[Shrek] Learn Something New Every Day

One of my goals in life is to learn something new every day. There is an adage that says "all knowledge is worth knowing", and I firmly believe that's true. Sure, some of the stuff we learn is worthless unless we're playing Trivial Pursuit, but in general having a wide base of knowledge is a good thing. For me, learning something new when you least expect it is the best...and that's what happened to Fiona and I Friday afternoon.

We were heading out to the Super Walmart in Leicester after work when our "low fuel" light came on. We were planning on stopping for gas anyway, but the idiot light served as a good reminder for us to not forget. As we pulled into the gas station, we saw a man filling what looked to be milk cans with gas. It turns out the man was an inspector for Irving Oil (the company who owned the gas station), measuring the pumps to make sure they were dispensing the correct amount of gas.

We've all seen the stickers on the pumps certifying they pump the correct amounts, but who here has ever seen someone actually checking them? It seems Irving Oil checks every pump once a quarter, while the state only checks once a year.

It turns out there's more than one test. First they check to make sure it pumps exactly one gallon by, you guessed it, filling it to a line in the can at one gallon. That part seemed obvious enough. But then they weigh it, and depending on the temperature and humidity (I'm pretty sure he said humidity), it has to match what the chart says it should weight, within 2 grams. Then on top of that, they do it again, this time using a two gallon measurement. They do that for every octane the fuel pump dispenses.

Fiona asked the guy why hardly anyone ever sees this being done, and he replied that it's usually done on Sunday mornings when traffic is light, but because the weather was going to be so nice he wanted to get the job done as early as possible so he could enjoy the weekend with his family.

So the next time you're out on an early Sunday morning, take a peak at your local filling station to see of you spot the guy with the milk cans. At least you'll know what he's doing. Oh, and how often to pumps fail the measuring test? According to the guy, unless they're tampered with, just about never.

So I guess that's two things I learned on Friday.
