Default Diff ratio (I searched, nada)

Hi Guys,
I just bought a $70 tank of gas. When I got my CS400 18 months ago a fill-up was $45.
Can I change the final drive ratio to get better mileage? I think the car is geared too low for the highway anyways.
Thanks for your consideration.

The lowest bolt-on rear as far as I know is the stock 3.26 gearing that comes standard in the GS400/GS430 and perhaps other models. If you are around 2600 rpms at 80mph then you have this stock gearing and then..."it is, what it is." The new gas prices do hurt. GL

Thanks for the info and input Rock-a-Lex. The funny thing about the GS400 is if I drive it rather briskly, it gets better mileage than if I soft-peddle it. Maybe I need to drive even faster!
