I have fuel data for every fuel I bought for this car. I also have data on my old truck back till Aug 4th 2003. So I should see a change, though my driving right now is not very consistant.
I got them mirror at my local Meijer (simialr to Walmart). It was $2.40. Most auto parts stores also have small mirrors. it is desigend to be an additon to you outside mirror for seing your blind spot. Right now the ange is set by where and how I taped it on (using the double sided tape provided).
