i've had my NOS kit for about 4 months now, only filled the bottle once, and i believe theres still half a tank left in there.

I havent sprayed in 3 months!

How fast do you guys go thru bottles? and where do you usually spray? im thinking of going on the highway just to use up the rest of my bottle

 

I think I waste more showing off Gotta love that purge kit. Only time I spray is when I'm actually racing someone.

 

Well, my bottle heater is always on and i can simply open remote bottle opener. I am always prepared. hehe

I spray when someone provokes me or when I provoke someone..hehe..i went through a bottle every 2 weeks when I first got the kit, but now a bottle can last me 2-3-4 months =)

 

I made that same assumption and ended up nearly ripping what hair I do have on my head off figuring out why the car would not run...empty bottles kill track days...but they do rack up nice slow times in the 1320.

 

the bottle feels heavier than it would empty, and i opened it last time real quick, some nitrous sprayed out, so i think i should still b good

 

10 pound bottle should be 14 lbs empty...get a scale and drop it on there to see what the current (non-scientific) weight is...then you know...if it is less than 18 lbs , spraying with that little in the bottle will not get the pressure up high enough to effect any real change.

 

time to whip out the old bathroom scale
