The price is nice

August 16, 2007

Wow, $2.979 for premium? But I thought the price of crude oil had gone up?

Whatever. I’m still monitoring the results of the new carburetor jetting, and like an idiot forgot to get a receipt the last time I filled the tank. While I usually wait until I’ve used enough gas for the low-fuel light to come on, the gauge is showing about half-full, so I should be able to put about a gallon in the tank.

Or as it turned out, 0.982 gallon.

On the subject of premium vs. regular in a PX engine, the consensus among the folks in Seattle who work on scooter engines is, yeah, you could run it on regular if you wanted, because a 2-stroke engine will burn just about any rotgut gasoline you can feed it.

But over the long haul, if you run the engine at high RPM like I often do, you run a far greater risk of detonation, the knocking/rattling/pinging you’d hear in the engines of cars made before electronic engine management systems (which automatically dial back the engine timing in such situations). You could blow little holes in the little piston, which is not a good thing.

And, as was pointed out frequently, the price difference between a gallon of regular and a gallon of premium is almost always only 20 cents. Kind of a big deal when buying 12-14 gallons at a time for the car, not a big deal at all when you’re buying a gallon and a half for the scooter.

The PX ran well before the Sito Plus upgrade, and it runs even better now. I think keeping things that way is worth an extra 20 pennies. Favicon

    It’s $2.75 for a gallon of premium down here in Texas, Orin. That’s gonna change soon, of course, when we’ve got Hurricane Dean coming right towards us.

    The PX and I will be in Vancouver in two weeks, and according to, a gallon of premium in Burnaby is going for $3.66 ((CDN$1.104/liter * 3.785 liters/gallon) * US$0.94, the exchange rate as of today). So you’re right, things could be worse…
