If you are unsure about purchasing a Scangauge, I say go for it. I was unsure, but thought I would try it. I bought a Scangauge through this website and it is great. I plugged it into my 01 Echo and I am having a great time with it. It looks like I am already improving by a few miles per gallon.

Sorry, I am not a good A-B-A tester. I drive about a hundred miles a day to work and back. I don't have much time or money for driving extra miles, but I am still trying to improve my mileage slowly. I bought the 2001 Echo in December 09 with 41K. It got 43 when I first bought it. Since then I pumped up the tires to 40 PSI, installed racing disc wheel covers, and went to Mobil 1 0W20. I got 47.5 mpg on one tank, driving mostly 60 -65 mph. Then the temperature warmed up here in OK and my wife likes the A/C so I got a couple of tanks with 41-43 mpg with the air on and also driving 70-75 mph. I am on the freway a lot and sometimes I have to go with the flow, or I leave late for work, or a couple of times I had to get home to meet a real estate person.

I have gone about 150 miles now on the current tank of gas, and I have used about 1/4 tank. The Scangauge is showing an average of 48.5.

Now that I have a temp gauge I am going to block the grill and see what it does, maybe I will make an air dam if it goes well.This is great.

One other thing. I like to use Phillips 66, even the WalMart gas here is OK. I bought a tank at Loves and my car got 38 MPG. I don't buy the cheap gas anymore or use gas with ethanol. Like I say, the WalMart/ Murphy USA does great.(no ethanol at the Shawnee OK location).

The good mileage can only go up. I am considering a deep cycle battery and alternator delete, I will have to figure out a different pulley or shorter belt. It would be ideal to have a swing away alt I could engage for longer trips.

Now I have to purchase tires. The man at the Firestone dealer recommends the Bridgestone Insignia. Any comments?
I now have Continentals but I think they are cheapies. Should I hold out for the Potenza?
