Hi All. Been reading ecomodder on and off for the past year and finally registered.

I have a question.

I've been using the MPGuino on my 1994 Honda Civic LX, 5 speed for over a year. Works great and am able to drive and consistently get around 45 mpg, and upwards of 57 mpg.

So my daily drive to work I get right at 45 MPG as I pull into the lot, at 36 miles.

Today, it's overcast, bit more humid than usual. I got 51 MPG on my drive to work.

My question is why? From experience the past year, this has occured before. And the only commonality I find is the weather. Overcast, etc.

I know every hill, stop light, when to coast, etc. I even hit typically more lights than usual today.

Perhaps some good gas? Just curious to see if I can reproduce these results every day.

Thanks for reading.
