My 03 G35 sat for 2-3 years without driving it at all. It was practically on E last time I drove it around. Should I have the gas drained or just fill it up and put some fuel cleaner in it?

 

drain everything ! refill new, youll have better piece of mind knowing youve covered every track to reduce variables even though things might not need it. might !

 

Like jutn posted I'd drain/fill everything, gas/oil/trans/powersteering/brakes. Then you won't be telling yourself in a few weeks, "Wish I don't what they suggested!" After you've done the drain/fill add a bottle of RedLine fuel injector cleaner and maybe again at your next oil change....Gary

 

Why didn't you add some fuel extender and fill the tank when you left the car?
