#0835: Whose Gas is it, Anyway?

Original Air Date: 08.30.2008

   Best Moment

This week on Car Talk, we wade into the seldom-charted waters of gas pump etiquette. Heidi's got a nifty maneuver to get the last few drops out of her hose, but was alarmed to learn she might be practicing Petrol Larceny. Also, could the essence of Car Talk really be expressed by one single word? Plus, Bruce in Illinois shares another reminder why you should never buy a car from your brother, a Saturn keeps mooing long past the pasture, and a sure-fire way to test a relationship: cook your girlfriend's transmission. All this, plus a few more signs you may need a new car, this week on Car Talk.

Every last drop

by susanmarcosson

I too hold up the hose to get every last drop out. I paid for it and it's just laying in the hose. Granted it's only a smidgen but at these prices every drop counts. If the guy before me used a higher grade lucky me. Gotta Go.

Running on leaded fuel

by Mike W

Your answer to Question 7 does not sound right to me. I agree that taking out the O2 sensors and cat converters will stop damage to them. But if you take out the O2 sensors, then there is no way for the engine to know the Air fuel ratio. It will thus run open loop. I think that on most vehicles that the ECU will see this as a major problem after a while and shut down the vehicle, or at least take it to limp home mode. So, the way I see it is that the listener will have a terrible time as the ECU will be fighting him all the way. Your advice would work with many older cars, but not recent ones, I think. Love the show!

Heidi's Maneuver

by joewang

I had a response. You mentioned that you basically take a few drops of the previous person's gasoline and you leave drops of your own gasoline for the next guy - a leave a penny / take a penny system that leaves the underlying karma entirely undisturbed. However, how does this square with the different grades of gasoline available at a common pump? I am not anally-retentive enough to suggest that a few drops of 89-octane will corrupt the integrity of my 16 gallons of 93-octane, but it might mean that those who purchase high-test gasoline are (in addition to throwing money down their gas tanks anyway) getting *further* screwed by the pumps. I own a Saab, which requires the premium stuff (much like my girlfriend), but I feel now that I am adding at least a few drops of premium to those behind me while diluting my purchase due to the cheapskates who came before. Your thoughts?
