I have inflated my tires to 40 psi. I also have my oil changed and tires rotated every 5,000 miles. I have also tried the different tips found on the interent (pulse/coast driving where permitted). Whenever I fill the tank, I reset the trip odometer and reset the fuel economy reading on my Nav/radio. While driving home, I try to drive through the city instead of taking the freeway. By doing this, I can generally get the mpgs up to around 52 mpg. However, as soon as I have to go to work and drive on the freeway, it drops down to 30 mpg. Whenever I get stuck in traffic, I can get it to increase up to 32 mpg. But I haven't been able to get it above 32.
Also, I read tonight about using the "L" gear selection on GH's tips. Will this really help? Any thoughts will be appreciated. Also I have checked on the Yahoo groups you mentioned (although I haven't checked recently.)

Thanks,
Rich
