I have a car that has been sitting for a couple years that I'm getting running again. I drained the old gas and put fresh gas in it+ cleaned tank and strainer, etc. I really have no idea of the exact age of the old gas or how to dispose of it, (bought the car not running so 2 years is a guess), I also do not know how to determine condition of gas by looking at it.

It appears darker yellow than the new Chevron 91 that I replaced it with, but still pretty clear. Smells like gas, no horrible varnish smell. Doesn't smell exactly like fresh gas, either, though. Can I mix it in with the new gas and gradually burn it off? Car is a MB 420 SEL w/ CIS, if that matters.

If possible, let's limit responses on this one to actual experience or fuel experts. I can come up with anal-retentive Porsche owner opinions on my own. (Winky face). TIA.
