That'll teach me!

Last night I filled up my tank and manually calculated out the mileage and noted it along with what the MFD said. This was my 4th tank and both the calculation and MFD showed 58.2 mpg. Woohoo! I was pretty ecstatic.

So anyway, my wife had to run an errand this morning and since my car get almost 3x the mileage of her van, I lovingly offered it to her. She called my from the end of the driveway and said that the mileage was dropping way down and she didn't know why. I assured her that the car was cold and there was only 2 miles on the new tank and that everything was normal.

About an hour later she got home. The MFD showed 45mpg. I was quite surprised. She told me that it was probably during the road construction where it was stop and go continuously. I scratched my head and said, "That's where it's usually the most efficient"....

I kept going through the things that would cause it to lose mileage. I asked if she was accelerating hard. She said no. I asked if she was holding the accelerator up to the red light. She said no. Finally, I said something about the mileage not being really good above 62 or 63. She said, "62?! I was going 75mph all the time on the highway!"

<knocks head against wall>

 

but, but, my record breaking mileage for this tank is....yeah, I guess you're right. Next tank I'll break 60mpg.....
