E then i filled it up again. most of the gas should be gone.
i wouldnt do this with a performance motor like a b16 but with a stock sohc motor, its all good
