Why you should check your gas....

To add to the list of jokes about my home state of NJ,.....
The news reported that over 30 cars were stranded on the side of the
road after they filled up at a Lukoil station and received "Bad
Gas".

Now some would think that turning your airplane into a glider in
midair might be better than being stranded in NJ but.....

This raised a few questions for me....Are there any extra safeguards
regarding the delivery and or testing of 100LL before you put the
nozzled in your tank? By draining the gas and looking in the GAT jar
assuming it looks correct, could you still be in risk of having bad
gas? How long would it take for that bad gas to reach the engine?
