Just to share a website on improving fuel efficiency and fuel economy tips that I have just come across.
http://www.web-cars.com/mpg/Most of us, like myself, do know most good FC tips. But I happened overlooked the tyre pressure which caused me to lose quite some FC over time. My FC dropped from 13 to 12 to 11.
With my regular route pattern (50 H'way/50 City) unchanged, I tried light driving, off-loading unnecessary stuffs in my boot, my FC still did not move back to before. But after adjusting on the tyre pressure, I am back to a high 12 now.
Cheers.
