As you can see from my earlier post of the gas price data Gas Price History I can be a data pack-rat at times.

Sometimes it’s worthwhile, sometimes not so much.

This summer I had a friend change my spark plugs. We did something incorrectly and my gas mileage has been worse ever since. With the cold weather, the problem has been more dramatic.

Because of my data charts, I know that the change this winter is worse than the normal seasonal variation of gas mileage. I’ll be getting the plugs redone soon and I hope that that will help.
