What do you guy's do with the unused oil?
 
Since our car requires aprox. 5.5 quarts of oil, we need to buy 6 quarts of oil per oil change. So what do you guy's do with the unused and open .5 quart of oil? I heard oil can go "rancid", especially after the factory packaging has been opened. Is this an old wives tale or truth behind this, and does this only apply to standard oil or to synthetic as well?

Installed an oil cooler so it takes all 6L :D hahahha! I have a ton of half bottles in my room. no idea why I keep them. Yeah it can go "bad" with enough time, applies to all oil

Keep it in the trunk next to the spare tire so I can top off if needed when I'm out.

Keep it for the next oil change. It'll be just fine for a few months in the original packaging.

Few months might be okay.. but I don't drive the car much so I only change to oil every 7.5 month. Nearly 3/4 of a year and the oil will still be fine?

I drain my oil until it starts dripping, close it off, then pour in the extra half quart and let it accumulate for like 5-10 minutes, then open the drain plug again and let it flow out. probably a waste of .5 qt but it makes me feel better to have clean oil rinse through lol

It depends on your conditions but oil has a good shelf life.

Does it really rinse much or just flow right down into the oil pan?

it probably just flows right into the oil pan, but I would like to think it would grab some old oil on its way down lol

Wishful thinking maybe?

You may burn some so keep it for topping off.

You make me faceplam, and question your generation.
Joking aside,

As long as don't store it in an open container, oil will go "rancid" in about 10 years and that if you have oil from the 80's. Today's oil would be good for up to 20 years.
So yeah it's an old myth

Like others said, either keep it in the garage or keep it in the trunk.
