I mixed about a gallon of gas and kept about half in a closed can.After awhile(2-3 weeks) it changed colour from red to light yellow. Was the oil disolved? How long is it safe to keep gas premix? Should I add more oil?

I keep mix maybe 2 weeks then dump it in the Chevy.

Also depends whether it's stabilized or not.

In Europe gas is over $7 US/Gallon so the smart thing to drive is a DIESEL car/van/truck .(mine gets 42-45 miles/gallon) so no place for gas to dump.Should I just mix less or stabilize it?

Mix less, stabilize, use it up right away; all good ideas.
Just move Calgary back to North America from Europe, we miss it!

I try to run fresh fuel mix all of the time. I always mix with fresh gas and once my mix has got more than 72hrs on it...I generally mix new stuff. I run the saws dry each outing. Now...I'm not recommending that you do what I do (you can definitely use your mix for longer than what I do); in truth your mix should be fine for a few weeks (3). I personally wouldn't go longer than that due to the fact that you have no idea what quality of fuel that you're getting from your gas station to start with. If your just a weekend cutter...mix new stuff each time you head out, what's it really costing you? Health of your saws vs a dollar or two? Oh, and run only premium. My dos centavos!
P.S If you find yourself with quite a bit of fuel mix left over each time...the implied task is to mix less or cut more!

You can tell by the smell

Bingo. It's not uncommon for me to run mix that is 3-6 months old, IF it smells good. I've never had an issue with it personally, maybe I just get really high quality gas from the general store I go to. I've never had a problem with gas less than a year old. Of course I keep my gas in new (less than ten years old) gas cans (made of plastic actually) and those are in a garage which, while unheated, is nice and dry. Makes a big difference. If you store your gas outside with a loose cap, good luck having it last more than a week.

I thought the oil in the mix will wreck your cat con. Otherwise I would dump my month-old mix in the Cherokee and start fresh.

I left a gallon of gas out in the sun in July. Had siphoned it out of my car. I was to poor to afford a proper gas can so put it in a 1 gallon apple juice jug[back before plastic was popular]. I got called away and gas sat in the sun all day. Next day when I came back, gas had changed colors, smell and would not run the lawn mower. Car still ran fine. now all gas is in proper container, stabilized and kept away from all strong light, it is also gingerly sniffed prior to using. I just put 10 gallons of gas in my sons car that I bought in Feb. or early March smelled good and ran good. Don't know if stabilizer had anything to do with it lasting that long but I figure I can live with the cost, even if it doesn't help.
Oh, BTW, My van got parked due to a minor accident till I can fix it last fill up was in early July. Exhaust just doesn't smell quite right when I run it. It is not stabilized.

1/2 gallon or 1 gallon of 50:1 in a 35 gallon tank, in a truck thats 20 years old and gets under 8 mpg. The mix is gone by the time the truck warms up!

I've yet to see a cherokee that gets 8 mpg (except for one that was running 36" super swampers, it got around 10-12mpg). Mine got 18mpg on a regular basis. But you are right, there is no worry about running a bit of mix in your car/truck. It won't mess with the caty at all. I guess it's arguable that it might mess with the caty if you ran mix all the time, and never regular straight gas. But adding a gallon or two of mix once a month, it won't be a problem.
**edit**
And as far as smelling the gas, make sure not to breath too much in, it's not real good for you. I also limit my smelling the gas to only when I'm not sure it's good. No point in smelling it when you know it's fine.

This is from a saw bought new in Feb 07, and he was using the Feb 07
fuel mix, with Stihl oil.
As far as huffing gas fumes, that probably explains my dain bramage........

That fella is either very unlucky or didn't keep his fuel in a proper container housed in a proper location. Although I guess 10 months is quite a while for fuel...but I've burned gas up to 2 years old from a container before (probably not the best idea but it smelled pretty ok, I mixed it with 50% new fuel). I've burned older gas that was sitting in whatever I was working on. Like a weedwacker that had 3 year old gas in it (didn't run long on the old fuel, wouldn't do that again now that I know more about the subject). Much older than that and you're unlikely to even get the thing to fire off.
Basically it's a judgement call. People with poor judgement should just buy new fuel.
