Okay, this story will also betray my oldness. First some background. We have a 35 or so year old Coleman that we bought new. (Shopped for a new stove this year; didn't find anything we thought was better.) So of course we carry Coleman fuel. Fortunately we didn't use it all on the camping trip to be described below.
I drive a Subaru Forester (2005). Mark drives it some, too, but mostly me. In the course of driving it in late 2005, early 2006, I discovered that if I let it get below 1/4 tank and made a sharp turn, the car would quit. (Later the vehicle was recalled for a one-way fuel valve problem in the tank. But this event happened before the recall.) I handled the problem by filling the tank more often because it never quit if it was above 1/4 tank. However, I neglected to mention this phenomenon to Mark and at the end of a camping trip in a pretty unpopulated area of Wisconsin, he let the gas level go down until the fuel light came on. Almost immediately the car was inoperable--no gas (or at least no gas that the car could get out of the tank). So we were out in the middle of nowhere on a hot Sunday in rural central Wisconsin with no gas. AAA would come, but it would take 90 min. Then I remembered overhearing a discussion about how Coleman fuel is basically unleaded (what we used to call white in contrast to the color of leaded) gas. So, we put some of the Coleman fuel in the tank (Mark had to pick a milk weed plant to use to get the flapper thing in the gas tank to stay open while he put the Coleman fuel in). The car started and we drove the six miles or so to the next town and filled up with regular fuel, breathing huge sighs of relief. This did not harm the car--I've driven it another 100,000 miles or so with no problems and no repairs.
Interesting--when I started writing this (and also at the time) I thought I was pretty smart to come up with this successful solution. Now I'm thinking the whole thing could have been averted had I simply told Mark about the fuel issue

It's amazing he's put up with me for 37 years!
