It was exactly one year ago that I installed the Blade on my car. From the beginning I have logged my fuel economy per tank on my Mileage Tracker. Excluding some individual mileage tests (mostly short highway runs of about 100 miles) I have used 40 tanks of gas, and driven over 10,000 miles. My average mileage per tank during this whole time was 31.7 MPG. The EPA fuel economy rating for my car is 30 combined. My best tank was 38.9 and the worst came in at 26.6. I did notice a decrease in mileage over the winter, as any car would. Also, it could be that since my cartridge needs to be replaced now, that it lost some of its effectiveness in the last few weeks. This could explain the slightly lower results for spring of this year compared to last.
Now, what everyone wants to see is similar mileage tracking on the car with NO Blade. Well, now you shall have it! Much to my reluctance (since I am not one to consciously increase pollution), I will remove the Blade from my car and keep track of the mileage just as I did before. Let’s see what happens!
