just start that bitch up, if it's hesitating buy 4 bottles of octane booster and put it in the tank. what gasoline looses is the octane after it's been in storage. i recomend driving it til the tank empties if you don't wanna drain the tank.

crx88 if the temps are low-colder, gas will maitain the octane level longer. if a car sits for 3-4 months in 90 degree summer weather the octane will get much lower than at the colder temps.

Just use stabalizer when you store it, and then use a drying agent when you start it up. Should be okay. For your proble, just add the drying agent and some stabalizer, and you should be good.

hmmmm I have a car sitting since dec/jan... maybe it's time to change the fuel pump and fuel filter and see if she fires up. I think I have 1/2 to 3/4 tank of 91 octane in her, I was pissed when she cut on me >:(

In either case, you build up condensation in the tanks from heat or moisture, and when it thaws out it gets in to your gas, gas shouldnt sit too long.
