I HAVE A FEW GALLONS OF GAS LEFT OVER FROM VETERANS DAY WEEKEND AND IT IS ALREADY MIXED. IS IT OK TO STILL RUN IT? THANX IN ADVANCE.

I would run it. I usually wait about 6 weeks to ditch old mixed gas.

I'd run it, you should be fine, just shake it up real good

if your worried about it put in a little new gas /w/ pre-mix of course to your old gas . it's ok don't be sceared.

If you are that worried about it I'd run in it my lawnmower it might smoke some but won't hurt it
