noob's first 5MPG increase. I'm hooked. This is cool.

I've had my Metro just over a month and have been an ecomodder for only a couple of weeks. My work on this car so far has been just to get it drivable. The last few weeks I have been collecting baseline MPG data with hopes for slow, meager improvements. I just made my first changes and my results were a lot bigger than I expected.

The changes were:
1) removed wiper arms. I have tried this before but it ALWAYS snowed the next day so they went back on. This time they stayed off all week.
2) removed passenger side mirror. I do still need to fabricate a nice looking cover for the hole. I have some plastic to use and I'll shape it up this weekend.
3) Increased tire pressure from 35psi to 48psi. I'm thinking this made the biggest benefit. It just seems to roll a lot better and farther with this change.
I do realize this is only one tank but I do think I can keep this as my new baseline for next set of improvements.

I'm so glad I found this site and all of the information it provides. The conversations regarding testing and results helps me to understand what is worth paying attention to. I'm a happy hypermiler.

Don't forget to also credit the "good weather" you point out in your fuel log. Temperature has a significant impact as well.

Congrats on beating 55 mpg!

Thanks MetroMPG!
Good point about the weather. I don't get credit for that change though. I also realized I need to come up with an error factor for my odometer. I know it is currently around 1% high but I need more data from my GPS. I'll have to update all my fuel logs once I'm comfortable with the data. It will take my average down but shouldn't by much.

I had a friend bring his gps to compare with mine once, they were usually within 2mph but I'm not sure if it was due to lag/update delay (also he didn't know how to access trip odometer on his gps). This variance is what has kept me from just applying my offset. I want to make sure I trust the GPS data within a certain margin of error.

You'll be at 60 in no time.

Hey, I just noticed from your fuel log you ride with a carpool buddy - awesome!

That takes your man-miles from a mere 55mpg to 110 for each mile covered with your passenger. Eat that, single-passenger Prii!

Keep up the good work

I never really considered the man-mile issue. This is awesome!

Thanks all
