WRX fuel economy

Subaru WRX fuel economy

I am trying a few fuel saving devices with my wrx and would welcome some feedback from you with your wrx, if you have one.
Whilst on the highway, could you please drive at 60mph, reset your speedo and tell me the fuel consumption reading is on your dash board. As the speedo is a little incorrect could you use a gps for the correct speed.
Thank you for your help in this matter.
Kind regards
Anthony from Brisbane, Australia

The mpg on a test like this will also be affected by the temperature, use of A/C, and any wind. So you should ask for this information also.

I'm going to save you the time and the money by telling you any fuel saving devices are a waste when it comes to fuel economy. The way you drive is the biggest factor!

I drive a school bus. It has an instantaneous mpg readout. I have seen it read as high as 99.9 mpg, which is probably its digital limit. I could quite truthfully say I have seen the bus get nearly 100 mpg, even though its average is probably about 7.

As MatrixDom said above, fuel-saving devices are a waste of money and time. Before you buy any of them, search the Internet for reports from any Consumer Protection agency about them. DO NOT BELIEVE the testimonial letters published in the ads.

+1, yes, a complete rip-off. I failed to read that bit from his original post.
