My poor GTP has been in the garage (maintained at 60* and above) for the past 18 months. It's got a full tank of $2.30 premium 93 fuel.

I'm assuming the gas is stale and I want to siphon it it all out and add some fresh gas before I start the car up to get it over to Triple Edge for some work.

The question I have is, can I siphon out a couple gallons at a time and transfer it over to the wife's Aztek? I don't really want to figure out how to dispose of 17 gallons of old gas.

TIA
