The idea is to promote fuel efficiency. And it doesn't have to be by buying a hybrid. Driving philosophy is probably the key to fuel efficiency. If spending a dollar (in this case 50L) can save a hundred (in this case maybe 500L), it works out in the long run.

I believe that one of the most important items in fuel efficiency is tire air pressure. I made a statement about that in a forum last weak. Someone (Tbaleno or xcel) dared me to go back to 34 psi and check out the mileage, speculating that maybe my hike up the mileage charts was more driver than air pressure.

At the point of that writing, I had just posted one of my best tanks. The next day, I changed the oil on the car. Out of curiousity, I checked the air pressure. The tires were at 38-39 psi, down from the 44 psi I had pumped them to about two months ago.

Sheesh. I pumped them back up to 44-45 and thought, air pressure AND driver habits.

At least one person observing these mileage grand prix will see the light and change their driving habits and find 10-20 percent better mileage. That is worth the effort.
