Many of you seem to forget that you
REALLY don't
ever want to run out of gas in your Spyder, as doing that
WILL damage things; and even if you are lucky enough to avoid your engine needing expensive repairs (or maybe scrapping)
now, the damage caused by running out of gas, or maybe even just running low on gas,
is irreversible, cumulative, and in the majority of instances, ultimately terminal! 
You always
NEED to have at least a couple of litres of gas remaining in your tank, as the fuel system uses that remaining fuel as both coolant and lubricant, and all the damaging contaminants end up in the bottom of the tank, meaning that if you get down too low in the gas remaining, bad things will start to happen to your engine, or maybe even happen now! So if you
think you could've still run for about another 50 miles on what gas was remaining in the tank, that's about your last opportunity to safely fill if you don't want to damage things! Anything much less than that is getting pretty risky!
There's a lot more discussion on this that's already been posted here on the Forum, so I won't re-iterate it, Search is your friend; but seriously, don't be the sucker who continually runs their tank down to empty or even almost empty; you should definitely be starting looking to fill up by the time it hits about 1/4 of a tank remaining, and if you're looking at buying a used Spyder, don't be the poor sap who buys a Spyder that's run out or been run down too low in the gas remaining too often! I'd suggest steering well clear of one that the seller admits has
ever been run dry!
Just Sayin' - Again!!
