Old Gas
Should be ready to fire up the 454 in the 78 this weekend (said that for about 6 months). Gas in the tank is now almost two years old, but the car's been stored inside the whole time. Can I use it or does it really need to be drained? I think the only additive I put in was a lead supplement when I took it apart in 2004.
Is there a drain plug on the 78 tank?

The gas will burn. It's not a good idea, though. Many of the volitile compounds are gone and it will have a varnish quality to it. Do you really want to risk your 454 over $5 worth of what a couple gallons of new gas would cost? There is no plug, but you can pull the hose off the fuel pump and let it drain out, the put the new gas in it, flush the line with the new gas, hook up the hose and start it up.

I when I took my car off the road and garaged it the gas gauge was between 1/4 of a tank and empty. I left the gas in there so that the blatter in the tank would not dry out. When I fired it up 2 years later all I did was add about 5 gallons of fresh gas and a bottle of Chevron Techron fuel system cleaner and started it up. It ran fine and I never had any problems from the old gas.

Not to be contradictive...but...butt...dont light the gas on the concrete...it will pop and may cause a piece of debris in your eyes...or maybe teach a kid to light his dads drive-way on fire.
"I saw Mr.Bob do it!"
The idea of killing the grass is good though...dont get caught by tree huggers.
For best effects...pour it on fire ant mounds, or ground hornets and light it...it lasts longer.
