Would you please double check your mileage, against your actual fuel use?

Gary, all my fillups are listed in my Gaslog not my Garage. I have many fillups since I started using SG II. And many fillups before SG. One of the main reasons I bought a SG was because of inconsistencies in pumps, etc. SG picks up the injector pulse and measures the fuel usage.

I have used mile markers to check my speedo accuracy. Within the last 3 days I used Google Earth to plot 2 of the runs I have posted here. Each of these plots show slightly more mileage than SG II or my speedo show. SG shows less miles travelled than my speedo(about 1 per cent).

I do not use any correction factor for SG II. I use the lesser miles the SG registers to figure my mileage. I have stock size tires and gearing in my car so do not have to adjust for that.

In my gas log is listed actual fuel used since 9/27/06. I currently have averaged 55.77 MPG for those fills.
